Microsoft has released Windows App SDK 2.5 Experimental, an update for the native Windows 11 framework. This research-stage release adds built-in TableView and Chart controls while fixing specific memory leaks in WinUI.
Why it matters
By expanding native controls and improving memory efficiency, Microsoft aims to reduce developer reliance on web-based alternatives for Windows 11 applications. This move reflects a broader strategic focus on improving the quality of first-party and native software experiences.
The 2.5 release introduces native TableView controls, which now support grouping, sorting, filtering, and keyboard-based resizing. These additions are designed to resolve long-standing feature gaps that previously pushed developers toward external web wrappers.
The players
Microsoft
The enterprise software giant responsible for the Windows operating system and its associated development frameworks.
WinUI
The native user interface framework used to build Windows 11 applications.
The details
The SDK update targets memory growth issues occurring during storyboard creation—a mechanism for defining UI animations and state transitions—and theme resource resolution. By implementing native TableView and Chart controls, the framework allows developers to render data-heavy interfaces without importing third-party libraries. This change simplifies the internal architecture for Windows 11 applications, which use WinUI, the platform's native user interface library, for layout and component management.
Timeline
September 29, 2026: Windows App SDK 2.5 Experimental released.
May 2026: The Build 2026 developer conference occurred.
The Tech Race
This release marks a significant step in the effort to modernize the Windows shell by migrating core UI elements to WinUI. It directly competes with the ease of development provided by cross-platform web frameworks, aiming to reclaim developer preference for native Windows architecture.
Developers building for Windows 11 can begin testing these native TableView and Chart features immediately in experimental environments. While not yet ready for production deployment, these improvements will eventually simplify the workflows for creating data-centric Windows applications.
The takeaway
Microsoft is aggressively closing the feature gap between native WinUI and web-based development tools to improve performance. Developers should monitor the transition of these experimental controls into the next stable SDK version to plan for future UI updates.
