I am making an WP7 app that connects to SQL DB through WCF. But after adding the client proxy and testing it, I got this error.
The type or namespace name IExtensibleDataObject does not exist in the namespace System.Runtime.Serialization (are you missing an assembly reference?)
Apparently (and according to this blog), the .NET Compact Framework used by WP7 does not expose IExtensibleDataObject in the
System.Runtime.Serializationnamespace.An alternative is to use the Silverlight Service Model Proxy Generation Tool to generate the client proxy. The resulting code should work on WP7.
