Hello,

I'm trying to install the colleague viewer/social networking webpart, but am getting an error:

Silverlight BluePrint for SharePoint: SilverLight 2 Colleague Viewer Web part: Could not load file or assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

No clue as to what this means. Is there any other pre-requisite files needed? How can I correct this?

MOSS 2007, SP1 not installed yet..

Thanks,

Brian

Have you been through all the post BluePrint sample stuff, on Patrick Tisseghems Blog [ http://www.u2u.info/Blogs/Patrick/Lists/Categories/Category.aspx?Name=Silverlight%20BluePrint ], This includes major Web.config segment swaps, etc

He has a Video illustraing how to get Silverlight 2.0 Up and going on SharePoint.  Rather more involved that teh BluePrints would have us believe.
