Question

I’m working on an asp.net-mvc application. The linq data context is being passed into my service objects by structure map. I’ve got is set to have a scope of hybrid. This all works just fine.

protected override void configure() {     ForRequestedType<AetherDataContext>()         .TheDefaultIs(() => new AetherDataContext())         .CacheBy(InstanceScope.Hybrid); } 

The problem is that I keep running our of memory, I’m wondering if the IDisposable interface is ever actually being called.

Anyone got any ideas?

Failing that anyone got any other idea for things that might be causing my memory exceptions?

Update:

So some additional information, I just stuffed a couple of methods into my data context an put brake points in there.

protected override void Dispose(bool disposing) {     Debug.WriteLine('Disposing: ' + DateTime.Now);     base.Dispose(disposing); }  public new void Dispose() {     Debug.WriteLine('Disposing: ' + DateTime.Now);     base.Dispose(); } 

I’m not quite sure that I’m doing this the correct way, I’m guessing that the new method will be called?

Anyway, neither of the brake points were hit. However the constructor for the same class was called on every request though. Not ideal I’m thinking.

This is almost an exact copy of the question I asked 2 days ago: Session containing items implementing IDisposable

InstanceScope.Hybrid just stores the object inside HttpContext.Current.Items if it exists or ThreadLocal storage otherwise and InstanceScope.HttpSession works the same way other than it uses the HttpSession and ThreadLocal. The items collection lives per request, so if you implement the pattern pointed out on my question you should see Dispose firing at the end of the current request.
