Get current user id in ASP.NET Identity 2.0
asp.net, asp.net-identity, c#
Solution
`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;`.
Problem
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?
