Summary0027734: Build UWP: Users reporting submission fails for unallowed functionality when submitting their games to the store
DescriptionHello, I am getting a failed certification when I submit my game to the windows store. Here is the report:

Supported API test

Supported APIs

Error Found: The supported APIs test detected the following errors:
API getenv in api-ms-win-crt-environment-l1-1-0.dll is not supported for this application type. WinUAPRunner.exe calls this API.

Impact if not fixed: Using an API that is not part of the Windows SDK for Windows Store apps violates the Windows Store certification requirements.

How to fix: Review the error messages to identify the API that is not part of the Windows SDK for Windows Store apps. Please note, apps that are built in a debug configuration or without .NET Native enabled (where applicable) can fail this test as these environments may pull in unsupported APIs. Retest your app in a release configuration, and with .NET Native enabled if applicable.

Runtime released a short while ago today to fix this. Have submitted a valid package to the store page for QuadBreak using this version.
