What a strange issue. I've seen some lag when loading the ListView, which I'm guessing is related to the data being populated.

CC: @MikeHillberg @marb2000 @anawishnoff - should I move this to the WinUI repo?

I'm tired.

Sorry, just seeing this now. @stmoy / @sdegutis I'm not able to repro this after cloning the latest Preview 3 version of XCG. I think this is probably just lag loading the data as Steven mentioned, so not sure if this requires an issue on the WinUI repo, i.e. I don't know if this is a new issue.

Was this ever fixed? To me this looks like Assets\Contacts.txt is checked in with wrong line endings, so

public async static Task<ObservableCollection<Contact>> GetContactsAsync()
{
    IList<string> lines = await FileLoader.LoadLines("Assets/Contacts.txt");

    ObservableCollection<Contact> contacts = new ObservableCollection<Contact>();

    for (int i = 0; i < lines.Count-2; i += 3)
    {
        contacts.Add(new Contact(lines[i], lines[i + 1], lines[i + 2]));
    }

    return contacts;
}

loads only one line and the for loop does nothing...

EDIT: A big LOL to whom, who thinks an application that runs solely on windows and is developed on windows to use UNIX line endings in the whole project is a good idea.
