問題
As of November 1st 2021, new applications and application updates uploaded to the Google Play store need to target v11.0 (API 30) or above.
解決方法
If you are seeing this warning, you should update the $(TargetFrameworkVersion) of your projects to be v11.0 or above.
如果您不是以Google Play商店為目標,而且想要隱藏這些警告,您可以使用 /warnasmessage:XA0113 命令行參數。 或者,新增
<PropertyGroup>
<MSBuildWarningsAsMessages>XA0113</MSBuildWarningsAsMessages>
</PropertyGroup>
to your .csproj file.
