Blazor .NET 5的Azure CI管道不起作用

如何解决Blazor .NET 5的Azure CI管道不起作用

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

我将应用程序升级为使用.NET 5 RC，并且管道不再起作用。

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'

有效。

但是构建任务失败并显示：

...
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，如果执行此操作，则在构建版本之前，还原任务将失败。这样看来，SDK在某种程度上是“可访问的” ...
还有其他想法吗？
预先感谢。

解决方法

将UseDotNet任务更改为以下内容，以确保将Visual Studio 2019预览与.NET5预览结合使用：

- 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 门户 > 应用服务 > 您的 api > 配置 > 常规设置并将堆栈切换到 NET 并将 NET 框架版本切换到 NET 5。

我在azure帐户上设置了一个简单的应用程序服务，然后尝试将其部署到该服务。我可以在Visual Studio中使用“发布”功能来完成此操作，但是我无法在管道中执行相同的操作。从构建解决方案开始，发布就可以完成所有工作。我知道我在管道上有zip文件，但是例如当我尝试

- task: AzureWebApp@1
  inputs:
    azureSubscription: '<details>'
    appType: 'webApp'
    appName: '<name>'
    package: '$(System.DefaultWorkingDirectory)/**/*.zip'
    deploymentMethod: 'auto'

我收到此错误：

Got service connection details for Azure App Service:'DevOpsBlazorticketsWebApp'
Trying to update App Service Application settings. Data: {"WEBSITE_RUN_FROM_PACKAGE":"1"}
Deleting App Service Application settings. Data: ["WEBSITE_RUN_FROM_ZIP"]

我尝试了所有其他可能性，但是我找不到办法...
