I've decided to start writing an iPhone app and coming from a c# background, I thought I'd start developing it with mono.
Though this question may be subjective, I'd love some guidance from you.
Is it safe to develop my app using this technology, or should I buy some books and start learning objective C?
I know Adobe were going to release a feature that allows you to build iPhone apps using Flash CS5, but this didn't last long.
I appreciate your feedback.

Monotouch is doing a great job of keeping up to date (usually within 24 hours of api updates) so just saying you have no idea about xyz but you know abc is much better than it is a bit silly. Monotouch has some serious advantages over obj c - for instance obj c has only been updated something like twice in the last twenty years!! expect good XML, regex, Http support? Think again. Linq in Obj c? never. Good OS community? Not likely. There's plenty of reasons to use MT, aside from C# being a far superior language. Being able to re-use a good percentage of your code in MonoDroid is one. Though there is word that apple are creating a new language - I'm not holding out too much hope for it. We'll see I guess.
I learned Obj C before getting into MT and the reason I went with MT is that using Obj C is like stepping back into the 90s. It just doesn't have any modern language features and is too far behind the curve. Create your bleeding edge apps with their archaic langauge? Thanks but no thanks.
None of us except people who work very closely with the OS and the App store policy in Apple would know whether it is "safe" to develop apps using this technology. Apple can say no anytime in the future, but we don't know. What we know is that all the compiled code has to be in C, C++, or Obj-C. However there's one catch: In some cases you can run interpreted languages.
If I were you, I'd go with Objective-C. We know that Apple supports it fully, it's been in there for almost 20 years. It's not that hard to learn since you know C#. I came from C++/C and it took me about a month or so to learn half of the frameworks. There are many other frameworks which I didn't learn because they're not applicable in my apps (such as accelerators, GPS, OpenGL ES, etc). You probably can get away with this too.
Once again, there's also another way: build it with HTML5. However that way you'd have to consider what your app'll do when it's opened with Safari desktop, Firefox, IE, etc.
The iPhone dev agreement is pretty clear that C# is not an accepted technology for developing iPhone apps. Regardless, Monotouch apps have still been accepted to the app store to date without any problems. My suggestion is to keep in touch with the Monotouch forums to see what their stance is on this issue and make your decision based on that. The long term safe bet is to go learn Objective-C.
Recently Apple changed the clause relating to the third party development tools now stating that if you have prior approval you can use them. I haven't seen any official word that Mono will be allowed though.
If you are coming from a c# background I would highly recommend learning Obj-C because it always helps knowing another language and you could pick it up reasonably easily. Have a look at the stanford University iPhone lectures, they were the best resource when I was learning.
Although I haven't personally used C# or Mono, the iOS SDK once you get to know it has some really great work behind it making it both easy and powerful once you get used to it and I would be surprised if Mono took advantage of it all.
I think it's important to learn the language the frameworks for your platform of choice were written in. Then you can understand more why the frameworks are the way they are, and often anticipate behavior or API calls just based on knowing what is typical for the language and framework.
On top of that there is now a ton of support for blocks across the API (iOS4 and on only), which may take some time to be incorporated into MonoTouch. Overlay frameworks are always a step behind the base platform so it's nicer to be using the frameworks directly.
It's now been months since the Flash debacle and Monotouch and Unity are still rocking along.
As developers in a .NET shop we're looking at expanding into iOS development. After prototyping some fairly basic stuff in Objective-C, We're 100% committed to using Monotouch, it's worth every penny.

After sitting through a session today on Mono at a local .Net event, the use of MonoTouch was 'touched' upon as an alternative for iPhone development. Being very comfortable in C# and .Net, it seems like an appealing option, despite some of the quirkiness of the Mono stack. However, since MonoTouch costs $400, I'm somewhat torn on if this is the way to go for iPhone development.
Anyone have an experience developing with MonoTouch and Objective-C, and if so is developing with MonoTouch that much simpler and quicker than learning Objective-C, and in turn worth the $400?
