WCF RIA service

having the following issue with newly created RIA service:

system.servicemodel.domainservi开发者_如何学Goces.client.Domainoperationexception: 
load operation failed for query 'GetUser'.

Why did the project automatically inlude the UserRegistrationContext service anyway? Can anyone please help?

I have seen this issue many times and there are so many reasons for the same. Secondly as soon as you create RIA service, VS automatically generate the proxy code in SL application. You can find the proxy code under generatedcode folder in your solution.
