WingetUI 3.0 Alpha 0

This is the first release of the brand-new WingetUI, based on C#.NET + WinUI3.
This release contains the base WingetUI application, completely rewritten from scratch.

However, the following features are NOT available yet:

• Importing and exporting packages
• Installed package backups
• Package tags
• Adding and removing sources (installed sources are listed)
• The API that communicates with WingetUI Widgets
• The API that allows WingetUI to open when a package was shared to you (you can still share packages)
• Viewing package details (The interface works, but it will show no data).
• WingetUI ran as administrator will crash when opening a File/Folder picker
• The built-in WingetUI autoupdater. You may want to subscribe to this repository to get notified when a new release is available.

The rest of features are expected to work as they did on WingetUI 2.2.0 and prior.
This beta release may be unstable. It is not intended to be daily-driven.
