build.ps1 not installing .net core 3.0.100

See original GitHub issue

Description

The build script does not install the .net core version.

Steps to reproduce

Add a global.json with sdk 3.0.100

{
  "sdk": {
    "version": "3.0.100"
  }
}

Run the build script on a machine that does not have .net core 3.0.100

[CmdletBinding()]
Param(
    [Parameter(Position=0,Mandatory=$false,ValueFromRemainingArguments=$true)]
    [string[]]$BuildArguments
)

Write-Output "PowerShell $($PSVersionTable.PSEdition) version $($PSVersionTable.PSVersion)"

What I have tried

Changing these lines sometimes fixes the issue,

  New-Item -ItemType Directory -Path $TempDirectory | Out-Null
    
    #New-Item -ItemType Directory -Path $TempDirectory -ErrorAction SilentlyContinue | Out-Null

Other Issues

I get other issues as well. Even though I install .net core 3.0.100, this target will fail, saying that it could not find 3.0.100.

 Target CompileDroid => _ => _
        .Produces(OutputDirectory / "*.apk", OutputDirectory / "*.aab")
        .DependsOn(Restore)
        .Executes(() =>
        {
            var droid = Solution.GetProject("Peerless.Expeerience.Droid");

            MSBuild(_ => _
                .SetTargetPath(droid)
                .SetTargets("Rebuild")
                .SetConfiguration(Configuration)

                .SetArgumentConfigurator(a => a.Add("/t:PackageForAndroid")));

On Azure Devops, it doesn’t seem to find the dotnet core sdk at all even after installing:
