How can 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 userManager.AddToRoleAsync(user, roleName);

This adds the specified role to the user.

What if the role doesn't exist yet?

You can create a role using the RoleManager like this:

await roleManager.CreateAsync(new IdentityRole(roleName));

Make sure to check if the role already exists before creating it.
