Fluent NHibernate Configuration for Session Context

[Action Jackson]

I apologize in advance if this question has been answered many times
over. How can I specify the session context using the Fluent
configuration? In other words, what is the Fluent translation of a
traditional xml mapping like "<property
name="current_session_context_class">thread_static</property>"?

You set this on your NHibernate.Cfg.Configuration instance right?

You should be able to use the ExposeConfiguration method to get access to the underlying Configuration instance and then set the session context appropriately. Or alternatively you can build your Configuration instance as you normally would including setting the session context, and then pass it in as an argument to Fluently.Configure().

If you're using Fluently.Configure there's also a Raw method, which'll allow you to set any property that isn't already exposed.

Paul and James, thank you very much for your responses. I have
tried these approaches, but with no luck. I'm noticing an issue that
is very interesting. Hopefully, something jumps out at you right
away. Here's an example of the code which presides in a class I call
'NHibernateHelper' (borrowed from NH in Action):

_cfg = new Configuration()
.SetNamingStrategy( naming strategy class here)
.SetProperty("current_session_context_class",
"thread_static");

// NOTE: At this point, the _cfg configuration object has 8 properties
including the current session context setting. The interesting part
comes next:

_sessionFactory = Fluently
.Configure(_cfg)
.Database
(
MsSqlConfiguration.MsSql2005
.ConnectionString(c =>
c.FromConnectionStringWithKey("conn"))
)
.Mappings
(
x => x.FluentMappings
.AddFromAssembly(...blah blah blah...)
)
.BuildSessionFactory();

After executing this piece of logic, the number of properties of the
_cfg configuration object has been reduced from 8 to 5 and the session
context setting is gone. Consequently, a piece of logic like this
fails since there is no session context:

try
{
using (ISession session =
NHibernateHelper.GetCurrentSession())
{
using (session.BeginTransaction())
{
CurrentSessionContext.Bind(session);

session.Save(person);
}
}
}
finally
{
CurrentSessionContext.Unbind
(NHibernateHelper.SessionFactory);
}

Any ideas? Thanks again for your help thus far!

Did you try ExposeConfiguration like this ?

_sessionFactory = Fluently
.Configure(_cfg)
.ExposeConfiguration(c=>c.SetNamingStrategy

( naming strategy class here)

.SetProperty("thread_static");

Hey, thank you very much for your response. However, your
suggestion to use ExposeConfiguration() doesn't seem to be working
either. I've tried variations of potential solutions that use
ExposeConfiguration(). Still no luck. Would you be kind enough to
provide the full block of code that works for you? I'm still noticing
the "property count reduction".

Actually, after several tweaks, I think I finally got it. Here's what
I came up with:

_sessionFactory = Fluently
.Configure()
.Database
(
MsSqlConfiguration
.MsSql2005
.ConnectionString(c => c.FromConnectionStringWithKey
("conn"))
)
.Mappings( x =>
{
x.FluentMappings
.AddFromAssembly(Assembly.LoadFrom(blah blah...))
.ConventionDiscovery.AddFromAssemblyOf<blah blah...>();
})
.ExposeConfiguration( x =>
{
x.SetProperty("current_session_context_class",
"thread_static");
})
.BuildConfiguration()
.BuildSessionFactory();

It's all clear to me now...thank you to all that replied. Hopefully,
this post helps others out there.
