如何获取UWP App中当前登录用户的用户名或ID

Question

I found this article: Get The Username/User Id Of Currently Logged In User In A UWP App

to get the username of current user logged in in uwp app , but when I tried the accepted answer , it returns null/empty , is there any updated version of that?

NOTE: Iam using a microsoft account

UPDATE: All properties from "KnownUserProperties" returns empty string except for "First Name" & "Last Name"

Thanks

Answer 1

private async void Page_Loaded(object sender, RoutedEventArgs e)
{
    IReadOnlyList<User> users = await User.FindAllAsync();

    var current = users.Where(p => p.AuthenticationStatus == UserAuthenticationStatus.LocallyAuthenticated && 
                                p.Type == UserType.LocalUser).FirstOrDefault();

    // user may have username
    var data = await current.GetPropertyAsync(KnownUserProperties.AccountName);
    string displayName = (string)data;

    text1.Text = displayName;
}

Did enable the User Account Information in the package.appxmanifest ?

Here is the image which shows the manifest file.
