Structuremap Disposing of DataContext object

I wanted to be sure if structuremap will dispose my DataContext after per request ends.

Here is my setup

ForRequestedType<MyDataContext>().TheDefault.Is.OfConcreteType<MyDataContext>();
SelectConstructor<MyDataContext>(() => new MyDataContext());

Will structuremap auto dispose my datacontext or do i need to call Dispose manually??

That's what I do:

    For<IUnitOfWork>()
        .HybridHttpOrThreadLocalScoped()
        .Use<BpReminders.Data.NH.UnitOfWork>();

    For<ISession>()
        .HybridHttpOrThreadLocalScoped()
        .Use(o => ((BpReminders.Data.NH.UnitOfWork)o.GetInstance<IUnitOfWork>()).CurrentSession);

and ...

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

HybridHttpOrThreadLocalScoped uses the HttpContext when available.

StructureMap looks after everything, then. Just remember to implement IDisposable in your classes.

No it will not Dispose it automatically, unless you use nested containers and Dispose the container holding the context instance. It's up to the creator of the context to Dispose it. The creator would usually be the part of your code calling ObjectContext.GetInstance<MyDataContext> or the root method that makes StructureMap inject a DataContext into one of your objects.

A common practice is to create a context per HttpRequest and dispose the context at the end of the request.
