@Dhananjay Please make sure you are deploying to the correct device and your device should be connected to the computer correctly.

For more information follow this article, check point 14: Create a new VCsharp project

Also, are you able to deploy any console application to the Colibri device ? If not can you try to do that first.
Check this article for more information: Create a new VC++ project

Note: Make sure you have uncheck “Deploy the latest version of the .Net Compact Framework” option.
(Project Properties > Devices), if not then please do it first and then try to deploy your project.

Thanks Rajat for your quick response.
Any application developed in VC# is not working while VC++ console application is running fine

and when uncheck “Deploy the latest version of the .Net Compact Framework” option application showing deployed successfully in Visual Studio but nothing is happening when open from Colibri windows

Are you sure you have installed .Net CF 3.5 in your Colibri Device ?
I asked the same question on our telephonic discussion , you said Yes.
Please confirm whether you have installed .Net CF 3.5 in your device.

@Dhananjay: Can you please confirm again whether you have installed .NET CF 3.5 in your Colibri device or not ?
If you have not installed, then please do it first and then try to run your application.

I have tried with a simple application and its working fine, Thanks Rajat for your kind support.
