No scope with a Tag matching 'AutofacWebRequest' is visible...

[Tim Schmidt]

I have what I believe is a fairly MVC4 project (it technically has WebAPI although I'm not currently using it at all).  Everything works fine until I try to have an "InstancePerHttpRequest" component.  Then I get the dreaded:

No scope with a Tag matching 'AutofacWebRequest' is visible from the scope in which the instance was requested. This generally indicates that a component registered as per-HTTP request is being reqested by a SingleInstance() component (or a similar scenario.) Under the web integration always request dependencies from the DependencyResolver.Current or ILifetimeScopeProvider.RequestLifetime, never from the container itself.

And I can't figure out how to resolve it.  Everything works if I change the offending component to default lifetime scope.  I'm using the most recent versions of the Autofac and Autofac.Integration.Mvc4 packages.

Can anyone help?

Thanks,

tim

Hi Tim - is this happening as part of controller construction, or are you calling Resolve() somewhere, on something directly?

Cheers,

Nick

Thanks for getting back to me, Nick.  This is during controller construction.  Here's the full exception:

[DependencyResolutionException: No scope with a Tag matching 'AutofacWebRequest' is visible from the scope in which the instance was requested.
