c# - MVC5 Redirects to Login.aspx when using Windows Authentication

Question

After upgrading from MVC 4 to MVC 5, my application (when started from within Visual Studio) gives the following error. It might also be worth noting that I am hosting both MVC5 and WebAPI2 items in the same project as there may be interference going on. I also installed the dotnetopenauth nuget package (which I have since removed):

Server Error in '/' Application.

The resource cannot be found.

Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is spelled correctly. 

Requested URL: /login.aspx

I'm not really sure why this is as there is no authorization attributes set in the filters or on the controllers.

Global.asax:

    public class MvcApplication : HttpApplication {

    protected void Application_Start() {
        IDependencyInjectionBuilder dependencyInjectionBuilder = new DependencyInjectorBuilder();
        var builder = new ContainerBuilder();

        builder.RegisterControllers(typeof(MvcApplication).Assembly);
        builder.RegisterApiControllers(Assembly.GetExecutingAssembly()); //For WebAPI dependency injection
        var injector = new AutofacDependencyInjector();
        dependencyInjectionBuilder.RegisterTypesAndInstances(injector, false, true);
        DependencyInjectionRegistration.RegisterServices(injector);

        builder.Update(injector.Container.ComponentRegistry);

        var autofacDependencyResolver = new AutofacDependencyResolver(injector.Container);
        DependencyResolver.SetResolver(autofacDependencyResolver);

        GlobalConfiguration.Configuration.DependencyResolver = new AutofacWebApiDependencyResolver(injector.Container); //For WebAPI dependency injection

        AreaRegistration.RegisterAllAreas();

        AutoMapperConfig.RegisterMappings(Mapper.Configuration);

        //Reference: http://www.asp.net/mvc/tutorials/mvc-5/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2
        GlobalConfiguration.Configure(WebApiConfig.Register);

        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);

        GlobalConfiguration.Configuration.EnsureInitialized();

#if DEBUG
        // Uncomment this line for the nhibernate profiler 
        // and add HibernatingRhinos.Profiler.Appender.dll
        // to the PD.UserInterfacePbj project references

       //HibernatingRhinos.Profiler.Appender.NHibernate.NHibernateProfiler.Initialize();

    }

I was able to resolve the issue by adding the following to the appSettings section as per the response to this question.

<add key="autoFormsAuthentication" value="false" />
<add key="enableSimpleMembership" value="false"/>
