Hi I have a silverlight4 + .net 4.0 application where i am using self tracking entities. In the application i have a silverlight project which contains the entities generated by EF self tracking template. This project is being shared by the wcf service and the client so that the change tracking works. everything builds fine but when i run my service is get the exception Could not load file or assembly 'System.Runtime.Serialization, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified.
any help is much appretiated
thanks Ben
