Can a dynamic proxy be used as a controller?

For fun, I thought I'd try this out:

public class RouteConfig
{
    public static void BuildProxy()
    {
        AssemblyName dynasm = new AssemblyName("Dynasm");
        AssemblyBuilder asmBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly(dynasm, AssemblyBuilderAccess.Run);
        ModuleBuilder modBuilder = asmBuilder.DefineDynamicModule(dynasm.Name);

        TypeBuilder typeBuilder = modBuilder.DefineType("MyProxyController");
        MethodBuilder action = typeBuilder.DefineMethod("Action", MethodAttributes.Public, CallingConventions.Standard,
            typeof(String), Type.EmptyTypes);

        ILGenerator ilGen = action.GetILGenerator();
        ilGen.Emit(OpCodes.Ldstr, "The value to return");
        ilGen.Emit(OpCodes.Ret);

        Activator.CreateInstance(typeBuilder.CreateType());
    }

    public static void RegisterRoutes(RouteCollection routes)
    {
        BuildProxy();

        routes.AppendTrailingSlash = true;
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute("Proxy", "Proxy/Action", new { controller = "MyProxy", action = "Action" });

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
}

The idea is basically to generate a class at runtime, and use it as a controller. For some reason though, When I navigate to /Proxy/Action the routing engine doesn't seem to see my class. Why is that?

The MVC route engine looks for Controller classes to route the request to the correct place.

You should implement an IRouteHandler interface for this one instead! Here's a dummy example just for you start Routing for Proxy