I've seen this question (and variations on it) a lot lately. What amazes me is how often people respond, but how few answer.
I have my preferences (I enjoy both stacks), but this is where most "answers" start to go wrong. It shouldn't be about what I want (or what anybody else wants).
Here's how I'd go about determining the value of MonoTouch - I can't be objective, obviously, but I think this is pretty zealotry-free:
Is this for fun or business? If you wanted to get into consulting in this area, you could make your $399 back very quickly.
Do you want to learn the platform inside-out, or do you "just" want to write apps for it?
Do you like .Net enough that using a different dev stack would take the fun out of it for you? Again, I like both stacks (Apple and Mono), but for me MonoTouch makes the experience that much more fun. I haven't stopped using Apple's tools, but that's mainly because I really do enjoy both stacks. I love the iPhone, and I love .Net. In that case, for me, MonoTouch was a no-brainer.
Do you feel comfortable working with C? I don't mean Objective-C, but C - it matters because Objective-C is C. It's a nice, fancy, friendly OO version, but if pointers give you the heebie-jeebies, MonoTouch is your friend. And don't listen to the naysayers who think you're a dev wuss if it happens that you don't like pointers (or C, etc.). I used to walk around with a copy of the IBM ROM BIOS Pocket Reference, and when I was writing assembly and forcing my computer into funny video modes and writing my own font rendering bits for them and (admittedly trashy) windowing systems, I didn't think the QuickBasic devs were wusses. I was a QuickBasic dev (in addition to the rest). Never give in to nerd machismo. If you don't like C, and if you don't like pointers, and if you want to stay as far away from manual memory management as possible (and, to be fair, it's not bad at all in ObjC), then... MonoTouch. And don't take any guff for it.
Would you like to target users or businesses? It doesn't matter much to me, but there are still people out there on Edge, and the fact is: you can create a far smaller download package if you use Apple's stack. I've been playing around with MonoTouch, and I have a decent little app going that, once compressed, gets down to about 2.7 MB (when submitting your app for distribution, you zip it - when apps are downloaded from the store, they're zipped - so when figuring out if your app is going to come in under the 10MB OTA limit, zip the sucker first - you WILL be pleasantly surprised with MonoTouch). But, MT happiness aside, half a meg vs. nearly three (for example) is something that might be important to you if you're targeting end users. If you're thinking of enterprise work, a few MB won't matter at all. And, just to be clear - I'm going to be submitting a MT-based app to the store soonishly, and I have no problem whatsoever with the size. Doesn't bother me at all. But if that's something that would concern you, then Apple's stack wins this one.
Doing any XML work? MonoTouch. Period.
String manipulation? Date manipulation? A million other little things we've gotten used to with .Net's everything-AND-the-kitchen-sink frameworks? MonoTouch.
Web services? MonoTouch.
Syntactically, they both have their advantages. Objective-C tends to be more verbose where you have to write it. You'll find yourself writing code with C# you wouldn't have to write with ObjC, but it goes both ways. This particular topic could fill a book. I prefer C# syntax, but after getting over my initial this-is-otherworldly reaction to Objective-C, I've learned to enjoy it quite a bit. I make fun of it a bit in talks (it is weird for devs who're used to C#/Java/etc.), but the truth is that I have an Objective-C shaped spot in my heart that makes me happy.
Do you plan to use Interface Builder? Because, even in this early version, I find myself doing far less work to build my UIs with IB and then using them in code. It feels like entire steps are missing from the Objective-C/IB way of doing things, and I'm pretty sure it's because entire steps are missing from the Objective-C/IB way of doing things. So far, and I don't think I've sufficiently tested, but so far, MonoTouch is the winner here for how much less work you have to do.
