I have created a new application on C# 2010. After creating a Setup file I came to know that for installation purposes user must have a dot net framework. Is there any way I can get rid of installing dot net framework on a user computer. Each time I try to install my application on the user computer it redirects to install the dot net framework. Any suggestion?
Well that's a problem; because of the design of .NET applications.
Here's some references for you:
Visual C#
"C# (pronounced "C sharp") is a programming language that is designed for building a variety of applications that run on the .NET Framework." [first sentence]
Intro to C# and .NET
As the comments on the question attempt to imply, the .NET Framework is required in order to execute .NET applications.
You have two choices, really:
Require that users have the .NET Framework installed. This is the most common choice, for reasons that will become clear in a moment. It's not unheard-of to have such requirements. It's similar to requiring that a user have Windows installed in order to run your Windows application.
Distribute the .NET Framework with your application installer. This is possible, but less often used because the .NET Framework is large compared to the average application. However, if you must do this, then the option is at least available. Some quick Googling brought me to this helpful blog post.
This isn't possible. C# is built on the .NET framework, so any C# app requires that a version of .NET be available. At http://en.wikipedia.org/wiki/.NET_Framework#History, you can see what .NET framework versions are available in various versions of Windows. The short story is that XP doesn't include anything, Vista includes 3.0, and Windows 7 includes 3.5. If you build for one of these versions, then on those OSes, your users won't need to install anything extra. Using the Client Profile instead of the full .NET can also help reduce or eliminate installs your users will need to do.
Unfortunately No. Its not possible.
To explain it simple terms.
Suppose if you have written only 1 Line of code where you would have simply declared an int variable, who will tell OS that it should create a space in memory?
That framework does exactly that creates basic environment to run your app in a System.
OOPs says about Real-world modeling and Relationships, so let me give you one from it.
Think yourself to be the C# app and Mother Nature/Environment(Greenry) to be .Net Environment.(.Net is called an Environment)
Can you survive without mother nature? From first second that you are in this world, you breathe. Who provides you that oxygen. MOTHER NATURE
While creating installation bundle you can add dot net frame work exe file as prerequisites, then while installing your application it can check whether the system having .net framework or not. if it is not installed it your application can install the frame work.
When you are using managed languages to writing applications you agreed to use their vm, c# codes compiles to IL which needs dot net framework for executing.
.net framework by default exists on windows 7,8,8.1 and 10 and I don't think that this is a challenge.
but if you insist on it so there is a way by using Mono, just remove features that does not support in mono from your project.
first install mono and cygwin, then copy your exe and mono.dll file to a folder, be sure that your file name is not long because in some cases bundling faild,now you can start bundling using mkbundle command.
after bundling finished you have a exe file that can run without .net framework
hope this help you
I have the same issue and want the app to setup using the existing dot net framework version (4.6), because the app setup requires 4.7.2 version that the PC doesn't meet the requirements
I am very much worried that i have seen many applications which i download from internet and they run without installing .net framework or java run time on windows seven, the confusion is, if it is so then in which language all these applications are built? if it is VB6 then it is very old, why latest software are using it, and did Microsoft not build Windows seven in any .net framework, for example if they build it in 3.5 then why it requires to install 3.5 .Net framework to run application.
Also let me know which db these apps usually use.
They could be built using C or C++, or any number of other languages with no runtime libraries (or whose runtime libraries are built into the OS). They may also just use .NET and assume that clients have the .NET framework installed. Finally, they may actually check for the .NET framework and prompt the user to install it if it isn't there, but since you already have it installed you don't see the prompt.
As for which databases they use, it is common to see applications use SQL Server CE or Express, Berkeley DB (BDB), or any number of other small-footprint databases. There is no clear winner in that area, just like in programming languages.
Mostly, Windows 7 has the built-in .NET framework 3.5 So, it automatically runs the application developed in .NET, where as few earlier version of Windows OS, the user didn't have the needed framework in built. It needs to be installed separately.
I am creating a windows application for users with xp, vista or 7 PCs. I was wondering if WPF would work on all these computers, or should I play it safe and just use winforms?
Thanks!
Yes, they will run ok if the computer has the correct .net framework installed.
