I installed CSLA 3.5 and the Project Tracker sample application on Windows Server 2008 with IIS 7 and Microsoft SQLExpress. When I executed the Windows Forms application I would get this error trying to load WCF:
TCP error code 10061: No connection could be made because the target machine actively refused it
After several hours of fooling around with the security and setup of IIS 7.0, I discovered that I was actually SQLExpress that was causing the error becuase the TCP protocol is off by default. When I turned it on in SQL Server Configuration Manager, the application was able to come up without incident. I just wanted to post this here as a solution to this error in case other people run into the same problem.
