Answer 1

For the controller, have a dependency on UserManager<ApplicationUser>. Then, you can access the ApplicationUser through the HttpContext of the request. I wrote an extension method for my project:

 public static class IdentityExt
 {
    public static Task<T> GetCurrentUser<T>(this UserManager<T> manager, HttpContext httpContext) where T: class{
        return manager.GetUserAsync(httpContext.User);
    }
 }

That returns the current user, and will allow you to access all of their properties.

Here it is inside an action:

public Task<IActionResult> Index(){
     var user = await _userManager.GetCurrentUser(HttpContext);
}
