Example – depend on VCLibs

"msix": {
  "packageDependencies": [
    {
      "name":       "Microsoft.VCLibs.140.00",
      "publisher":  "CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S=Washington, C=US",
      "minVersion": "14.0.30704.0"
    }
  ]
}

Example – depend on WinUI 2.x

{
  "name":       "Microsoft.UI.Xaml.2.8",
  "publisher":  "CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S=Washington, C=US",
  "minVersion": "8.2310.30001.0"
}

If the framework package is not present at install time, Windows refuses to install your MSIX. Distribute the dependency separately or via the Microsoft Store.