Do you think it's fun to learn new languages and platforms? If so, the iPhone has a lot to offer, and Apple's stack will likely get you out of your comfort-zone - which, for some devs, is fun (Hi - I'm one of those devs - I joke about it and give Apple a hard time, but I've had a lot of fun learning iPhone development through Apple's tools).
There are so many things to consider. Value is so abstract. If we're talking about cost and whether it's worth it, the answer comes down to my first bullet item: if this is for business, and if you can get the work, you'll make your money right back.
So... that's about as objective as I can be. This is a short list of what you might ask yourself, but it's a starting point.
Personally (let's drop the objectivity for a moment), I love and use both. And I'm glad I learned the Apple stack first. It was easier for me to get up and running with MonoTouch when I already knew my way around Apple's world. As others have said, you're still going to be working with CocoaTouch - it's just going to be in a .Net-ized environment.
But there's more than that. The people who haven't used MonoTouch tend to stop there - "It's a wrapper blah blah blah" - that's not MonoTouch.
MonoTouch gives you access to what CocoaTouch has to offer while also giving you access to what (a subset of) .Net has to offer, an IDE some people feel more comfortable with (I'm one of them), better integration with Interface Builder, and although you don't get to completely forget about memory-management, you get a nice degree of leeway.
If you aren't sure, grab Apple's stack (it's free), and grab the MonoTouch eval stack (it's free). Until you join Apple's dev program, both will only run against the simulator, but that's enough to help you figure out if you vastly prefer one to the other, and possible whether MonoTouch is, for you, worth the $399.
And don't listen to the zealots - they tend to be the ones who haven't used the technology they're railing against :)
There is a lot of hearsay in this post from developers that have not tried MonoTouch and Objective-C. It seems to be mostly be Objective-C developers that have never tried MonoTouch.
I am obviously biased, but you can check out what the MonoTouch community has been up to in:
http://xamarin.com
There you will find several articles from developers that have developed in both Objective-C and C#.
So, my answer to a previous similar question is to learn Objective-C. (Also, don't forget about debugging support)
This will probably offend some but to
be honest, if you are going to do any
serious development, you should learn
Objective-C. Not knowing Objective-C
in iPhone development will just be a
hindrance. You won't be able to
understand many examples; you have to
deal with the quirks of Mono whereas
if you had a working knowledge of
Objective-C you could get a lot more
out of the platform documentation.
Personally, I don't understand the
position that says increasing the
amount of information you need in
favor of using Mono over the
platform's native language. It seems
somewhat counterproductive to me. I
think if this is a very expensive
proposition (learning a new language)
then it may be worthwhile spending
some time on fundamental programming
concepts so that learning new
languages is a fairly cheap
proposition.
Another user also wrote this:
Monotouch is easier for you now. But harder later.
For example, what happens when new seeds come out you need to test against but break MonoTouch for some reason?
By sticking with Mono, any time you are looking up resources for frameworks you have to translate mentally into how you are going to use them with Mono. Your app binaries will be larger, your development time not that much faster after a few months into Objective-C, and other app developers will have that much more of an advantage over you because they are using the native platform.
Another consideration is that you are looking to use C# because you are more familiar with the language than Objective-C. But the vast majority of the learning curve for the iPhone is not Objective-C, it is the frameworks - which you will have to call into with C# as well.
For any platform, you should use the platform that directly expresses the design philosophy of that platform - on the iPhone, that is Objective-C. Think about this from the reverse angle, if a Linux developer used to programming in GTK wanted to write Windows apps would you seriously recommend that they not use C# and stick to GTK because it was "easier" for them to do so?
Using Mono is not a crutch. There are many things that it adds to the iPhone OS. LINQ, WCF, sharable code between a Silverlight app, an ASP.NET page, a WPF app, a Windows Form app, and there's also mono for Android and it will work for Windows Mobile as well.
