Creating Roles in Asp.net Identity MVC 5

Question

There is very little documentation about using the new Asp.net Identity Security Framework.

I have pieced together what I could to try and create a new Role and add

Answer 1

In ASP.NET 5 rc1-final, I did following:

Created ApplicationRoleManager (in similar manner as there is ApplicationUser created by template)

public class ApplicationRoleManager : RoleManager
{
    public ApplicationRoleManager(
        IRoleStore store,
        IEnumerable> roleValidators,
        ILookupNormalizer keyNormalizer,
        IdentityErrorDescriber errors,
        ILogger> logger,
        IHttpContextAccessor contextAccessor)
        : base(store, roleValidators, keyNormalizer, errors, logger, contextAccessor)
    {
    }
}

To ConfigureServices in Startup.cs, I added it as RoleManager

services.
    .AddIdentity()
    .AddRoleManager();

For creating new Roles, call from Configure following:

public static class RoleHelper
{
    private static async Task EnsureRoleCreated(RoleManager roleManager, string roleName)
    {
        if (!await roleManager.RoleExistsAsync(roleName))
        {
            await roleManager.CreateAsync(new IdentityRole(roleName));
        }
    }
    public static async Task EnsureRolesCreated(this RoleManager roleManager)
    {
        // add all roles, that should be in database, here
        await EnsureRoleCreated(roleManager, "Developer");
    }
}

public async void Configure(..., RoleManager roleManager, ...)
{
     ...
     await roleManager.EnsureRolesCreated();
     ...
}

Now, the rules can be assigned to user

await _userManager.AddToRoleAsync(await _userManager.FindByIdAsync(User.GetUserId()), "Developer");

Or used in Authorize attribute

[Authorize(Roles = "Developer")]
public class DeveloperController : Controller
{
}