It would be a good idea to redistribute the framwork with your application. Here is a topic in msdn about how to do it MSDN
Windows Forms has been in .NET since .NET 1, with a few additions in .NET 2. WPF is available in .NET 3 – so, if someone has XP with .NET 2 installed, WPF won't work there.
Apart from that, you can of course install the appropriate .NET framework version on old machines as well. But the implication (WinForms works → WPF works) is wrong.
It will work on all of them, although you won't get the aero glass interface in XP. Obviously, you will need a reasonably up-to-date .NET framework runtime installed on the target machine.
WPF was added in .NET 3.0, so will run on any machine running 3.0 or a newer of the .NET Framework. However, the rendering technologies differ dramatically between WPF and WinForms, so you may need to take that into account. MSDN has a decent set of documents on WPF performance, some of which cover performance-related issues: http://msdn.microsoft.com/en-us/library/aa970683(v=VS.85).aspx.
We use WPF applictaions for XP, Vista and win7 customers and it works fine on platforms.
If you can get the right framework on the machine it will run. So far we are using Version 3.51 and no problems so far.
As other have mentioned, your dependency is on the ability to run the .net framework 3.0. .net 3.0 is supported on the following platforms according to the link below.
Software Requirements
To install .NET Framework 3.0, you
must have one of the following
operating systems installed on the
target computer:
Microsoft Windows XP Home or Microsoft Windows XP Home Professional, with Service Pack 2 or later.
Microsoft Windows Server 2003 family with Service Pack 1 or later.Service Pack 1 or later.

Recently, I came across Mono and MonoDevelop packages in Ubuntu linux. They claim to have a .NET runtime in accordance with CLI. Before installing the packages myself, I would like to know the following:
How powerful is Mono?
Can I develop GUI application for
linux like developing WinForm
applications for Windows.
Is MonoDevelop IDE compatible with Visual Studio IDE. Can I import VS 2008 solutions to MonoDevelop and work?
Does it support .NET 2.0 and above?
EDIT: Adding one more doubt
Is there any way to run the .NET exe (of a winform app) in Linux without building the cod e in linux? In fact I don't have the code for some of the small utilities I developed earlier and would like to run them in linux.
(Strange, markdown starts the enumeration with one, even though I began with 2...)
Yes, you can, but you're limited with 3rd-party components, because the internal implementation is different, and last time I checked (not very long ago), the Mono WinForms implementation made my test app look rather strange (owner-drawn list view). It is not really recommended, though Mono claims that it's now completely WinForms-2.0-compatible.
MonoDevelop is/was a SharpDevelop branch, with the latter having solution support. I don't know if MonoDevelop has. But the cool thing is, you can just develop with Visual Studio and run your compiled apps on Mono. And Mono is, by the way, also available for Windows.
Yes, it does, as far as the CLR goes. As Marc Gravell already wrote, the Windows Foundation libraries are missing, as are a few other (System.Management, for example). But things should mostly work, including ASP.NET 2.0. Mono's application portability guidelines are a good read on this.
1: pretty good, actually. Not all the full framework is there, so if you are writing code that should build on both MS .NET and mono, you need to build and test early against both platforms
4: yes - although things like WPF/WCF/WF (3.0) are missing or slimmed down
I don't know much about the development environment, since I use VSTS (on Windows) and just use a NANT script to do the build on mono...
Define "powerful".
Mono has a WinForms implementation to allow for some level of source compatibility. However, depending on your needs, you might want to use one of the Mono bindings for a Linux native framework, like Gtk# or Qyoto
Wouldn't know.
Depends on what parts of .NET you mean. C# the language seems to be pretty current, things get fuzzier the closer you get to the enterprisey features as was already mentioned.
To sum things up, if you'll be using Mono as a separate target platform, you're likely to have good results. If you want a no-code-changes-required .NET compatibility layer, less so.
Very powerful. There are no major bugs in the core implementation. It is not a science project. The deficiencies are mostly where you would expect, the newest APIs (Microsoft inherently has a first-mover advantage there).
Yes. We just finished a project where most of the GUI code was developed in WinForms on Windows. I was able to work on it using Ubuntu without major headaches. That said, this is one of the hardest parts of the API, and there are still issues. See http://mono-project.com/WinForms for details.
