How to create a user and get the newly created ID with ASP.NET Identity

Question

I am new to the ASP.NET Identity framework and am trying to do some things that I used to do in the older FormsAuthentication framework.

What I want to do is allow an administrative user to create a new user using the existing Register view (or similar) from within the app. Once this is complete, I would like to relationally associate that user (possibly using the ID that is generated) to other areas of the system.

How do I get access to the ID that is generated when calling UserManager.CreateAsync()?

EDIT: I am wanting existing users with "administrative" roles to create users from within the system in a User Management area. The answers below so far have explained how to get the ID for the "current" user which is not what I am looking for.

Answer 1

Using the IdentityUser or using a class that inherits from IdentityUser, makes the model having an UserId attribute. Using following code, passing the user to the method, will fill up the Id.

var user = model.GetUser(); var result = await UserManager.CreateAsync(user, model.Password);  if (result.Succeeded)     result = UserManager.AddToRole(user.Id, "User"); 

The model.GetUser() returns an object of the ApplicationUser or IdentityUser

public ApplicationUser GetUser() {     var user = new ApplicationUser     {         UserName = UserName,         FirstName = FirstName,         LastName = LastName,         Email = Email,         ...     };      return user; }
