FluentNHibernate and Not Recognizing the Session - nhibernate

Question

For some reason the Nhibernate is chocking out when I try to access the session. It is throwing the following exception:
No CurrentSessionContext configured (set the property current_session_context_class)!
Please note I am not using XML to setup the configuration!
I am opening the session in my test:
[SetUp]
public void Initialize()
{
_session = GetSessionFactory().OpenSession();
_transaction = _session.BeginTransaction();
SetupContext();
When();
}
and then I am using Repository to access the current session. The repository is in different dll.
public void Save(Category newCategory)
{
var session = SessionFactory.GetSession();
session.SaveOrUpdate(newCategory);
}
public static ISession GetSession()
{
var session = _sessionFactory.GetCurrentSession();
if (session == null)
return _sessionFactory.OpenSession();
return session;
}
UPDATE:
In my BaseTest.cs class I also have a teardown:
[TearDown]
public void CleanUp()
{
_session.Dispose();
_transaction.Dispose();
}
During debugging it seems like the CleanUp is being fired and killing the _session object!
Another update: I have added the following code when building the configuration:
public static ISessionFactory CreateSessionFactory()
{
_sessionFactory =
Fluently.Configure().Database(
MsSqlConfiguration.MsSql2000.ConnectionString(
c => c.FromConnectionStringWithKey("ConnectionString")))
.Mappings(m =>
m.FluentMappings.AddFromAssemblyOf<Category>())
**.ExposeConfiguration(x =>
{
x.SetProperty("current_session_context_class",
"thread_static");
})**
.BuildSessionFactory();
return _sessionFactory;
}
Now I get the following error:
No session bound to the current context

Answer 1

You need to bind the session to the current context.
In the setup method:
var session = SessionFactory.OpenSession();
CurrentSessionContext.Bind(session);
And in the teardown method:
var session = CurrentSessionContext.Unbind(SessionFactory);
session.Dispose();
