What about when I need to use specific lifetimescope within a using from a viewmodel? How can I do this without exposing the container? Or will I just have to?

using (var scope = Container.BeginLifetimeScope(“Commit”))
{
….
}

Good question. I don’t have an answer yet, but I will give it some thought. Can you provide a use case for this?

Well, in my case it’s for accessing my data layer services. I use the lifetimescope in this way to make sure I don’t have a constant open connection and instances of service classes open.

What I’ve done since this post was to expose the container property as public, and then in the GetInstance i added:

if (serviceType == this.GetType()) return this

That allows me to use IoC.Get().Container.BeginLifetimeScope

It’s the only thing i’ve come up with so far.

So i've since changed this. the first thing in the TYpedBootStrapper.GetInstance is now:

if (serviceType == typeof(ILifetimeScope))
{
if (string.IsNullOrEmpty(key))
return Container.BeginLifetimeScope();
return Container.BeginLifetimeScope(key);

        }

This then allows me to simply use:

IoC.Get("key")

to get my scopes.
