Hi
I tried to write a task manager by using Thread class and NHibernate , but I got the following exception.
I also remove isWeb="true" from facilities.config.
Sample Code:
private Article _article;
private ArticleModule _articleModule;
private void StartTask()
{
Thread thread = new Thread(new ThreadStart(Execute));
thread.Start();
}
private void Execute()
{
try
{
this._article = this._articleModule.GetArticleById(articleId);
// ...
}
catch
{
}
}
Exception error
Castle.MicroKernel.Facilities.FacilityException was unhandled

When performing things in a separate thread, you have to obtain a session manually because as if you have noticed, there is no HttpContext where the session manager retrieves its session from (don't remove isWeb from the config). In your module: Code:
private void Execute()
{
ISessionFactory sessionFactory = IoC.Resolve< ISessionFactory >();
using (ISession session = sessionFactory.OpenSession())
{
MyObject myObject = session.Get< MyObject >(objectId);
...
}
}
See also the RemoteContentModule.cs (FetchFeed()).

Hi guys,
Forgive the late post, I am playing with the 2 beta and implemented as simular task archetecturem and was wondering how you would do the same, as a lot of the SessionFactory code was replaced with the SessionFactoryHelper and the ISessionManager?
