{"This operation requires IIS integrated pipeline mode. - Nhibernate

[Ashwin]

I started using NHibernateSessionPerConversationModule.cs HttpModule
(http://www.summerofnhibernate.com/ ) which creates a session per
conversation ( and everytime there is a page request for some reason
the Application_BeginRequest gets fired twice. And it ends up throwing
the follwoing messages.

1) Object reference not set to an instance of an object.

When I dig deeper here is what i see in the follwoing error messages

base {System.NotSupportedException} = {"This operation requires IIS
integrated pipeline mode."}

CurrentNotification = 'HttpContext.Current.CurrentNotification'
threw an exception of type 'System.PlatformNotSupportedException'

Iam using Visual studio 2008 on my windows 7 laptop and IIS server
( Version 7.5.7600.16358 ) . Am not sure if I have to change any
settings in the integrated webserver of VS 2008.

Here is the code.

private void Application_BeginRequest(object sender, EventArgs e)
{
ISession currentSession =
(ISession)HttpContext.Current.Session[NHIBERNATE_CURRENT_SESSION_KEY];
if (currentSession == null)
{
currentSession = StaticSessionManager.OpenSession();
currentSession.FlushMode = FlushMode.Never;
}
CurrentSessionContext.Bind(currentSession);
currentSession.BeginTransaction();
}

private void Application_EndRequest(object sender, EventArgs
e)
{
ISession session =
CurrentSessionContext.Unbind(StaticSessionManager.SessionFactory);

if
(HttpContext.Current.Items[NHIBERNATE_CONVERSATION_END_FLAG_KEY] !=
null)
{
session.Flush();
session.Transaction.Commit();
session.Close();

HttpContext.Current.Session[NHIBERNATE_CURRENT_SESSION_KEY] = null;
}
else
{
session.Transaction.Commit();

HttpContext.Current.Session[NHIBERNATE_CURRENT_SESSION_KEY] = session;
}

}

Just change the app pool in IIS to use the Integrated Pipeline instead of the classic pipeline. This also may necessitate some changes to your web.config file as well (adding a webserver section and moving the modules under there IIRC).
