Blazor .NET 5 的 Azure CI 管道不起作用

Question

我有一个用于 WebAssembly Blazor 应用程序的现有 Azure CI 管道，它适用于 .NET Core 3.1。

我升级了应用程序以使用 .NET 5 RC，但管道不再工作了。

根据建议，我删除了 NuGet 任务，并插入了两个新任务：

- task: UseDotNet@2
  displayName: 'Use .NET Core sdk 5.0.100-rc.1.20452.10'
  inputs:
    version: '5.0.100-rc.1.20452.10'
    includePreviewVersions: true

- task: DotNetCoreCLI@2
  displayName: 'dotnet restore'
  inputs:
    command: restore
    projects: '**/*.csproj'

工作。

但是构建任务失败了：

...
ValidateSolutionConfiguration:
  Building solution configuration "release|any cpu".
  It was not possible to find any installed .NET Core SDKs
  Did you mean to run .NET Core SDK commands? Install a .NET Core SDK from:
      https://aka.ms/dotnet-download
##[error]Test1\Server\Server.csproj(0,0): Error : Unable to locate the .NET Core SDK. Check that it is installed and that the version specified in global.json (if any) matches the installed version.
D:\a\1\s\Test1\Server\Server.csproj : error : Unable to locate the .NET Core SDK. Check that it is installed and that the version specified in global.json (if any) matches the installed version.
##[error]Test1\Server\Server.csproj(0,0): Error MSB4236: The SDK 'Microsoft.NET.Sdk.Web' specified could not be found.
Project "D:\a\1\s\FluidTickets.sln" (1) is building "D:\a\1\s\Test1\Server\Server.csproj" (2) on node 1 (default targets).
D:\a\1\s\Test1\Server\Server.csproj : error MSB4236: The SDK 'Microsoft.NET.Sdk.Web' specified could not be found.
Done Building Project "D:\a\1\s\Test1\Server\Server.csproj" (default targets) -- FAILED.
...

在 StackOverflow 的另一个答案中，我读到了有关添加新变量的信息：

MSBuildSDKsPath = C:\agent\_work\_tool\dotnet\sdk\5.0.100-rc.1.20452.10\Sdks

但是，如果我这样做，那么在构建之前，还原任务就会失败。所以看起来 SDK 在某种程度上是“可访问的”...
还有什么想法吗？
提前致谢。

将您的 UseDotNet 任务更改为以下内容，以确保 Visual Studio 2019 预览版与 .NET5 预览版结合使用：

- task: UseDotNet@2
  displayName: 'Use .NET 5 SDK (preview)'
  inputs:
    packageType: 'sdk'
    version: '5.0.100-rc.1.20452.10'
    vsVersion: '16.8.0'
    includePreviewVersions: true

完整的 YAML 管道供您参考（这适用于我的 Blazor WASM .Net 5 项目）：

pool:
  vmImage: 'ubuntu-latest'

steps:

- task: UseDotNet@2
  displayName: 'Use .NET 5 SDK (preview)'
  inputs:
    packageType: 'sdk'
    version: '5.0.100-rc.1.20452.10'
    vsVersion: '16.8.0'
    includePreviewVersions: true

- task: DotNetCoreCLI@2
  displayName: 'NuGet restore'
  inputs:
    command: 'restore'
    projects: 'MyProject/MyProject.csproj'
    verbosityRestore: 'Normal'

- task: DotNetCoreCLI@2
  displayName: 'Build'
  inputs:
    zipAfterPublish: true
    command: publish
    publishWebProjects: false
    projects: 'MyProject/MyProject.csproj'
    arguments: '-c $(Build.Configuration) -o $(Build.ArtifactStagingDirectory) --no-restore'

- task: PublishBuildArtifacts@1
  displayName: 'Publish'
  inputs:
    PathtoPublish: '$(Build.ArtifactStagingDirectory)'
    ArtifactName: 'drop'
    publishLocation: 'Container'

还值得注意的是，一旦您将 api 升级为使用 NET 5，您需要进入 Azure Portal > App Services > Your api > Configuration > General Settings & 将 Stack 切换到 NET 并将 NET 框架版本切换到 NET 5。
