Problem

I'm getting this error as my project is not able to find the reference for `OWIN` startup class. I've even installed all the OWIN reference packages through Nuget still getting the same issue. I'm using `Visual Studio 2012` and `MVC4`. The following errors occurred while attempting to load the app. - No assembly found containing an OwinStartupAttribute. - No assembly found containing a Startup or [AssemblyName].Startup class. To disable OWIN startup discovery, add the appSetting owin:AutomaticAppStartup with a value of "false" in your web.config. To specify the OWIN startup Assembly, Class, or Method, add the appSetting owin:AppStartup with the fully qualified startup class or configuration method name in your web.config.
