File->New Project.

Choose class library.

That's it.

No class library dll will let you do this, you need to expose an interface to your application. The only way I can see to talk to the instance that's running, is some sort of interprocess communication.

You don't understand my question...

I Create Program, Example rb.exe

I want that other persons create a .exe where can call functions like

RB.GetCurrentSong(); In the same machine and directory. Like in C++, where I can use Import and Export.

Thanks!

If I have to use a .dll no problem. :thumbsup:

OK, then a dll is exactly what you want to use, so that other people can use your code in their .NET program ( or use COM to be used by C++ and .NET programs ). But, that is not what you asked, you asked to run an exe and have people call that. If you want a dll, the answer I gave you is correct.
