Question

How to register Controller in MVC3?

I have 2 solutions:

• MvcApplication (MVC 3 Web Application) with file ‘HomeController.cs’

• CustomController (Class library) with file ‘CustomController.cs’

If i Build ‘CustomController’ solution and Add reference in MvcApplication solution to this, i can simple use CustomController in application. But how i can do it without ‘Add reference’ action, just with Assembly.LoadFrom(PathToDll) e.t.c.?

Answer 1

You could use MEF for that.

See a good article

http://blog.maartenballiauw.be/post/2009/04/21/ASPNET-MVC-and-the-Managed-Extensibility-Framework-(MEF).aspx

This section in your global.asax, register the new controller fac and set the “Plugins” folder for MEF load their libraries. Plugins folder is in your asp.net app root folder.

ControllerBuilder.Current.SetControllerFactory( 
new MefControllerFactory( 
    Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Plugins")));
