NHibernateSagaPersister and session context

Hi Diego

Unfortunately the version of NServiceBus you are referring to is no longer supported. I did a quick glance through the code though and it seems it was hardcoded

github.com

Particular/NServiceBus/blob/2.0/src/impl/SagaPersisters/NHibernateSagaPersister/NServiceBus.SagaPersisters.NHibernate.Config/Internal/SessionFactoryBuilder.cs#L72


      
          

              new SchemaUpdate(configuration)

                  .Execute(false, true);

          }

          

          private static void ApplyDefaultsTo(FluentConfiguration fluentConfiguration)

          {

              fluentConfiguration.ExposeConfiguration(

                  c =>

                      {

                          c.SetProperty("current_session_context_class",typeof(ThreadStaticSessionContext).AssemblyQualifiedName);

          

                          //default to LinFu if not specifed by user

                          if (!c.Properties.Keys.Contains(PROXY_FACTORY_KEY))

                              c.SetProperty(PROXY_FACTORY_KEY,typeof(ProxyFactoryFactory).AssemblyQualifiedName);

                      }

                  );

          }

I can only imagine it is because for the message handling pipeline ThreadStaticSessionContext was the only context that made sense because a message was handled on a dedicated thread. Therefore session context would not overlap. To me it seems the WebSessionContext only makes sense when using a web application to send messages but not receive them.
