消息NETSDK1057:您正在使用. NET的预览版本。请参阅:https://aka.ms/dotnet-support-policy

如何告诉Visual Studio使用. NET Core 5编译此项目？

. NET 5安装在我的机器上：

PS B:\...> dotnet --list-sdks
5.0.413 [C:\Program Files\dotnet\sdk]
7.0.100-rc.2.22477.23 [C:\Program Files\dotnet\sdk]

_{是的，我知道.NET Core 5已经过时了。}

确切的版本是Visual Studio 2022 17.4.0预览版6

设置＜code＞全局。json＜/code＞文件和解决方案文件一起指定要使用的SDK版本。

{
  "sdk": {
    "version": "5.0.413",
    "rollForward": "latestFeature"
  }
}
