I was surprised to find that at least one of my objects created by Ninject is not disposed of at the end of the request, when it has been defined to be InRequestScope
<Ninject will dispose your objects as soon as the request object is collected by the GC. But normally this takes some time. But there is a way to force early disposal after the request ended. The best way is to use Ninject.Web.MVC http://www.planetgeek.ch/2010/11/13/official-ninject-mvc-extension-gets-support-for-mvc3/ instead of implementing your own ControllerFactory. The other way is to configure your application to use the OnePerRequestModule.