So, you can spend a bunch of time writing Objective-C (You'll see from many studies where the exact same sample code in C# is significantly less to write than OC) and then DUPLICATE it all for other platforms. For me, I chose MonoTouch because the Cloud App I'm writing will have many interfaces, the iPhone being only one of them. Having WCF data streaming from the cloud to MonoTouch app is insanely simple. I have core libraries that are shared among the various platforms and then only need to write a simple presentation layer for the iPhone/WinMobile/Android/SilverLight/WPF/ASP.NET deployments. Recreating it all in Objective-C would be an enormous waste of time both for initial dev and maintenance as the product continues to move forward since all functionality would have to be replicated rather than reused.
The people who are insulting MonoTouch or insinuating that users of it need a crutch are lacking the Big Picture of what it means to have the .NET framework at your fingertips and maybe don't understand proper separation of logic from presentation done in a way that can be reused across platforms and devices.
Objective-C is interesting and very different from many common languages. I like a challenge and learning different approaches... but not when doing so impedes my progress or creates unnecessary re-coding. There are some really great things about the iPhone SDK framework, but all that greatness is fully supported with MonoTouch and cuts out all the manual memory management, reduces the amount of code required to perform the same tasks, allows me to reuse my assemblies, and keeps my options open to be able to move to other devices and platforms.
I switched. Monotouch let's me write apps at least 3-4 times as fast (4 apps per month compared to my old 1 per month in Obj C)
Lots less typing.
Just my experience.
If this is the only iPhone app you will ever develop, and you also have zero interest in developing Mac applications, ever, then MonoTouch is probably worth the cost.
If you think you'll ever develop more iPhone apps, or will ever want to do some Mac native development, it's probably worth it to learn Objective-C and the associated frameworks. Plus, if you're the type of programmer that enjoys learning new things, it's a fun new paradigm to study.
Personally I think you'll have a better time just learning Objective-C.
In short:
"Learning Objective-C" is not a daunting as you might think, you may even enjoy it after just the first few weeks
You are already familiar with the "C style" syntax with lots of *&(){}; everywhere
Apple has done a very good job of documenting things
You'll be interacting with the iPhone the way Apple intended, which means you'll get the benefits directly from the source not through some filter.
I have found that the projects like Unity and MonoTouch are supposed to "save you time" but ultimately you'll need to learn their domain specific language anyway and will have to side-step things at times. All that is probably going to take you just as long as it would to learn the language you were trying to avoid learning (in calendar time). In the end you didn't save any time and you are tightly coupled to some product.
EDIT: I never meant to imply anything negative about .NET I happen to be a big fan of it. My point is that adding more layers of complexity just because you aren't yet comfortable with the quirky objc bracket notation doesn't really make much sense to me.
2019 update: It's 7 years later. I still feel the same way if not more so. Sure, 'domain specific language' may have been the wrong term to use, but I still believe it's much better to write directly for the platform you are working with and avoid compatibility layers and abstractions as much as possible. If you are worried about code reuse and re-work, generally speaking any functionality your cross platform app needs to perform can probably be accomplished with modern web technologies.
To add to what others have already said (well!): my feeling is that you're basically doubling the number of bugs you have to worry about, adding the ones in MonoTouch to the ones already in iPhone OS. Updating for new OS versions will be even more painful than normal. Yuck, all around.
The only compelling case I can see for MonoTouch is organizations that have lots and lots of C# programmers and C# code lying around that they must leverage on iPhone. (The sort of shop that won't even blink at $3500.)
But for anyone starting out from scratch, I really can't see it as worthwhile or wise.
Three words: Linq to SQL
Yes it is well worth the $.
Something I'd like to add, even though there's an accepted answer - who is to say that Apple won't just reject apps that have signs of being built with Mono Touch?
I would invest the time in Objective-C mainly because of all the help you can get from sites like this. One of the strength's of Objective-C is that you can use C and C++ code, and there is a lot of projects out there that are well tested.
Another thing is that you're code (language of choice) will be supported by apple. What it iOS 5.x for instance removes the support for a third party solution like MonoTouch? What will you tell your customers then?
