I have a WCF service with LINQ, it works if I try to get date from one table, but when I try to get data from one more (related) table I get this error:

An error occurred while receiving the HTTP response to http://domain.com/MyService.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:

  • did you get any hints from the .svclog file.Also check this link: http://msdn.microsoft.com/en-us/library/ms187005(v=sql.105).aspx – Saravanan May 26 '13 at 10:13
  • Just a thought if you are doing something similar http://consultingblogs.emc.com/merrickchaffer/archive/2007/09/19/WCF-System.Net.WebException_3A00_-The-underlying-connection-was-closed_3A00_-The-connection-was-closed-unexpectedly.aspx – S.N May 26 '13 at 10:22
  • try enabling tracing and check the actual error from svclog file try this link http://stackoverflow.com/questions/16679104/trace-wcf-call-from-client/16715631#16715631 – CSharped May 26 '13 at 15:36
  • Take a look at your code in `MyServiceClient.RecipeCategoryList()` - that's where the exception was thrown. Chances are good that you had an error in that operation that was not handled. – Tim May 27 '13 at 06:09
