What is Authorization in ASP.NET Core? See Example

Authorization in ASP.NET Core is the process of controlling access to resources based on user identity, roles, or policies. It works after authentication and ensures that users can only access permitted areas of an application.

Key Features:

• Supports role-based and policy-based authorization
• Integrates with ASP.NET Core Identity
• Works with MVC, Razor Pages, and APIs
• Flexible and customizable access control
• Enhances security of web applications

Example:
Role-based authorization in a controller:

[Authorize(Roles = "Admin")]
public class AdminController : Controller
{
    public IActionResult Dashboard()
    {
        return View();
    }
}

Policy-based authorization example:

services.AddAuthorization(options =>
{
    options.AddPolicy("MustBeManager", policy =>
        policy.RequireRole("Manager"));
});

Authorization in ASP.NET Core ensures that only authorized users can perform specific actions, keeping your applications secure and well-managed.
