[Mono-list] A Plugin and WebService Issue

[Rob.Tillie@Student.tUL.EDU]

I don't fully understand you.
If you require that any plugin implements your interface ( which should =
have
those methods of you like Post etc.) then you're fine.
What else should you want then?

Sure,

I'd like to be sure that the plugin of the user has a 'Post' method for
example, or a 'DeletePost', if all the 'rules' are ok the code will be
compiled with an AssemblyInfo.

I know that I can verify if the method exists invoking it and if I get
Null there's no method, but I'd like to do this also in the compilation
process.

See ya!
