WCF Timeout problem

Mark Sutton posted on Thursday, October 06, 2011

From my Silverlight client I'm asynchronously calling a long-running stored procedure on the server (~25 mins). The problem I'm getting is a timeout exception at the client after 10 minutes.  

I've tried increasing the WCF client and server timeouts (receive, send, open, close) to 2 hours, but with no effect.  I'm also aware that the default inactivityTimeout for reliable sessions is 10 minutes, but I'm using BasicHttpBinding which doesn't allow reliable sessions.

I'm using CSLA 4.0.1

Can anyone shed some light on this?

 

Error:

 

System.Exception: Error Executing Calculation ---> System.Exception: Error Executing Calculation ---> Csla.DataPortalException: The HTTP request to 'http://applicationname/WcfPortal.svc' has exceeded the allotted timeout. The time allotted to this operation may have been a portion of a longer timeout.

                    {

                        throw new Exception("Error Executing Calculation", e.Error);

                    }

                    else

                        RunName = result.RunName;

                    }

                };

                dp.BeginExecute(command);

I've found the answer.  The CSLA class Csla.DataPortalClient.WcfProxy has a DefaultBinding property with default timeouts of 10 minutes.  

These values can be re-set in the Silverlight client.
