Does anyone know if it is possible to target newer previews of .NET Core 3 when targeting the Visual Studio 2019 Preview image? I'm trying the following YAML:

image: Visual Studio 2019 Preview
- ps: dotnet --list-sdks

which generates a long list of old .NET Core versions + this one from 3.0:


I would like to be able to target preview 7 (3.0.100-preview7-012821) or maybe even preview 8.

    I second that question, any insight or help to get a newer version of the .Net Core 3 preview SDK would be greatly appreciated.

    A bit late now, but might be useful for other versions. You can install your own version of .NET Core using the dotnet-install script. For instance:

      _DOTNET_VERSION: "3.0.100-preview7-012821"
      - ps: "[Net.ServicePointManager]::SecurityProtocol = 'Tls12'"
      - ps: Invoke-WebRequest -OutFile .tmp\dotnet-install.ps1
      - ps: if ((-Not (Test-Path .tmp\dotnet\dotnet.exe)) -or (((.tmp\dotnet\dotnet.exe --version) -Join '') -ne $Env:_DOTNET_VERSION)) { .tmp\dotnet-install.ps1 -Version $Env:_DOTNET_VERSION -InstallDir .tmp\dotnet } else { $Env:path = $Env:APPVEYOR_BUILD_FOLDER + "\.tmp\dotnet\dotnet.exe;" + $Env:path }
