Why is my Castle Windsor controller factory's GetControllerInstance() being called with a null value?

Question

I am using Castle Windsor to manage controller instances (among other things). My controller factory looks like this:

public class WindsorControllerFactory : Def         


        

Answer 1

regarding registration of all the controllers you'd usually do it like this:

container.Register(
   AllTypes.FromThisAssembly()
      .BasedOn<IController>()
      .Configure(c => c.Lifestyle.Transient)
);

See the documentation for more explanation of the API.

Answer 2

Had this problem when following the Pro ASP.NET MVC Framework book, added

routes.IgnoreRoute("favicon.ico");

to the routes in the global.asax.cs file and it works. See more here: serving favicon.

Answer 3

Very late addition: The step-by-step tutorial at the windsor site seems good. It breaks down the creation of a controller and how it's loaded into the factory. It also covers the "favicon.ico" noise.

Answer 4

It turns out that the second request was the MVC framework trying to find a script I included in the Site.Master. The path did not exist, so I guess it tried to resolve a controller (that matched /Scripts/sitescripts.js). I changed the method to this:

protected override IController GetControllerInstance(Type controllerType)
{
    if (controllerType != null)
    {
       return (IController)_container.Resolve(controllerType);
    }
    else
    {
       return base.GetControllerInstance(controllerType);
    }
}

And an exception with an understandable message was thrown.
