问题

I'm having an huge problem with the my web service.

When I try to generate the files via svcutil I get the following error messages:

Attempting to download metadata from 'http://srv:13208/GROUPING_WS_ASMX.as
mx' using WS-Metadata Exchange or DISCO.

Any help will be much appreciated.

Turns out that Silverlight does not like the XHttpPost biding.

So I remvoed this binding in my web.config from the web service and all is up an running.
