Next, create a new class named 'IdentityDbContext' that inherits from 'IdentityDbContext<User>'. This class will hold our identity data schema.

Do not forget to apply DbSet properties for the 'Users' and 'Roles' tables.

Configuring the Startup class

In your 'Startup.cs' file, add 'services.AddIdentity<User, Role>()' under the other service configurations. Ensure to pass your 'IdentityDbContext' as an argument in the configuration methods.

Then add the authentication and authorization middleware beneath the use of Kestrel.

Register View Creation

To create views for the AccountController, right-click on the 'Controllers' folder, select 'Add View', then 'Register.cshtml'. Repeat this process for 'Login.cshtml' and 'Logout.cshtml'.

Also, create a '_Layout.cshtml' file in the 'Views' folder for the site-wide navigation bar.

Creating Login and Logout Features

Within your 'AccountController.cs', implement the 'Login' and 'Logout' actions as per the MVC pattern. Ensure to configure your site's application cookie options appropriately.

Use the guide below for setting up the views for each action:

For 'Register', use helper methods like '@Html.TextBoxFor', '@Html.ValidationSummary', etc.
For 'Login', use '@Html.TextBoxFor', '@Html.PasswordFor', and '@Html.ButtonFor'.

Finally, navigate to '/Account/Login' in your browser. You'll see a login interface, signifying a successful setup. Register a new user and log in to test the full cycle. Your ASP.NET Core Identity tutorial journey ends here. Happy coding!
