Is there some flag or light that I can see on CI artifacts to make sure this all kicked in?

If you look at a signed build, like xamarin-android/main:

https://devdiv.visualstudio.com/DevDiv/_build/results?buildId=7029241&view=artifacts&pathAsName=false&type=publishedArtifacts

Microsoft.NET.Sdk.Android.Workload.net8.0.multitarget.vsman has:

  "packages": [
    {
      "id": "Microsoft.Android.Sdk.net8.34.0.0-preview.1.74",
      "version": "34.0.0.0",
      "type": "Msi",
      "machineArch": "arm64",

I don't know if you can see that until this is merged? Do PRs build .vsman files?

Do PRs build .vsman files?

I don't think so, but I will check it once merged to confirm.

@mattleibow the build is done from where this merged, what artifact contains the .vsman file?

@pjcollins you might know.

@jonathanpeppers I think https://devdiv.visualstudio.com/DevDiv/_build/results?buildId=7036408&view=results is the pipeline you'll want.

@Redth @mattleibow this looks right to me:

  "packages": [
    {
      "id": "Maui.Sdk.net7.7.0.0-ci.net7.7216",
      "version": "7.0.0.0",
      "type": "Msi",
      "machineArch": "arm64",

How do we backport to .NET 6 and 7?
