| Delight users with modern UI | Access new platform features | Backwards compatible |
|---|---|---|
 Powerful WinUI 3 UI |
 Localization + power status + more |
 Down to Windows 10 1809 |
...and more, without having to rewrite your app!
- Use your current installer (no requirement to use MSIX, but there are reliability/security benefits to using MSIX!)
- 100% additive (only add what you need, leave the rest of your app as-is)
- Works with Win32, WPF, WinForms, and UWP apps
Plus, it's backwards compatible to Windows 10 October 2018 Update (build 17763 / version 1809)!
Packaged MSIX desktop apps can use the 0.5 release now!
Some notes about 0.5...
- Requires using MSIX (1.0 won't require MSIX)
- Only includes WinUI 3 / Text rendering / Localization
- To use WinUI 3, it's best to start a new app project and, if useful, copy any existing code/business logic from past projects into the new project (in the future, XAML Islands will enable incrementally adopting WinUI 3)

Project Reunion aims to work on supported versions of Windows. Right now we support down to build 17763 (version 1809/October 2018 Update) of Windows 10. Wherever possible, we'll use techniques like 'polyfills' and custom implementations to do the heavy lifting for you and make sure your app works across Windows versions and devices. In the future, there may be a couple APIs that are dependent on new OS features (like new Action Center functionality), however we will do our best to ensure this is the exception and not the norm, and provide reasonable fallbacks when possible.

Discussions can be about any topics or ideas related to Project Reunion. For example, you might start a Discussion issue to see if others are interested in a cool new idea you've been thinking about that isn't quite ready to be filed as a more formal Feature Proposal. -
Make a feature proposal
What components do you want to see in Project Reunion? For example you can propose a new API on an existing type, or an idea for a new API. It's fine if you don't have all the details: you can start with a summary and rationale.
Over time, we will add Project Reunion code and samples into this repo and provide code contribution/developer guidelines.
