You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You need to host the service in a medium trust environment on a Web server.
Which two bindings should you use?
(Each correct answer presents a complete solution. Choose two.)

A.
NetMsmqBinding

B.
BasicHttpBinding

C.
WSDualHttpBinding

D.
NetTcpBinding

E.
WebHttpBinding

Explanation:
The BasicHttpBinding and WebHttpBinding are fully supported in a partial trust environment. The WSHttpBinding is supported for Transport security mode only.

Bindings that use transports other than HTTP, such as the NetTcpBinding, the NetNamedPipeBinding, or the NetMsmqBinding, are not supported when running in a partial trust environment.
