How to? what components do i need to have(platform builder?) ?
Please be as clear as possible - I find that this subject is very hazy and most people just give you a very vague answer.
I am running WInCE 5.0 with CF .net 2.0
Ultimately I need to create a self-updating application but I am going to start with creating a cab installer package.
You can create a cab file using the appropriate project type in Visual Studio. In Visual Studio 2005 select "Other Project Types", "Set up and deployment", "Smart device CAB project".
In a CAB file you can include executable and resource files. You can instruct where these files should be copied to. You can also add registry keys.
