It goes into a DLL once compiled, but it's in a code file when added to the project (referred to as a proxy class, it's in whatever language your project is). When you add a web reference it's imported this way. Updating the reference updates the .cs (or vb, whatever you're using).

If you want to see what happens, you can generate the code file yourself, see MSDN for details.

So overall: It is WSDL when fetched, converted to a code file when included (or updated), then finally compiled with the rest of your code into the DLL.
