Build errors (MSB4018) with VS2019 version 16.10

Hi,

We have an Azure Functions project using PlayFabSDK, which was working fine in VisualStudio 16.9.6. Recently a few of us updated VS to 16.10.0 and started getting the following build error:

1>Build FAILED.

After turning on some more verbose build logging, it looks like the error is due to the TargetFrameworks tag in PlayFabSDK.csproj

<TargetFrameworks>netstandard2.0;netstandard1.1;net45;portable45-net45+win8+wpa81</TargetFrameworks>

Removing "portable45-net45+win8+wpa81" from that list fixed our build errors, and didn't seem to cause any other problems.

  • Is this a wider/known issue, or something unique to our project setup/configuration?
  • Is there a more correct fix?
  • Will PlayFab address it in a future release?

Thanks,

Dan Nottingham

Thanks for the sharing. After testing, we found that the PlayFab SDK NuGet package won't cause this issue, you can try to import the PlayFab SDK NuGet Package to your project.
