German settings

Asset Catalog editor in Visual Studio 2015, specially AppIcons, is not working correctly on Windows with regional settings which is not set to English formatting. It's probably caused by decimal separator set to comma, not dot.

My Asset Catalog is loaded correctly with English settings.

With German settings, the iPad Pro icon is displayed as "Unknown" and "iPad - iOS 7.0 and later" is reset to False.

For some other regional settings, for example Czech, the AppIcons are not loaded at all. If I save the solution, the key XSAppIconAssets is removed from Info.plist.

I can't update to version
The latest available version is (in Beta

So, how can I get the solution to this problem?
Comment 7 Petr Kucera 2016-11-03 08:52:09 UTC
Until the fix is published, the solution is changing your Windows configuration and setting decimal separator as dot "." in Number Format. Or simply change all formatting to "English (United States)".

- Close Asset Catalog in VS
- Close Visual Studio
- Change the settings or just decimal separator
- Reboot if necessary (in Windows 10 not required)
- Open Visual Studio, load the project/solution
- Check the Asset Catalog, you may need to set the option "iPad - iOS 7.0 and later" back to True and load missing images.

In which version is this bug supposed to be fixed (and verified)?
I am using the latest versions of xamarin and I still get the warning:
A 83.5x83.5@2x app icon is required for iPad apps targeting iOS 9.0 and later

The proposed 'solution' is a horrible suggestion. 
Changing the number format in windows can have all kinds of effects in other applications.
And I have the dutch settings for a reason....

Kind regards, Saskia

Hello Saskia,

The fix is available in our beta channel releases; currently that would be XVS (cycle9/7bbc66a).
