有人知道Azure DevOps管道是否支持构建。NET5.0代码？

Answer 1

我需要使用这两个框架版本来构建我的函数。净5

步骤：

- task: UseDotNet@2
  inputs:
    version: '5.0.x'
    packageType: sdk
    includePreviewVersions: false

- task: UseDotNet@2
  inputs:
    version: '3.1.x'
    packageType: sdk
    includePreviewVersions: false

Answer 2

它得到了支持。

因为您正在使用。Net 5，而不是使用Nuget restore，尝试使用use。net核心任务和带有restore命令的Dotnet核心任务。

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

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

强烈建议对目标为的项目使用dotnet restore和dotnet build任务。net核心。请参阅Nuget任务中的以下语句：

这里还要看一看类似的问题：Blazor的Azure CI管道。NET5不起作用

Answer 3

是的，Azure DevOps管道可以构建net5。0应用程序。

如果你正在建设与"。Net Core"（DotNetCoreCLIin yaml）任务-add"使用。NET Core"（UseDotNetin yaml）之前的任务，具有正确的版本：

- task: UseDotNet@2
  inputs:
    packageType: 'sdk'
    version: '5.0.x'

- task: DotNetCoreCLI@2
  displayName: 'dotnet build'
  inputs:
    command: 'build'
