Ninject MVC3 leads to "cannot find file Mvc.sitemap"

Question

I am trying to use Ninject on a Web project. In Visual Studio I ran

Install-Package Ninject.MVC3

But now when I run the project I get the error

Could not find file '<path>\Mvc.sitemap'

What is this Mvc.sitemap file?

Answer 1

Managed to resolve the problem by installing:

Install-Package MvcSiteMapProvider.MVC5

Still don't quite understand why Ninject depends on SiteMap.
