MSB3073:命令dotnet bundle clean在Visual Studio 2019 Asp.NetCore

Question

我在Visual Studio 2019 Asp.NetCore项目中MSB3073: The command dotnet bundle clean exited with code 1收到错误。此问题仅在我昨天更新了Visual Studio之后才发生。

Visual Studio 版本是 16.1.0。

我不知道为什么dotnet使用回退文件夹。我也不知道为什么该文件夹不存在，因为我已在Visual Studio 2019中安装了Xamarin支持。

这个问题可以很容易地解决：只需将文件夹C:ProgramDataXamarinNuGet添加为空文件夹即可避免此问题。