Maybe its better to use a platform independent solution like HTML5 if you're not entire ready to move to Objective-C?
I've been using MonoTouch for a few months now, I ported my half finished app from ObjectiveC so I could support Android at some point in the future.
Here's my experience:
Bad bits:
Xamarin Studio. Indie developers such as myself are forced into using Xamarin Studio. It is getting better every week, the developers are very active on the forums identifying and fixing bugs, but it's still very slow, frequently hangs, has a lot of bugs and debugging is pretty slow also.
Build times. Building my large (linked) app to debug on a device can take a few minutes, this is compared to XCode which deploys almost immediately. Building for the simulator (non-linked) is a bit quicker.
MonoTouch issues. I've experienced memory leak issues caused by the event handling, and have had to put in some pretty ugly workarounds to prevent the leaks, such as attaching and detaching events when entering and leaving views. The Xamarin developers are actively looking into issues like this.
3rd party libraries. I've spent quite a time converting/binding ObjectiveC libraries to use in my app, although this is getting better with automated software such as Objective Sharpie.
Larger binaries. This doesn't really bother me but thought I'd mention it. IMO a couple of extra Mb is nothing these days.
Good bits:
Multi-platform. My friend is happily creating an Android version of my app from my core codebase, we're developing in parallel and are committing to a remote Git repository on Dropbox, it's going well.
.Net. Working in C# .Net is much nicer than Objective C IMO.
MonoTouch. Pretty much everything in iOS is mirrored in .Net and it's fairly straight forward to get things working.
Xamarin. You can see that these guys are really working to improve everything, making development smoother and easier.
I definitely recommend Xamarin for cross platform development, especially if you have the money to use the Business or Enterprise editions that work with Visual Studio.
If you're solely creating an iPhone app that will never be needed on another platform, and you're an Indie developer, I'd stick with XCode and Objective C for now.
As someone with experience with both C# as well as Objective-C, I'd say for most people Xamarin will be well worth the money.
C# is a really good designed language and the C# API's are good designed as well. Of course the Cocoa Touch API's (including UIKit) have great design as well, yet the language could be improved in several ways. When writing in C# you will likely be more productive compared to writing the same code in Objective-C. This is due to several reasons, but some reasons would be:
C# has type inference. Type inference makes writing code quicker, since you don't have to "know" the type on the left-hand side of an assignment. It also makes refactoring easier and more saver.
C# has generics, which will reduce errors compared to equivalent Objective-C code (though there are some work-arounds in Objective-C, in most situations developers will avoid them).
Recently Xamarin added support for Async / Await, which makes writing asynchronous code very easy.
You'll be able to reuse part of the code base on iOS, Android and Windows Phone.
MonoTouch largely implements the CocoaTouch API's in a very straightforward way. E.g.: if you've got experience with CocoaTouch, you'll know where to find classes for controls in MonoTouch (MonoTouch.UIKit contains classes for UIButton, UIView, UINavigationController, etc..., likewise MonoTouch.Foundation got classes for NSString, NSData, etc...).
Xamarin will give users a native experience, unlike solutions like PhoneGap or Titanium.
Now Objective-C has some advantages over C#, but in most situations writing apps in C# will generally result in less develop time and cleaner code and less work to port the same app to other platforms. One notable exception might be high-performance games that rely on OpenGL.
The cost of the MonoTouch library is entirely beside the point. The reason you shouldn't use Mono for your iPhone apps, is that it is a crutch. If you can't be bothered to learn the native tools, then I have no reason to believe that your product is worth downloading.
Edit: 4/14/2010 Applications written with MonoTouch aren't eligible for the iTunes Store. This is as it should be. Apple saw plenty of shallow ports on the Mac, using cross-platform toolkits like Qt, or Adobe's own partial re-implementation of the System 7 toolbox, and the long and short of it is they're just not good enough.
