In Windows App SDK 1.4, the min/max/close caption buttons for ExtendsContentIntoTitleBar = true are now drawn by AppWindow rather than XAML.
TitlebarHelper needs to be updated, because now the titlebar color is set like this:

App.MainWindow.AppWindow.TitleBar.BackgroundColor = ...
App.MainWindow.AppWindow.TitleBar.ButtonHoverBackgroundColor = ...

Well, I've got the beginnings of a fix for that, I'll keep looking at it over the next few days to push the changes ^^.

Hi, thanks for the patience. For some time, I have been on-and-off investigating and working on this crash issue. #4707

this is the reason, I am not been able to test this out this change because it could have ripple effects. Also my machine state is entirely broken because of that. Given it is a iterative change, I think it can wait. We anyways need the crash to be fixed before next version of Template Studio can get released

Well, now that #4707 is closed, I think we can get on with updating TemplateStudio for WASDK 1.4 ^^.

Thanks for the patience. I have reviewed this PR. Only minor changes are needed else it looks good. Once done, it can be merged and I will trigger newer version of template studio binary
