Ninject.Web.Common throwing ActivationException trying to inject dependencies into HttpApplicationInitializationHttpModule

Question

I'm not sure where to even begin solving this, but I'm getting an exception when trying to run my ASP.NET MVC app.

Here is the error I'm getting:

[ActivationException: Error activating IntPtr

No matching bindings are available, and the type is not self-bindable. Activation path:

1. Injection of dependency IntPtr into parameter method of constructor of type Func{IKernel}
2. Injection of dependency Func{IKernel} into parameter lazyKernel of constructor of type HttpApplicationInitializationHttpModule
3. Request for IHttpModule

Suggestions:

1. Ensure that you have defined a binding for IntPtr.
2. If the binding was defined in a module, ensure that the module has been loaded into the kernel.
3. Ensure you have not accidentally created more than one kernel.
4. If you are using constructor arguments, ensure that the parameter name matches the constructors parameter name.
5. If you are using automatic module loading, ensure the search path and filters are correct.

The stack trace is as follows:

This doesn't seem to be an error everyone is getting (at least, my Google searches haven't turned up anything usefuL), so I assume I'm doing something odd, but I have no idea where to begin debugging this.

I should mention that I'm using several Ninject libraries (Ninject, Ninject.Web.Common, Ninject.MVC3, and Ninject.FluentValidation), all of which are version 3.0.00-RC3. I realize that all bets are off if I use pre-release libraries, but I have a feeling I'm doing something wrong because others don't seem to be getting the same error.

Any thoughts on what the problem could be or where I should start looking?

Answer 1

You can fix this by adding these two bindings to the kernel:

kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();
