ASP.NET MVC 5 how to delete a user and its related data in Identity 2.0

September 8, 2023 by Tarik

I think the classes you’re looking for are the UserManager and the RoleManager. In my opinion they are the better way instead of going against the context directly. The UserManager defines a method RemoveFromRoleAsync which gives you the ability to remove the user (identified by his key) from a given role. It also defines several … Read more

When unit testing, how do I mock a return null from async method?

August 27, 2023 by Tarik

You get a compiler error because you return a task that doesn’t match the type the async method returns. You should return Task<Member> instead of simply Task<object>: repository.Setup(r => r.GetMemberAsync(email)).Returns(Task.FromResult<Member>(null));
