A storage mechanism has already been configured for this application

I am getting this error whenever my S#arp Architecture attempts to start and this is an problem with SQL Server (for example: SQL Server is not runing), af开发者_运维问答ter I start SQL Server and hit refresh, I get this error:

A storage mechanism has already been configured for this application

---

NHibernateSession.Init() or InitStorage() is being called more than once. You're probably calling it every request, it's supposed to be called only once at startup.

---

In an old application I have to maintain, this happened when the application start had issues. So I just had to recycle the application pool in IIS.

Try to add this line before calling NHibernateSession.Init() to clear any previous initiation.

try{ NHibernateSession.Reset(); } catch { }
