关于 yaml：Azure Pipeline for .NET Core 3.0 P9 不起作用

Azure Pipeline for .NET Core 3.0 P9 does not work

我有一个使用 3.0 P9 的简单 Blazor 项目，该项目在我的本地机器上构建良好，将其签入 azure devops，创建了一个获取

的管道

C:\\hostedtoolcache\\windows\\dotnet\\sdk\\3.0.100-preview9-014004\\Sdks\\Microsoft.NET.Sdk\\targets\\Microsoft.PackageDependencyResolution.targets(234,5):
Error NETSDK1004: Assets file
'd:\\a\\1\\s\\projectname\\obj\\project.assets.json' not found. Run a
NuGet package restore to generate this file. Process 'msbuild.exe'
exited with code '1'.

使用以下 yaml 运行管道时(任务 UseDotNet@2 和 DotNetCoreInstaller@0 已添加到默认生成的管道代码中)

Azure Pipeline for .NET Core 3.0 P9 does not work

要解决此问题，请在任务 Visual Studio build 之前添加一个 dotnet restore 任务：

11

- task: DotNetCoreCLI@2

displayName: 'dotnet restore'

inputs:

command: restore

projects: '**/YourProjectName.csproj'

vstsFeed: 'XXXX'

发生错误是因为 dotnet cli 最初没有创建所有必需的文件。执行 dotnet restore 会添加所需的文件。

希望这会有所帮助。
