Created an attachment (id=416679)
 --> (http://bugzilla.novell.com/attachment.cgi?id=416679)
Zipped VS2010 test project that contains 3 projects

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US)
AppleWebKit/534.13 (KHTML, like Gecko) Chrome/9.0.597.98 Safari/534.13

I created a simple .Net 4 WCF service in VS2010. It contains one method called
"Ping" which return a string "Pong". A VS2010 client WPF application hits the
service and it works fine, the string "Pong" is returned. I then created a
MonoDroid Application to hit the same service. Everything compiles fine but
when I call the Ping method I get an error.

Reproducible: Always

Steps to Reproduce:
1. Make a client call to a WCF service.

Actual Results:  
Following error is raised

System.TypeLoadException: Could not load type '__clientproxy_IService1' from

Expected Results:  
The call made to the service and a string "Pong" returned.

I have tried both synchronous and asynchronous calls to the service with the
same error being raised. The error is raised on both the Android emulator and
my HTC desire device. 

I could ping the computer the service is hosted on using a 3rd party ping
application I downloaded from the actual Android device.

I have included a VS2010 Solution with 3 projects.
The WCFService, WPFClient, MonoDroidClient
