I know the use of WCF in SA is deprecated because it will move to SA Contrib. But until it has, I guess I have to use the support in SA. That said, I have a problem with the underlying NHibernate session being closed after calling a WCF service. My repository's DbContext.Session is closed after the first call so I cannot call my service...

When I develop ASP .NET I dont catch the majority of exceptions, I leverage Application_E...
