WCF cannot work well when upload to the server

I have written a WCF to use data from a Sql server with an ADO.NET entity. It runs well on a local machine. However, when I have deployed on a server, the very same service gives me an error.

An unhandled exception of type 'System.ServiceModel.FaultException`1' occurred in mscorlib.dll

Additional information: Could not load type 'System.Reflection.IntrospectionExtensions' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

Any help would be appreciated.

You are most likely building your WCF service using .Net 4.5 and the server only has 4.0 installed.

Try changing your WCF service to use .Net 4.0 and re-upload to the server.
