Instead of the usual loosely typed:

@Html.ActionLink("Log in", "UserController", "LogIn")

You can now make action links strongly typed:

@Html.ActionLink("Log in", @typeof(UserController), @nameof(UserController.LogIn))

Now if you want to refactor your code and rename the UserController.LogIn method to UserController.SignIn, you don’t need to worry about searching for all string occurrences. The compiler will do the job.
