Sorry I didn't read all your post.

So I compiled the stub into a dll, created my asmx.
When i try to access the General.asmx, i get an error :

*Description: *Error processing request.

*Error Message: *HTTP 500.

*Stack Trace: *

Any idea ?
I don't compile from svn, i'm using 1.1.8.20050824. My admin would 
complain if i svn the mcs tree.
I can't use the latest release because the datagrid buttoncolumn is broken.

Thanks,
Johann
