Totally Blank Unity / Microsoft Store Build fails WACK tests

Question

I have been trying to get a successful build for my game in Unity 2018.2.1f1 and Visual Studio 2017 15.8.0.

After trying unsuccessfully to get a successful build / package / WACK for the windows store with all/every different configuration, I tried a totally blank default Unity, UWP platform app, generated a visual studio project. generated some icons, associated it with an app I had in the store. Built it, packaged it and run the WACK tests.

FAILED

Supported APIs

Error Found: The supported APIs test detected the following errors: API ExecuteAssembly in uwphost.dll is not supported for this application type. WinTest2.exe calls this API. API DllGetActivationFactory in uwphost.dll is not supported for this application type. WinTest2.exe has an export that forwards to this API. Impact if not fixed: Using an API that is not part of the Windows SDK for Microsoft Store apps violates the Microsoft Store certification requirements. How to fix: Review the error messages to identify the API that is not part of the Windows SDK for Microsoft 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:

What do I have to do to make a successful app build that I can actually get into the store. (What configuration, what unity / visual studio versions.) I have tried later versions of unity 2018.2.1 and 2018.2.2 (i think) and could not get a successful build out of them.

A while ago, i could not get a successful build out of Unity, so I reinstalled Win 10 Pro, Unity and Visual Studio. Still problems persist.

I have the same problem on VS2017 Community **15.9.4** – Jan 01 '19 at 07:54 — , Jan 01 '19 at 07:54

Thanks to StormBringerStudios I received an answer that works.

"Just Got Visual Studio 2017 15.7.6 version. works like a charm.

So here is my Solution is anyone will search this kind of problem DONT USE VS 2017 15.8.X.

Downgrade to 15.7.6 and you will be good :)

Microsoft certification also passed."

Wow, seriously? – Adrian K Feb 05 '19 at 18:49
Yes, seriously. – Haydn Feb 05 '19 at 23:04
I submitted my WACK failing app to the MS Store - it seems to have passed validation (on upload), we'll see how the rest of the submission goes. – Adrian K Feb 06 '19 at 05:07
Yeah, Should be interesting, Let me know which version you are using, if it passes. – Haydn Feb 06 '19 at 06:39
