You need to specify ContractNamespace on both assemblies to be the same.]]> Fri, 03 Dec 2010 02:22:42 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1944&PID=9303#9303 Error when attempting query to service from Silverlight : Hello, I'm facing exactly... http://www.ideablade.com/forum/forum_posts.asp?TID=1944&PID=9302#9302 Author: cdelbecq

I've resolved it - the problem I was specifying ContractNamespace on the .NET's assembly but not Silverlight's.

Hi

I have four projects - a .NET one for the model, and Silvelright one for the model (linking to the .IB.Designer.cs file), one for the Silvelright app and one for the web application.

It compiles OK, but when the client attempts a very simple query (return all entities - there's about 100 currently), I get the error below. It is similar to an error in http://www.ideablade.com/forum/forum_posts.asp?TID=1932 but I have checked my references against http://ideablade.com/Friends/FourProject.zip and it all looks in order.
