How do I use AutofacWebTypesModule to Resolve HttpServerUtilityBase

I have the following registrations

    builder.RegisterModule(new AutofacWebTypesModule());
    builder.Register<MyType>(ctx =>
    {
        var server = ctx.Resolve<HttpServerUtilityBase>();
        ...
    });

When I try to resolve MyType via a constructor on an Controller, I get the following exception. What am I doing wrong?

Autofac.Core.DependencyResolutionException was unhandled by user code

Message=No scope matching the expression 'value(Autofac.Builder.RegistrationBuilder`3+<>c__DisplayClass0[System.Web.HttpServerUtilityBase,Autofac.Builder.SimpleActivatorData,Autofac.Builder.SingleRegistrationStyle]).lifetimeScopeTag.Equals(scope.Tag)' is visible from the scope in which 开发者_Python百科the instance was requested.

Yikes - that error message has gone all wrong :)

The problem is most likely that you're trying to resolve MyType directly from the container (as opposed to the DependencyResolver or else you're taking a dependency on it from a singleton. The HttpServerUtilityBase component can only be used in the context of a web request.

Trying to resolve it from Applicaiton_Start will also fail in IIS7 integrated pipeline mode.

HTH! Nick
