Yes, you can :-).
What you can't is mixing different machines.

Your PC with an Intel processor and Windows is a different machine
than the .NET virtual platform, with MSIL as machine code.
If you compile a module with language X into machine code for machine
A, and another module with language Y into another machine code,
machine B/=3DA, you won't be able to make both work together.
For instance you won't make a Commodore 64 machine code and a PC
machine code work together.
Perhaps if you think to a Commodore 64 emulator instead of the .NET
platform, it will be clearer.
So you need to find a common machine for compiling both languages.
For C#, only one choice: MSIL
For Ada, you have plenty of choices: Windows&Intel32/64,
Linux&Intel32/64/..., MacOSX&PowerPC/Intel, JVM, MSIL, UNIX,
OpenVMS, ...
And, hurray, you realize there is one common target machine in the
list: MSIL.
So you have to use the GNAT-for-.NET, not the GNAT-for-Windows.

Got it ?
