Comment
API of the file api-ms-win-core-debug-l1-1-1.dll has been moved to the following DLL:
APIs from api-ms-win-core-debug-l1-1-1.dll
Cause
If your application is missing the file api-ms-win-core-debug-l1-1-1.dll it's most likely because developpers create a link to it directly instead of linking your app with WindowsApp.lib to access these APIs.
Developpers must never link APIs directly to api-ms-win.* files, they have to use WindowsApp.lib instead.*
All errors related to a missing api-ms-win.*.dll should be considered as a BUG, as developpers have to change the link of the API to point to WindowsApp.lib instead of the API dll to use that API.
