Get current user id in ASP NET Identity 2 0

Question

I just switched over to using the new 2 0 version of the Identity Framework   In 1 0 I could get a user object by using manager FindByIdAsync User Identity GetUserId      The GetUserId   method does not seem to exists in 2 0   Now all I can figure out is to use manager FindByEmailAsync User Identity Name  which references the username field in the users table   In my application this is set to the same as the email field     I can see this causing issues down the road when someone needs to update their email  Is there a way to get the current logged in user object based off an unchanging value  such as the id field  in the Identity 2 0 Framework

Just in case you are like me and the Id Field of the User Entity is an Int or something else other than a string    using Microsoft AspNet Identity   int userId   User Identity GetUserId lt int gt       will do the trick

GetUserId   is an extension method on IIdentity and it is in Microsoft AspNet Identity IdentityExtensions  Make sure you have added the namespace with using Microsoft AspNet Identity
