How can I implement role-based authentication in ASP.NET Core?

To implement role-based authentication in ASP.NET Core, you can use ASP.NET Core Identity. First, ensure you have the Identity package installed.

What are the steps to set up ASP.NET Core Identity?

1. Install the necessary NuGet packages. 2. Configure services in Startup.cs. 3. Create roles and assign them to users.

Can you show me an example of creating roles?

Sure! You can create roles using the RoleManager class. Here's a sample code snippet:

var roleManager = serviceProvider.GetRequiredService<RoleManager<IdentityRole>>();
if (!await roleManager.RoleExistsAsync("Admin")) {
    await roleManager.CreateAsync(new IdentityRole("Admin"));
}