Don't know, as I don't use it.
Yes, though again, there may be some missing APIs in the runtime.
Note, I use Ubuntu Hardy (8.04).
Mono is mighty powerful. It has all the .Net muscle on a very strong open source skeleton.
When you say "develop GUI application for linux like developing WinForm applications for Windows" I understand that you are asking about a visual designer that will allow you to quickly create the UI. Yes, it is possible. MonoDevelop has Stetic - a built-in visual designer for Gtk#. There is also QyotoDevelop which enables QT support in MonoDevelop.
Yes, MonoDevelop natively supports VS project/solution file format. You can use the same code base to compile your app with VS in .Net on Windows and win MD in Mono on Linux.
Currently Mono supports C# 3.0 with some stuff beyond that already implemented and a lot in the pipeline.
Yes, in many cases it is possible to run a .Net compiled app in Mono, however with MonoDevelop's support for VS solutions it doesn't really matter. It takes as much as pressing F7 to rebuild the whole project, so the effort is really negligible. The best tool for checking if your application can run in Mono is MoMA.
Mono is very powerfull, sometimes even more powerfull than Microsoft's implementation. link text
Yes you can. Winforms 2.0 is supported
I believe so.
Yes it does. C# 3 is supported and just look at winforms and the asp.net implementation to see how much is supported from each of the projects. Look at http://mono-project.com
I use WinForms in mono. The 2.x releases are very good.
I develop forms in visual-studio on windows, and run them in Linux, with zero code changes. Yes, forms look a little different than on XP, but then again, an XP-themed GUI would look kind of strange in GNOME.
If you are just getting started, stick with WinForms, while you get comfortable with Mono/Linux. However at some point you might want to investigate GTK.
I am writing an app to discover what features exist on a pc. The user would go to a web page, download the app and execute it (with all the appropriate warnings, this is not spyware). The app would use the standard MS api to determine such things as connection speed, installed memory, firewall health, etc. Writing the app is not a problem, I could use Scripting Host, C#, C++, etc. The question is, if I chose C# is there any guarantee that a certain flavor of windows would have .net installed? The target pc is XP SP2 or better and Vista.
Thanks for the help.
Vista does have .NET 3.0 installed. XP SP2 doesn't have any .NET framework installed by default.
You may want to read Scott Hanselman's blog post SmallestDotNet: On the Size of the .NET Framework, specifically the What's the "Client Profile?" section:
The Client Profile is an even smaller
install option for .NET 3.5 SP1 on XP.
It's small 277k bootstrapper. When
it's run on a Windows XP SP2 machines
with no .NET Framework installed, it
will download a 28 meg payload and
give you a client-specific subset of
.NET 3.5. If the Client Profile
bootstrapper is run on a machine with
any version of .NET on it, it'll act
the same as the 3.5 SP1 web installer
and detect what it needs to download,
then go get it. There's more details
in the Client Profile Deployment Guide.
Mehrdad has it right, SP2 has no .NET installation by default. It's worth noting, however, that you can provide a download for users who lack the runtimes, providing whatever version you are using bundled in. It's an option through the creation wizard of one of the setup packages.
Like the above have stated, .NET is not installed by default. However if you were using ASP .NET with C#, many things could be gotten just by viewing the website (computer name, domain, userid, etc).
Well if you are afraid of use .Net but the client does not have installed, you could try a product which takes all your .Net dependencies and creates an isolated installer that will run on every computer, with all the risks that this could raise to your users (no updates, no bug fixes and such).
Here is the link:
http://www.remotesoft.com/linker/index.html
Hope this helps.
I would suggest avoiding .NET if possible since most versions of Windows come without it and the installer will just add to the pain of using your program. Unless its a large application already... but from the sound of it you can get what you want with a few KB's of C++ executable (i.e. almost instant download).
Pre-Vista: there is a significant chance that .NET will not be installed. And event if it is it may be 1.0 or 1.1.
Vista includes .NET 3.0 in RTM, but it is an optional component in Server 2008.
I would also be considered about the size and start up time of .NET. Overall this sounds like something to be written with as few dependencies as possible.
EDIT: Corrected Vista included 3.0 not 3.5.
