Simple code example to reproduce problem.

Description of Problem:
Can't enable WCF discovery using mono framework. I was following http://msdn.microsoft.com/en-us/library/dd456791.aspx example to test feature. That example works using .NET framework, but fails with mono framework. The problem is in line where is UdpDiscoveryEndpoint added. I'am getting exception:

   Contract 'TargetService' is not implemented in this service 'testService'

Steps to reproduce the problem:
I'am adding attachment with test code.

Actual Results:
Exception.

Expected Results:
Enables WCF discovery on Linux machine(mono) and could be discovered using DiscoveryClient class in windows machine(.NET).

How often does this happen? 
Always

Additional Information:
Using latest mono framework package(mono 3.0.7-1) from Arch linux repositories.
