added code from teacher's notes, but got error with UserManager Class.

I added the code from teacher's notes that prevents registration of duplicate e-mails, but I got an error with UserManager Class:

Error CS0305 Using the generic type 'UserManager<TUser, TKey>' requires 2 type arguments Treehouse.FitnessFrog D:\dotnet-user-auth-with-aspnet-identity-fitness-frog\Treehouse.FitnessFrog\Controllers\AccountController.cs 41 Active

The provided code snippet is wrong. It should be using _userManager instead of UserManager.

var existingUser = await _userManager.FindByEmailAsync(viewModel.Email);
