User.Identity.GetUserId() returns null

[nkirkes]

Could be I'm doing something wrong in my configuration, but when I try to use this extension method, I get a null value returned. After peeking the definition of the method, it's trying to get the user id via the Claims collection for the user, for which there aren't any. The user has an _id value, but Claims is empty. Specifically, the method tries to find the NameIdentifier claim(which I thought was odd usage for that).

Have you seen this before? Any thoughts on what I could be doing wrong? Happy to elaborate if needed.

I have the same problem, but if you want to get the id user you can use UserManager.FindByEmail(model.Email) that returns a kind of user object with roles and more data like the id.

It's not a good solution but it works :(
