ASP Identity 2.0.0 usermanager calling wrong method?

Question

I have implemented a custom UserStore for my ASP MVC project (with Identity 2.0.0, which I use for it allows the use of integer keys).

The Usermanager is not custom implemented, but the Microsoft.AspNet.Identity.Usermanager implementation.

When I call:

IdentityResult result = await UserManager.CreateAsync(User, model.Password);

In my accountcontroller, the

public Task UpdateAsync(TUser user)

method is called instead of

 public Task CreateAsync(TUser user)

How could this be? Is it a known bug? Could I work around this?

Answer 1

Apparently, the "update" method is called, after which a select statement checks if the record is present in the table. If not (the select returns null), the Usermanager will do a create for the new record.
