Ok ok, sorry ;-)

If I want to create a plugin, I should generate the wsdl code of my
webservice (SOAP) then compile it as a library.. this library is the
plugin.

What I'm looking for is that, when the user tries to make it library,
the user should compile it with a resource or another library. The
resource SHOULD look in the code before making it a library.

What SHOULD look in the WSDL code?, methods, so the resource should look
if the WSDL code has a : Post method, a DeletePost, etc. if these
methods are ok, then make it a library with some AssemblyInfo.
