New build pipeline

Create new build pipeline that generates packages

For places where we can't use Provisionator, I've been doing the following to ensure the right macos workload version gets installed. The workloads property in global.json is made up but I think it's convenient.

Pipeline:

- task: UseDotNet@2
  displayName: 'Use .NET SDK'
  inputs:
    useGlobalJson: true
    includePreviewVersions: true

- task: PowerShell@2
  displayName: 'Provision .NET workloads'
  inputs:
    filePath: $(Build.SourcesDirectory)\build\Install-DotNetWorkload.ps1
    arguments: '-globalJsonPath $(Build.SourcesDirectory)\global.json'
    pwsh: true

global.json:

{
  "sdk": {
    "version": "6.0.200"
  },
  "workloads": {
    "microsoft.net.sdk.macos": {
      "version": "12.1.301-preview.13.4",
      "sources": [
        "https://aka.ms/dotnet6/nuget/index.json",
        "https://api.nuget.org/v3/index.json"
      ]
    }
  }
}

Install-DotNetWorkload.ps1:

param(
    [string]$globalJsonPath,
    [string]$dotnetPath = "dotnet"
)

$GlobalJson = Get-Content $globalJsonPath | ConvertFrom-Json

foreach ($workload in $GlobalJson.workloads.PSObject.Properties) {
    $workloadName = $workload.Name
    $shortWorkloadName = $workloadName.Substring($workloadName.LastIndexOf(".") + 1)
    $workloadVersion = $workload.Value.version

    Write-Host "Preparing to install workload $workloadName ($shortWorkloadName) $workloadVersion..."

    Write-Host "  Uninstalling $shortWorkloadName..."

    # TODO: This requires elevated access, at least on Mac.
    & $dotnetPath workload uninstall $shortWorkloadName

    $rollbackJson = @{}
    $rollbackJson[$workloadName] = $workloadVersion

    $rollbackFile = New-TemporaryFile
    $rollbackJson | ConvertTo-Json | Set-Content -Path $rollbackFile

    $sourcesArgs = @()
    foreach ($source in $workload.Value.sources) {
        $sourcesArgs += "--source"
        $sourcesArgs += $source
    }

    Write-Host "  Installing $shortWorkloadName..."

    # TODO: This requires elevated access, at least on Mac.
    & $dotnetPath workload install $shortWorkloadName --from-rollback-file $rollbackFile $sourcesArgs

    Remove-Item $rollbackFile
}