I'm a little ashamed for asking this, because, you know, I've been very anti-MS for a long time. I have been fortunate enough as to make a living outside Visual Studio. As I grown older there are "some" things I would like to try, and to be very honest, this Q&A site has inspired me and I realize that VS and Windows Development doesn't suck that much. Hey, after all C# was designed after Java, and now Java is copying back some features from the child language. And Windows vista is the first decent version since windows came to light.
Anyway, to any +3,000 user in the audience, you may delete all the above crap and keep the following:
Do you have, links, resources, tutorial aimed to learn Windows development coming from strong Java background?
I'm very interested in Windows manipulation (that is the actual window, the frame, get the name, get foremost app etc., resize it programatically, etc.) and in Windows Search API among other minor API's. My interest after all is to integrate them with my Java apps through JNI or JNA.
I've read many tutorials and links over the MSDN, and I actually understand the API it self. I've grabbed a copy of C# and C++ Express and actually got some basic samples running.
My problem is I don't get the big picture of the whole architecture (because, well, it is big). The classes have hundreds of methods, and it not that clear to me who calls them. (I had this same opinion when I first look at the Java's Javadoc API.) I don't know some basic common objects, for instance HWCD (or something like that) that it turned out to be the very window handler, but every single tutorial I read give that for granted (as if WHCD or what ever it is, was a very descriptive name).
I don't know exactly the difference between Win32, COM, COM+, DCOM, Windows SDK ADO, and some other technologies. I mean, I know them at some degree and by common sense, but while reading the tutorials or the API I get confused. I've tried to grab some "beginner" tutorials, but they are aimed for absolute 0 programmers using Visual Basic (yiak! , THAT was the main reason I kept away from MS for so many years in first place.)
I do understand .NET framework, managed code, unmanaged code, C# basics, CLR and related stuff, because well, they are SO similar to the Java platform that it is almost transparent.
So, after all my rants and honest opinions about MS development:
What's the best way to learn Windows Development for a non absolute beginner (in programming) but absolute new to Windows APIs itself? What would be a good path?
The Petzold is your new best friend, and MSDN is your new Javadocs. Make sure you have a good understanding of C before you dive into it though. The Forger has a great beginner tutorial too if you're interested. A great place to hang out while learning is #WinProg on efnet irc, plenty of win32 gurus ready to help.
I'm going to suggest an alternate path (with less resistance). Have you looked at WPF yet? It's the new GUI toolkit that lets you create sexy interfaces (like those found in Vista).
That may be enough to keep you interested while easing into more advanced development. From there you can jump into the jungle of the Win APIs (if you choose).
Just a thought, as that path would be more interesting for me. Your mileage may vary, of course.
I strongly recommend getting yourself a copy of "Win32 Programming". It explains the basic DNA of WINDOWS - and this is valid if you are programming with the old C++ win32, the new C# WinForms and also the future Windows Presentation Foundation.
In a nutshell, a Windows program consists of a WinMain. When first started the app registers its window class with the system, initializes and then starts a message loop which continues till WM_QUIT is encountered. The system (OS) keeps pumping messages like keyboard or mouse click etc to the message Q of the application. In Windows, at any point of time there is only one active Window - so the OS knows whom to send the message to.
Well things like these are described in detail in the above book.
COM (COM+, DCOM) are not really related to Windows. When Word, Excel became popular and it was required to be able to access Excel from Word (viceversa) they came up with the AcitveX technology which is kind of the root for COM etc. You can get started with "Essential COM" by Don Box.
One warning: in the Microsoft world, there are two ways to program - to go the boiler plate way (write everything yourself) or use frameworks (MFC, ATL-COM....). It is recommended to do a bit of boiler plate so that you know the basics.
