PowerShell DSC Resources for WinGet

[denelon]

Description of the new feature / enhancement

I would like to be able to use PowerShell DSC to install and configure WinGet.

Several issues have made mention to challenges associated with getting WinGet installed (or in a valid state) on different Windows SKUs or environments:

• can't launch winget  #2040
• install in Windows-Sandbox #2081
• Install WinGet from terminal / PowerShell #2222

@cdhunt also made a PR with a PowerShell script to help with this challenge:

• Add bootstrap script #2474
• Install Error - Fail to detect Microsoft.UI.Xaml dependency #2230
• How-to guide for installing Microsoft.DesktopAppInstaller non-interactively #2434

A couple of mentions have also suggested PowerShell DSC:

• Winget fails to open source package in elevated session using admin account that cannot log on locally #698 (comment)
• Check if Package installed #291 (comment)

Proposed technical implementation details

As we are nearing the first release of WinGet PowerShell modules and cmdlets, this would be aligned with that same effort.

• Add Native PowerShell Support #221

Naming things is hard:

• PowerShell DSC Resources for WinGet #2697

We should consider the options for making this work in the System context in terms of getting "WinGet" on the system, and then when the user logs in, the actual "registration" for the user is "faster".
