How do I manage user roles in ASP.NET Core Identity?

You can manage user roles in ASP.NET Core Identity by using the RoleManager and UserManager classes. Would you like a code example?

Yes, please provide a code example for adding a role to a user.

Sure! First, ensure you have the RoleManager injected. Then, you can use the following code:

var user = await userManager.FindByIdAsync(userId);
await roleManager.CreateAsync(new IdentityRole("Admin"));
await userManager.AddToRoleAsync(user, "Admin");

What if the role already exists?

If the role already exists, you can skip creating it and directly add the user to that role using:

await userManager.AddToRoleAsync(user, "Admin");
