那些遇到过的问题

“全局使用指令”功能当前处于预览状态并且*不受支持*。要使用预览功能，请使用“预览”语言版本

Ven*_*kat 2 azure-devops

当我在 azure-dev-ops 中运行管道时，出现这样的错误。我在我的开发机器中使用 Visual Studio 2022 并针对 .net Framework 6.0

这是 vs-build 的 YAML 文件的一部分，我选择了 17.0，我假设它指向 vs-2022。

steps:
- task: VSBuild@1
  displayName: 'Build solution **\*.sln'
  inputs:
    solution: '$(Parameters.solution)'
    vsVersion: 17.0
    msbuildArgs: '/p:DeployOnBuild=true /p:DeployDefaultTarget=WebPublish /p:WebPublishMethod=FileSystem /p:publishUrl="$(Agent.TempDirectory)\WebAppContent\\"'
    platform: '$(BuildPlatform)'
    configuration: '$(BuildConfiguration)'
Run Code Online (Sandbox Code Playgroud)

错误和警告如下。然而，这在我的 Visual Studio 2022 中运行是一流的，并且也发布到 azure。然而，问题出在 azure devops 的管道中。

错误是：

[错误]BlazorAppDB\Shared\obj\Release\net6.0\BlazorAppDB.Shared.GlobalUsings.g.cs(8,1)：错误 CS8652：功能“全局使用指令”当前处于预览状态且不受支持。要使用预览功能，请使用“预览”语言版本。

警告是：

##[警告]C:\Program Files\dotnet\sdk\6.0.203\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.DefaultItems.targets(134,5)：警告 NETSDK1182：针对 .NET不支持 Visual Studio 2019 中的 6.0。

您似乎正在使用 Windows 2019 代理。如果启用 system.debug 变量（将值设置为 \xe2\x80\x9ctrue\xe2\x80\x9d），则在 VSBuild 任务中##[warning]Visual Studio version \'17.0\' not found. Falling back to version \'16.0\'选择时将看到此警告。vsVersion: 17.0

\n

请尝试使用windows 2022代理（windows-latest）看看是否有效。您可以在此处查看Windows 2022的软件列表。
