you missing reference system.runtime.serialization (.net) assembly. add together project reference , should good.

you can see in documentation (msdn), datacontractattribute, extensiondataobject , iextensibledataobject defined in system.runtime.serialization.dll assembly.

http://msdn.microsoft.com/en-us/library/system.runtime.serialization.datacontractattribute.aspx http://msdn.microsoft.com/en-us/library/system.runtime.serialization.extensiondataobject.aspx http://msdn.microsoft.com/en-us/library/system.runtime.serialization.iextensibledataobject.aspx
