Yet another to manage your NHibernate isessionfactory

So here's my current unitofwork implementation. This one makes use of the somewhat new current_session_context_class feature. I think this was quite simple compared-some of the others you'll find.

Interface iunitofwork:idisposable    {        iunitofwork Start ();        void BeginTransaction ();        void CommitTransaction ();        void RollbackTransaction ();    }  

PublicClass Unitofwork:iunitofwork {#region DependenciesPublic isessionfactory sessionfactory {get;        Set }#endregion#region Iunitofwork MembersPublicVirtualvoid BeginTransaction () {var session = Sessionfactory.getcurrentsession ();if (!session. Transaction.isactive) {session. BeginTransaction (); } }PublicVirtualvoid CommitTransaction () {var session = Sessionfactory.getcurrentsession ();if (session. transaction.isactive) {session.Transaction.Commit (); } }public void rollbacktransaction () {var session = Sessionfactory.getcurrentsession (); if (session. Transaction.isactive) {session. Transaction.rollback (); }} public iunitofwork Start () {if (! Currentsessioncontext.hasbind (sessionfactory)) {var session = Sessionfactory.opensession (); session. Flushmode = Flushmode.commit; Currentsessioncontext.bind (session); } return this;}  #endregion  #region IDisposable members public void Dispose () {var session = Currentsessioncontext.unbind (sessionfactory); var transaction = session. Transaction; if (transaction. IsActive) {transaction. Dispose (); } session. Dispose (); }  #endregion}            

All of that ' s required are this in the Hibernate config section:

(for Web Apps):

<name= "Current_session_context_class">web</Property>   

(For pretty much anything else):

<name= "Current_session_context_class">thread_static</Property> 

And just the barebones bootstrapping:

New Configuration (). Configure (). Buildsessionfactory ();            

Of course, to-get this-to-work-need to register that sessionfactory instance into your IoC container, and register the Unitofwork type with the container with a transient lifecycle.

From there you can either explicitly create and Dispose iunitofwork instances for each operation, or set up a HttpModule t o Create one at the start of each request and dispose of it in the End_request event.
