Does someone know if Azure DevOps pipelines have support for building .NET 5.0 code ?
回答1:
Yes, Azure DevOps Pipelines can build net5.0 apps.
If you are building with ".Net Core" (DotNetCoreCLI in yaml) task - add "Use .NET Core" (UseDotNet in yaml) task before it, with correct version:
- task: UseDotNet@2
inputs:
packageType: 'sdk'
version: '5.0.x'
- task: DotNetCoreCLI@2
displayName: 'dotnet build'
inputs:
command: 'build'
回答2:
It's supported.
Since you are using .Net 5, instead of using Nuget restore, try to use Use .net core taskand Dotnet core task with restore command.
- 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'
It's strongly recommended to use dotnet restore and dotnet build tasks for projects that target .net core. See this statement from Nuget task:
