Time bomb needed in asp.net application
I've done developing my app in C#. I need some info of how I can implement 'trial' functionality for my app (I want to let the user use the app for 30 day for example)
Take a look at these tools:
.NET Licensing Pro
SerialShield SDK
PC Guard
Maxtocode
DeployLX Licensing
There are a lot of good answer in this question
Time bomb needed in ASP.NET application
There's also the solutions from Xheo, in particular DeployLX.
A specific commercial solution I've used is from Aladdin. They offer a USB dongle or a "software dongle" that allows you to pick and choose what features are enabled/disabled. The USB dongles even come with a battery-operated clock sealed in them so that gaming the system clock doesn't get around your protection.
Some people may say that any system like this can be broken. This is true. However, I've found Aladdin tools can be used to make cracking very difficult. Pair that with improving your protection on subsequent releases and what you get is a product that takes a lot of time and effort (cost) to break.
There's a related discussion on this SO question: Software evaluation licensing.
You can also check LicenseSpot which gives you the ability to control the license via the online license manager with activation, revoking and trial extensions.

I have done some digging and poking and have come up short. I am looking for a freeware tool that I can give to my users to set Large Address Aware after I have given my application.
Background:
I work on a piece of software that has ~500 users. A small number (maybe 25?) of these users are running into memory problems when doing multiple large searches. The application is 32bit and is being run on everything from Win XP machines with 2 gigs of ram (if they are lucky) to users who are running 64bit Windows 7 with 4+ gigs of ram.
My team considered setting LAA after compile using the post build events, but a few of the websites I came across said there could be problems on older systems. If this information is wrong though and it would work with the old (small amount of ram) machines I wouldn't need the tool.
Thanks all.
Personally I like CFF Explorer. It can mark programs LAA as well as a ton of other features.

I need to develop an evaluation tool using C# that will run on the system for hours and then will show the overal performance of the system.
The system is supposed to run a service and we want to evaluate how this service is affecting the performance of the system. Will be great if I could use the performance counters that are available in "Windows Performance Monitor"... I'm not sure if there is any API available for developers to use them.
I was just looking for suggestions...
Thanks
If it were me, I'd use perfmon. The advantages are:
Well known data archiving model that offers multiple formats.
Existing tooling to slice and dice the data, including visualization.
Integrates with other systems if the client cares (ie lets them suck the data in to other performance tooling).
Someone else's code. :)
You can wrap perfmon and invoke it programatically if you want. Worst case just invoke it via the command line and start/stop collection that way.
Of course you can also expose your own performance counters for app specific stuff too. There are loads of APIs for this for just about every programming environment I can think of on Windows, including of course C#.
I would strongly suggest you use an existing option like automating the collection of WPM statistics.
otherwise C# may not be the best choice since hardware is almost completely abstracted away from the code by the runtime. additionally the application may require sufficient resources and time to contaminate your results. usually the performace cost between C++ and C# is neglible, but in this case could be a problem.
Good luck.

I'm lookin at a job description that lists this as a responsibility:
Design, develop, and test software for analytical scientific instruments with an emphasis on Host application code
This is a software engineer job in the electronics manufacturing field so i imagine there will be a heavy emphasis on embedded software and drivers as well as electronics test fixturing code.
So what specifically does host application code refer to? I did some googling and found this link which suggests it has to do with windows powershell. This would make sense because they also ask for experience with C# or VB.net and visual studio. It looks like they are very windows oriented. But I'm still not entirely sure about what they're looking for.
On its own it does not mean anything, and almost certainly nothing to do with Powershell.
Whoever wrote it knew what it meant to them, but it has lost all meaning without context. You simply need to ask the recruiter to elaborate - there is no shame in that, and in fact it would probably be to your credit to show that initiative.
Try:
"Sounds interesting; can you give me more information?
If I had to guess from the other information you have given, I would imagine that it refers to software running on a PC connected to a number of instruments (perhaps via GPIB, Ethernet, USB, Serial or other interfaced or PCI cards plugged directly into the PC).
Many companies use National Instruments' LabView for this for this sort of application. I can think of many reasons not to use LabView, but it might be a question for you to bring up in an interview.
I'm guessing it just means code for the scientific instruments - the instruments will 'host' the embedded code.
I would assume that host application software refers to PC-based windows applications that interface to the instruments (via serial, usb, ethernet, or other interface) and are used to configure the instruments, analyze and store data from the instruments, and/or test the instruments.

We have a software which we use in-house for our day to day work.
It is like a customize CRM (sort of) and Bug Tracking software. We had a small team of 3 developers who had developed this software. Now this team is also working on other assignments.
Recently we are receiving a lot of request for adding functionality from users (who are our employees and all of them are developers working of different projects) in our firm. The original team that created this software does not have enough time to work on enhancing this software. So instead of spending a lot of time in updating as per request and the updating the executable of software for each user, we want to implement a programming/scripting solution that is if possible free and open source.
I was thinking of adding support for a language which is similar to C# to our application. This way the developers will add the features that they require on their own in their spare time if they really need a feature!
Can anyone point me to some such implementation already existing?
I don't know if I am taking the right decision or not regarding C# I would like to get opinion of experts on this also.
TIA
The framework already comes with a C# compiler you can use at execution time via CSharpCodeProvider.
You might want to look at the source code to Snippy, a small tool I wrote for C# in Depth - that compiles code on the fly, and can act as a reasonably simple introduction to CSharpCodeProvider.
I think I'd look at a scripting solution here; probably IronPython is the easiest to bundle and host, but others are available (including Javascript.NET, IronRuby, IronScheme, Boo, F#, etc)

Is anyone on the site in the beta for MonoTouch? What issues have you been seeing with it?
I personally have found it a very nice little system and have just made a small test app with it. The test app seems to startup slowly, but it works on my device so I am happy to be using C# on the iPhone.
If you have access to the monotouch mailing list you will find lots of useful information.
I for one found a couple of issues, mainly with the Interface Builder generating the C# code.
another one was an issue with MapKit where the app crashes.
Constant conversation on issues and ways to work around it are in the list and in #monotouch on the GIMP irc network.
Monotouch:

https://itunes.apple.com/au/app/conqueror-for-ipad/id606816778?mt=8&uo=44
It's also using ZXing.Net.Mobile.MonoTouch
I just loved it.
I don't know much about beta version. I bought the professional license and I am happy with that. It's impressive how fast I can get things running on C#. These 2 games are retina ready and optimized for iPhone 5.
