What is ASP.NET Core Identity and how does it handle authorization?

ASP.NET Core Identity is a membership system that adds login functionality to your application. It handles user authentication and authorization, allowing you to manage user roles and claims.

Can you explain how roles work in ASP.NET Core Identity?

Roles in ASP.NET Core Identity allow you to group users and assign permissions. You can create roles like 'Admin' or 'User' and then assign users to these roles to control access to different parts of your application.

How do I implement role-based authorization in my app?

To implement role-based authorization, you can use the [Authorize(Roles = "RoleName")] attribute on your controllers or actions. This restricts access to users who belong to the specified role.

What are claims and how do they differ from roles?

Claims are key-value pairs associated with a user that provide additional information, like email or permissions. Unlike roles, which are broader categories, claims can be more granular and specific.
