asp.net - Azure DevOps Pipelines 可以构建 ASP.NET 网站吗？

Question

我有一个使用 ASP.NET 网站(不是 ASP.NET Web 应用程序)的旧代码库，并且正在尝试在 Azure 上为其构建管道开发运营。

在进程到达 aspnet_compiler.exe 时遇到一些困难后，我创建了一个简单的测试解决方案，其中包含从 VS2019 中的模板生成的单个 ASP.NET Web 表单站点。然后，我使用 ASP.NET 模板创建了一个 Pipeline 并运行它，最终以熟悉的失败告终。测试解决方案和实际解决方案在同一位置失败，所以至少我已经查明了问题......不幸的是，我不知道如何解决它。

构建步骤的完整日志位于我的帖子底部，但这是我特别陷入困境的地方:

Project "D:\a\9\s\Hello.sln" (1) is building "D:\a\9\s\WebSite1_1_.metaproj" (2) on node 1 (default targets).
Build:
  C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_compiler.exe -v /localhost_51752 -p WebSite1\ -u -f PrecompiledWeb\localhost_51752\ 
##[error]WebSite1\web.config(116,0): Error ASPCONFIG: The CodeDom provider type "Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=2.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" could not be located.
D:\a\9\s\WebSite1\web.config(116): error ASPCONFIG: The CodeDom provider type "Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=2.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" could not be located. [D:\a\9\s\WebSite1_1_.metaproj]

我应该注意到，这似乎与 Microsoft.CodeDom.Providers.DotNetCompilerPlatform 程序集无关。在我实际的 ASP.NET 网站(不是我正在使用的这个小测试网站)中，如果网站的web.config 包含此内容，例如:

    <compilation debug="true" defaultLanguage="c#" targetFramework="4.8">
      <assemblies>
        <add assembly="Microsoft.Web.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
      </assemblies>
    </compilation>

在这种情况下，它将抛出相同的错误，但有关 Microsoft.Web.Infrastruct 的错误。显然，aspnet_compiler.exe 无法找到我的引用，但我不知道缺少什么 - 引用是否没有被复制到某个地方，或者进程是否没有在正确的位置寻找它们，或者...？

以下是整个 Azure DevOps Pipeline 构建日志:

网站似乎需要一点额外的爱才能在 Azure DevOps Pipeline 中工作，但它们可以工作。这是我着陆的地方...

1. 管道环境未安装 Visual Studio。确保您的 *.refresh 文件指向下载的包(即 NuGet 自动放入您的包目录中的内容)，而不是 Visual Studio 共享包目录。

例如，在新的网站项目中，Bin\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.dll.refresh 的内容默认为:

..\..\..\Program Files (x86)\Microsoft Visual Studio\Shared\Packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.2.0.1\lib\net45\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.dll

...但应该是:

..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.2.0.1\lib\net45\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.dll

NuGet 不知道它需要恢复网站的包，因为没有 *.csproj 告诉它这一点。添加自定义 NuGet 恢复任务(其中“WebSite1”是您的网站所在的目录):

steps:
- task: NuGetCommand@2
  displayName: 'NuGet Restore for Web Site'
  inputs:
    command: custom
    arguments: 'restore $(Build.SourcesDirectory)\WebSite1\packages.config -SolutionDirectory $(Build.SourcesDirectory)'

在运行 aspnet_compiler.exe 之前，NuGet 不会运行安装 PowerShell 脚本将所有 Roslyn 文件放入 Bin 目录中。您必须通过复制文件任务自行完成此操作:

steps:
- task: CopyFiles@2
  displayName: 'Copy Roslyn files'
  inputs:
    SourceFolder: '$(Build.SourcesDirectory)\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.2.0.1\tools\RoslynLatest'
    TargetFolder: '$(Build.SourcesDirectory)\WebSite1\Bin\roslyn'
