ASP.NET MVC 3, RavenDB, & Autofac Issue Plus 2 Other Autofac Questions

Question

NOTE: There are 3 questions in here and I did not make separate questions since they are all somewhat related to the same code.

I have the following

Answer 1

I'm guessing you want something like:

builder.Register(c => c.Resolve().OpenSession()).InstancePerLifetimeScope();

"The default ASP.NET and WCF integrations are set up so that InstancePerLifetimeScope() will attach a component to the current web request or service method call." - Autofac: InstanceScope

Basically, in a web app, InstancePerLifetimeScope handles the one per HTTP context aspect, and also disposes any types that implement IDisposable.
