I created a binding for HttpContextBase in my NinjectWebCommon.RegisterServices method, but when I try to reference it in my controllers or services I get an error message.

Here's the binding:

kernel.Bind<HttpContextBase>().ToMethod(context => new HttpContextWrapper(HttpContext.Current)).InRequestScope();

Here's the error message:

Error activating HttpContextBase
More than one matching bindings are available.
Activation path:
 2) Injection of dependency HttpContextBase into parameter abase of constructor of type HomeController
 1) Request for HomeController

Suggestions:
 1) Ensure that you have defined a binding for HttpContextBase only once.

If I remove the binding, then it appears to do what I wanted (resolves to HttpContextWrapper), but I'm wondering how this gets registered?
