How to use NInject with ASP.NET Web API on an OWIN Stack.
The project contains a configuration and various tests to cover the folllwing special cases. The goal is to easily understand how NInject needs to be configured to achieve the following goals:
- One Instance per Request
- Same instance used even if different interfaces are requested
Please use the latest Version of Ninject.Web.WebApi, See: http://stackoverflow.com/questions/28711963/ninject-activationexception-thrown-only-on-first-web-request-webapi-2-own-3-n

There are at least two known bugs related to this setup. See the following articles for details
- Incorrect implementation for WebApi with Owin (ninject/Ninject.Web.WebApi#22)
- OWIN in RequestScope (ninject/Ninject.Web.WebApi#23)
If this situations also apply to your project, I hightly recommend to not use the setup from this repository
