Error: This module requires Ninject.Web.WebAPI extension - asp.net-mvc-5

Question

I'm using Ninject.Web.WebApi.OwinHost v3.2.4 and I get this error the first time you hit a page. Then it works from then on:
This module requires Ninject.Web.WebAPI extension
The stacktrace is:

How do I fix this?

Answer 1

This occurs when you create your kernel without scanning the DLLs for Ninject modules, for example:
var kernel = new StandardKernel(new NinjectSettings
{
LoadExtensions = false
});
The way to fix this is to manually load the modules that Ninject.Web.WebApi.OwinHost needs
kernel.Load(typeof(Ninject.Web.WebApi.WebApiModule).Assembly);
