I am currently trying to build and publish my app to the universal windows platform halfway through the process of doing so, during the validation process I got stopped with these errors. The 1st one I am clueless to what I can even do and the second one I don't know why is happening. Please help.

First error:

Supported API test FAILED

Supported APIs

  • Error Found: The supported APIs test detected the following errors:

    • API D3D12GetDebugInterface in d3d12.dll is not supported for this application type. UnityPlayer.dll 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. See the link below for more information: Alternatives to Windows APIs in Windows Store apps.

Second error:

App resources FAILED

Branding

  • Error Found: The branding validation test encountered the following errors:
    • Image file SplashScreen.scale-200.png is a default image.
  • Impact if not fixed: Windows Store apps are expected to be complete and fully functional. Apps using the default images e.g. from templates or SDK samples present a poor user experience and cannot be easily identified in the store catalog.
  • How to fix: Replace default images with something more distinct and representative of your app.

Here is the full output for further details:

  • \$\begingroup\$ So far I have fixed the first problem by setting the build type to Master. \$\endgroup\$ – Jayson Meribe Mar 24 '18 at 17:21
  • \$\begingroup\$ I fixed the second problem by going into the project assets and changing the splash screen image 200 to an image that was 1240 x 600 and naming it the same thing \$\endgroup\$ – Jayson Meribe Mar 26 '18 at 11:07
