I have a WCF service. I have a problem with it.
Whenever I call a method with large response data (e.g: GetUserByUsernameWithAllRelations()) from service (with WCF Test Client) the following error occurred.
An error occurred while receiving the HTTP response to http://localhost:17497/SmartService.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
Server stack trace:

But if I call a method with a small response data (e.g: GetAllUsersCount()) it works without any problems.

P.S:
Here, in our company, we have a proxy in our windows to use LAN and the Internet. I disabled it but nothing changed.
Edit:
WCF Test Client Error:
Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service.
After couple of hours searching I could found the solution:
http://sanderstechnology.com/2013/more-with-the-entity-framework-v6-rc1/12423
I had to add [DataContract(IsReference = true)] attribute to each entity.
In above link you can learn how to do it with T4 in EntityFramework
