SignInManager WindowsUser NULL in Release Builds - No WindowsUser

[NoelStephensNILC]

Using Unity 2019.4.6f1, if you build either debug or release from within Unity editor for UWP and then build a RELEASE x64 version using the resulting solution from the editor's build then upon invoking the SignInPlayer Coroutine on Windows 10 the following call: Windows.System.User.FindAllAsync().AsTask();

Will always return a userTask status of "TaskStatus.RanToCompletion" but will return 0 (zero) results. This is problematic for the GameSaveHelper as it requires the WindowsUser in order to successfully call GameSaveProvider.GetForUserAsync during the GameSaveHelper's Initialize Coroutine.

If you run the same build generated from the editor in Debug mode, then it always returns a valid WindowsUser.

Any advice on how to get this functionality working in release?

I think this is probably related to: https://forum.unity.com/threads/solved-uwp-xbox-live-creators-cloud-save-connected-storage-issue.655441/.

Using the information provided for that issue I modified the SignInPlayer couroutine (in SigninManager.cs) slightly to read as follows - hope this helps. Cheers, S.

    /// <summary>
    /// Adds and signs in a new Xbox Live User and assigns it a player number.
    /// Note: Different platforms support a different number of users. 
    /// AddUser might fail if the player number is not within the range of supported users.
    /// </summary>
    /// <param name="playerNumber">The Player Number that should be assigned to the Xbox Live User</param>
    public IEnumerator SignInPlayer(int playerNumber)
    {
        yield return null;

        if (!CurrentPlayers.ContainsKey(playerNumber))
        {
            XboxLivePlayerInfo newPlayerInfo = new XboxLivePlayerInfo()
            {
                SignInCallbacks = new List<UnityAction<XboxLiveUser, XboxLiveAuthStatus, string>>(),
                SignOutCallbacks = new List<UnityAction<XboxLiveUser, XboxLiveAuthStatus, string>>()
            };
            CurrentPlayers.Add(playerNumber, newPlayerInfo);
        }

Hey everyone, Just for awareness in case this is still an issue, we've posted an announcement that integrating Xbox Live is no longer a requirement for UWP games to be published on Xbox as part of the Creators Program.
