Does StructureMap have scoping corresponding to NInject's DefinesNamedScope/InNamedScope?

Question

The problem I'd like to solve is sharing an ISessionProvider between IXyzRepositories (where ISessionProvider holds the current NHibernate ISession).

I'm tweaking the "Setting up session per presenter" recipe from NHibernate 3 Cookbook, and would like to keep StructureMap (brownfield project).

I think you would have to create a custom Lifecyle to do that, although I am not sure what exactly you are trying to accomplish...

To create a custom Lifecycle, you just have to implement the ILifecycle interface and the use it in your registration. Here is an example you can look at: http://blog.mikeobrien.net/2010/01/creating-structuremap-lifecycle-for-wcf.html.

Answer 2

In a web application I use Singleton for the sessionFactory and HybridHttpOrThreadLocalScoped for the session: This is my structuremap registry:

public class NhibernateRegistry: Registry
{
    public NhibernateRegistry()
    {
        For<ISessionFactory>()
        .Singleton()
        .Use(new NHibernateSessionFactory(connectionString).SessionFactory);

        For<ISession>()
        .HybridHttpOrThreadLocalScoped()
        .Use(o => o.GetInstance<ISessionFactory>().CurrentSession);
    }
}

My NHibernateSessionFactory is similar to SessionProvider class used in the book. Everything is disposed at the end of the request (web app):

protected void Application_EndRequest(object sender, EventArgs e)
{
    ObjectFactory.ReleaseAndDisposeAllHttpScopedObjects();
}

I use a generic repository:

public class GenericRepository<T> : IGenericRepository<T> where T : class
{
    private readonly ISession _session;

    public GenericRepository(ISession session)
    {
        _session = session;
    }

    public T Load(Guid Code)
    {
        return (_session.Load<T>(Code));
    }

}

but you can easily change it with your own implementation. I register the repository here:

public class RepositoriesRegistry : Registry
{
    public RepositoriesRegistry()
    {
        For <Data.IRepository<Domain.Reminder, Guid>>()
            .HybridHttpOrThreadLocalScoped()
            .Use<Data.NH.Repository<Domain.Reminder, Guid>>();
    }
}
