"The type IUserStore`1 does not have an accessible constructor " Error when implementing default Identity Role in ASP.NET MVC Application

System.InvalidOperationException: The type IUserStore`1 does not have an accessible constructor. 

The AccountController class has two constructors, a default one with no parameter and another expecting a UserManager<T> object.when the class gets instantiated, Unity takes by default the one with the most parameters.

Hence,In the location where the types are registered in the Unity container (var container = new UnityContainer()) for global.asax,cs ,the following line has to be added :-

container.RegisterType<AccountController>(new InjectionConstructor());
