Check out this C++ project that should do what you’re asking for.

You’d just set up your shortcuts to launch that app, which would in turn launch your .net app.

From the project description:

For example (test for a minimum of FW 1.1 and launch an application):

dotNetTester.exe 1.1 C:\Temp\Myapp.exeC:\Temp\Myapp.exe
