by

For info: It is possible to register the kernel as a singleton so that the same kernel can be used by the ninject middleware and also registered within the owin context. public static StandardKernel CreateKernel() { if (_kernel == null) { _kernel = new StandardKernel(); _kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>(); _kernel.Load(Assembly.GetExecutingAssembly(), Assembly.Load(“Super.CompositionRoot”)); } return _kernel; } The callback function … Read more

Global exception handling in OWIN middleware

by

Ok, so this was easier than anticipated, thanks for @Khalid for the heads up, I have ended up creating an owin middleware named OwinExceptionHandlerMiddleware which is dedicated for handling any exception happening in any Owin Middleware (logging it and manipulating the response before returning it to the client).
