I'm using MVC 4 and Ninject 3 with NinjectWebCommon in the App_Start folder.
And my Global.asax.cs is MvcApplication : HttpApplication
I'm getting the error below because the Ninject is starting twice - Why?
Server Error in '/' Application.

This was caused when I refactored the namespaces and binary name.
This meant that a old copy of the dll with the old name was still in the bin folder.
Which meant both dll's were being activated at start up.
A Clean did not remove it, so I deleted manually and the problem went away.
I came across this issue and spent a couple hours trying various recommendations on the internet. The thing which fixed it in the end was to check for circular references across namespaces in my project. Have a look at your .csproj files and check all the references are correct
