ASP.NET MVC 4 controller inheritance

Question

I have the following setup:
BaseController1 inherits System.Web.Mvc.Controller. This controller is compiled into a separate dll that is referenced from my project.
BaseController2 inherits BaseController1 in my project.
MyController inherits BaseController2.

When I run application with this setup, I get 404 error.

But if BaseController2 inherits directly System.Web.Mvc.Controller, and I run application with this setup, everything works as expected.

I have default constructor for all inherited controllers with : base() called.
The BaseController1 within assembly is compiled using references to asp.net mvc 3, and my project relies completely on asp.net mvc 4.

Can this be the problem? Or I am doing something wrong.

Thanks in advance!

If you debug through it, what's the actual error that's generating the 404? Do you have a stack trace or exception occurring? — Brad Christie

You're doing nothing wrong, but you will have to make MVC look in the specific assembly/namespace:

ControllerBuilder.Current.DefaultNamespaces.Add(
    "ExternalAssembly.Controllers");

This has already been answered in this question: asp.net mvc put controllers into a separate project

You pointerd me in right direction. The solution was to set 'Specific Version' to false under properties for System.web.mvc dll in Visual Studio. Thanks!
