Can anybody help me to find out how authorize attribute is fetching roles from identity user table.I mean to say where is IsUserInRole method defined or Where is GetUserForRoles defined or everything happens internally.
I am not new to MVC and can create custom RoleProvider or can write code on OnAutherize method for creating principle ,but i want to know how the default Account Controller works and even when i am not specifying any logic to fetch role ,how roles are being fetched from database??
