Question

I want to use AutoFac to inject references into an object’s constructor. However, the actual object itself is not registered. I am doing this for an ASP.NET MVC controller factory, where the controller won’t be registered, but the constructor params will be. I managed to do this in unity, but I am having trouble with AutoFac.

Is that possible?

Thanks.

Answer 1

Autofac can’t resolve a type that hasn’t been registered, even when this type is concrete with a single public constructor.

In your situation this problem however can be solved easily, because there is an Mvc3Ingegration package for Autofac that contains a RegisterControllers extension method for the builder. You can use it as follows:

builder.RegisterControllers(typeof(MvcApplication).Assembly);
