As you may be aware, Project Reunion is Microsoft’s latest
project to make app development easier for Windows 10. Project
Reunion is being developed to bridge the gap between two
important app platforms (APIs) for Windows 10 – Win32 (desktop)
and UWP (modern Store apps).
In essence, Project Reunion will allow developers to access
both Win32 and UWP APIs when developing their apps for Windows
10. It also means that Windows 10 will no longer prevent Win32
developers from taking advantage of Microsoft’s newest API
Today, Project Reunion has hit the first big milestone and
version 0.5 is now available for
developers. Version 0.5 of the project enables access to the
latest technologies, such as WinUI 3 (which includes shiny new
rounded corners) and improved text rendering.
rounded corners for Start Menu and other system elements
will require Windows 10 Sun Valley Update, Microsoft’s current
goal is to make Project Reunion-based apps work on all
supported versions of Windows, including version 1809 (the
October 2018 Update), April 2019 Update and newer.
Project Reunion will improve the app experience on Windows 10
explained by Microsoft during the Ignore 2021 conference,
Project Reunion isn’t a new app model, new platform, and nor is
it a different set of APIs. As the name “Reunion” implies, this
project is all about bringing Win32 and UWP closer so that the
divide doesn’t exist.
Over the past few years, Microsoft has ignored Win32
development and focused more on the UWP platform.
Project Reunion will undo past mistakes and make it easier for
Win32 developers to use the UWP APIs that they want. It will
also make the APIs behave the same across both platforms.
“We’re taking the APIs that shipped in UWP and making them
available to Win32,” Microsoft said.
Project Reunion 1.0 is currently scheduled for Q4 and Microsoft
is also introducing support for WinUI 3 and WebView 2 to
integrate modern UI and web contents into Windows apps
It’s also worth noting that the
Alarms & Clock app was recently updated with WinUI 3-like
design and we’re also expecting improvements for other
first-party apps in the coming months.