Having made the same conversion a year ago I can say that there's a lot of literature specifically for learning c# from a Java background. This was my first into which I found really useful for learning the important differences / features of C#:
C# from a Java developer's perspective
And there are also books which may be worth a look at (google 'c# for java programmers'). As JohnT said MSDN library is the equivalent of JavaDocs API, but I found it really frustrating to use. The best way to learn is to grab a copy of Visual Studio express and start playing around. Use intellisense to explore classes and methods. Find a small program you wrote in Java and try to reproduce it in C#. Start with simple problems, use google to solve them. You'll find it hard for the first week, but trust me, it will come to you surprisingly quickly!
My company has an existing established WinForm application which in running on WinXP. The application does alot of sound processing using DirectSound.
My company would like to evaluate Mono, as an alternative on a per workstation cost to Vista/Win Server 2008.
I've heard that different estimates, ranging from 'it will work easily on Mono' to 'it could take months of recoding in certain cases to get a WinForm app to run with Mono on Linux'.
Does anyone have a good real world experience with this?
A good link reference?
I would like to get a better idea before I commit to testing.
Thanks!
The WinForms part will be easy, you may have to do very little as Mono now claims to support Winforms 100%, however all the DirectSound calls will have to be rewritten to use an API available on Linux, ALSA being the obvious choice.
I have written small apps in VS 2005 and ported them with ease to Mono. If you do a lot of P/Invokes, then you'll have to take that into account, as those may have to be completely rewritten or rethought.
Also, check out MOMA: "The Mono Migration Analyzer (MoMA) tool helps you identify issues you may have when porting your .Net application to Mono. It helps pinpoint platform specific calls (P/Invoke) and areas that are not yet supported by the Mono project."
Mono can help you move the managed code, but it will not help you move the audio layer.
Sadly, the .NET framework does not provide a comprehensive API for audio processing. It merely provides a way of playing back a small sound sample, and it is not even very good at this (See Jeroen's post about audio gaps when running the C64 emulator under IKVM).
You will have to research which Linux API maps best to what your audio application is doing.
Lennart Poettering blog entry on audio is an excellent starting point:
http://0pointer.de/blog/projects/guide-to-sound-apis.html
Once you decide on an API, just like in Windows, you will have to P/Invoke the API that is right for you.
I'd like to study up on the latest technologies for writing Windows desktop apps. My last experience was with VC++ 6 using MFC. The landscape seems more complex these days, I'm not sure if I should learn .NET, don't really know what Windows forms, WPF are etc. All I want to do is be able to write some simple Windows GUI apps, probably using & learning C# along the way.
Any recommendations on books to read etc?
Also, is the free version of VC2008 good enough for writing small apps?
I would go with .NET and WPF. WinForms is still available, but is really a legacy branch of .NET at this point, and not worth learning if you are starting from scratch. WPF offers a lot of good features, and is pretty use to get up and running with.
I found "Windows Presentation Foundation Unleashed" a good introduction to WPF. It explained the foundational concepts well and wasn't just one of those 2,000 page tutorials full of screen shots.
I recommend Head First C#. If you've programmed in C++ before, you should be up to speed fairly quickly.
alt text http://ecx.images-amazon.com/images/I/51u3iZDwU6L._SL500_AA240_.jpg
MFC has changed very little since vc 6 you should be able to pick it up again with little trouble and while this skill set may not be as indemand as .net There are still jobs out there and you can still write compelling windows applications.
I would start with reading C# online tutorials and articles from Code Project
Well, if you are using C# you are using .NET. .NET really is a great framework for creating desktop applications. I think you are on the right track.
Actually, I learned ALOT just browsing Stack Overflow and posting a few questions here. I think the Visual Studio Express tools are great for new developers. I'm also a fan of Bob Tabor's stuff (http://www.learnvisualstudio.net/) He does have some free stuff located on MSDN here that was really helpful for a guy like me with a mostly scripting background. You may be ahead of me because of your past experience so perhaps it's too rudimentary for you.
I'm really starting to enjoy C# and .NET and just started to be able to read code and for the most part, comprehend it. It was quite a breakthrough for me.
