问题 Is it possible to program a startup hold into an Xbox game package that waits for the user's cloud saves to sync before continuing? I have an HTML5 game package for which I require save data to be loaded from Xbox Live which is then read from local storage (in JSON format) to populate the load screen at startup, and I also have to account for any error messages for which the user may have to respond.

问题 Related to this question, I am trying to implement a procedure that uses the WinRT API to set the desktop wallpaper. To mimic the await functionality in C#, I am using TTask.Future (link) as outlined here and here.

I have found on two test tablets that I can re-create the problem by going to task manager and creating a dump file for the running app. After I do this twice and
