Got the following ProviderException :
The Role Manager feature has not been enabled.
So far so good.

If you are using ASP.NET Identity UserManager
you can get it like this as well:
var userManager = Request.GetOwinContext().GetUserManager();
var roles = userManager.GetRoles(User.Identity.GetUserId());
If you have changed key for user from Guid to Int for example use this code:
var roles = userManager.GetRoles(User.Identity.GetUserId());
