UWP Cant Submit to store Error API FreeAddrInfoEx

[liliyashka]

I have installed the new update from nuget 6.2.2 and I get a certification error when the app is processing. Here is the result.
Supported APIs
Error Found: The supported APIs test detected the following errors:
API FreeAddrInfoEx in ws2_32.dll is not supported for this application type. myApp.dll calls 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:

Same problem for our app. Downgrading to v6.1.9 fixes this.

Thanks for bringing this to our attention and sorry for the trouble. This seems to be caused by a reference to this API being added in dotnet/corefx#26850. This was subsequently fixed to rely on the supported API in dotnet/corefx#29919 but that change didn't make it to the version of the framework UWP 6.2.2 shipped with. We'll look into addressing this problem.

How long will it take to fix? Thanks.

Is there any workaround to fix this issue, like updating specific .NET NuGet dependency? Or should we use Microsoft.NETCore.UniversalWindowsPlatform 6.1.9 before this issue is fixed?
It's also strange that the Windows App Certification Kit 10.0.17763.132 does not show any problem with unsupported API when testing the app locally.

Have the same issue!

[Levvy055]

Also the same. And getting it on local cert tool

[shaishavbhatt08]

Use Microsoft.NETCore.UniversalWindowsPlatform 6.1.9, Next release will solve the issue i hope.

[shaishavbhatt08]

I submitted the app with use Microsoft.NETCore.UniversalWindowsPlatform 6.1.9 and it did not fail

I also had to downgrade... how is the nuget 6.2.2 not fixed or removed yet? This is causing devs to waste hours

[MichalStrehovsky]

how is the nuget 6.2.2 not fixed or removed yet?

It was pulled down a couple days ago: 6.1.9 is the latest stable package: https://www.nuget.org/packages/Microsoft.NETCore.UniversalWindowsPlatform

We are working on an update with a fix for this issue.

[LanceMcCarthy]

Any update on the progress of this?

[yrest]

Automatically updated to 6.2.2 today unaware of the issue, this is ridiculous.

[MichalStrehovsky]

@yrest The 6.2.2 package is still unpublished: https://www.nuget.org/packages/Microsoft.NETCore.UniversalWindowsPlatform. You shouldn't be offered to update to 6.2.2.

[LanceMcCarthy]

It looks like 6.2.3 is now officially available. @yrest @erossetto @shaishavbhatt08
