Apparent errors when referencing Silverlight class libraries

Hi

I really like solution wide analysis but it does continually complain about the fact I am referencing Silverlight assemblies in my WCF project and its support classlibraries.  It is suggesting that I reference the Silverlight version of System (which isn't possible and isn't necessary).  I can't seem to find a way of suppressing this error either so I just have to hunt through to find out if there are actually any problems with the files.

Regards

Mike
