问题
I have a problem with a Windows 10 UWP Store App.
In the app are two pages (Page1 and Page2) with similar xaml controls, but one page (Page1) cause a lot of problems while testing the app by microsoft. If they try to start the app the initialization of Page1 throw an exception. When I remove one specific xaml control all is fine, but Page2 contains exactly the same controls and works perfectly. On my local machine I have no exceptions, no warnings, the windows certification kit say the app has no problems and I can't reproduce the exception.
When I remove the AppBarButtons from the CommandBar on Page1, the test Microsoft testing guy has no exception. The similar CommandBar on Page2 cause no exception on the computer of the test guy.
Xaml code of Page1 (which has the problem):
<Page

</CommandBar.SecondaryCommands>
</CommandBar>
