winui 3

On June 3, 2026, Paul Thurrott published an account of using Microsoft’s new Windows Development Skills and the WinApp CLI with Claude Code to generate a native Windows 11 WinUI 3 app from a plain-language prompt. The result was not a miracle, but it was more important than a demo: it showed...

Paul Thurrott published a June 3, 2026 post showing a “vibe-coded” WinUI 3 native Windows 11 app, turning a small developer experiment into a useful snapshot of where Microsoft’s desktop platform now stands. The point is not that one app proves the Windows renaissance has arrived. It is that...

At Build 2026, Microsoft expanded its Windows 11 native-app campaign by releasing WinUI-focused AI agent tooling for GitHub Copilot and Claude Code, previewing WinUI 3 templates, and tying the work to a broader push to rebuild core Windows experiences natively. The announcement is not merely...

Paul Thurrott used Microsoft’s new Windows Development Skills preview with Anthropic Claude Code after Build 2026 to generate a native Windows 11 Notepad-style app using WinUI 3, the Windows App SDK, and the WinApp command-line tool in roughly 48 minutes. The result was not a miracle, but it was...

Microsoft used Build 2026 in Seattle to push developers toward modern native Windows 11 apps, pairing WinUI 3, Windows App SDK tooling, AI-assisted coding agents, and new developer hardware into a broader campaign to make Windows feel faster, more coherent, and less like a shell around web...

Microsoft is replacing decades-old Windows 11 dialog boxes in 2026 by rebuilding them with WinUI 3, starting with a redesigned Run dialog in Insider builds and reportedly moving next through file-copy, properties, and common file dialogs across the Windows shell. The project is not cosmetic in...

Microsoft is working through Windows 11’s older dialog boxes and rewriting them in WinUI 3, with the file copy dialog already completed internally and the common file dialog next on the list, according to remarks from Microsoft design executive March Rogers this week. That matters because...

Microsoft is preparing to roll out smooth resizing fixes for WinUI 3 apps in summer 2026 after acknowledging that some modern Windows 11 applications can visually tear and expose black edges while being resized, even as older UWP apps often handle the same motion more gracefully. That is a small...

Microsoft is responding to years of Windows 11 performance complaints by accelerating its WinUI 3 native interface work in May 2026, publishing early File Explorer and Notepad benchmark gains while also adding command-line templates and AI-assisted tooling for Windows App SDK developers. This is...

Microsoft said in May 2026 that it has cut the time spent in WinUI 3 code during File Explorer launch by about 25 percent, alongside large reductions in allocations and function calls, as part of a broader effort to make Windows 11 feel faster. That is not just a framework tuning story. It is...

Microsoft is testing performance work for Windows 11’s WinUI 3 interface stack in May 2026, with reported File Explorer launch improvements including 41 percent fewer memory allocations, 63 percent fewer transient allocations, 45 percent fewer function calls, and 25 percent less time spent in...

Microsoft has confirmed in May 2026 that it is optimizing WinUI 3 as Windows 11’s forward-looking native interface framework, using File Explorer and Notepad as benchmark apps and reporting double-digit reductions in launch-time allocations, calls, and WinUI execution time. The promise is not...

Microsoft is preparing Windows 11's native interface to feel faster in 2026, using its Windows K2 responsiveness push to tune WinUI 3, reduce File Explorer launch overhead, and pair framework fixes with short CPU boost behavior known as Low Latency Profile. The interesting part is not that...

Microsoft has begun optimizing WinUI 3 itself as part of its Windows 11 performance push, with early File Explorer launch benchmarks showing fewer allocations, fewer transient allocations, fewer function calls, and less time spent inside WinUI code. That is the more important story behind the...

Microsoft has officially shown a rebuilt Windows 11 Run dialog, now available as an optional modern interface in preview builds, replacing the decades-old Win32-era box with a C#/WinUI 3 version that opens in a reported median 94 milliseconds. That is not the sort of change that sells laptops...

On May 1, 2026, Microsoft began testing a rebuilt Windows 11 Run dialog in Insider Experimental builds, replacing the decades-old Win32 surface with an opt-in C# and WinUI 3 version that Microsoft says opens in a median 94 milliseconds. The number should have been a quiet engineering footnote...

Microsoft is working on a modern WinUI 3 replacement for File Explorer’s legacy Properties dialog in Windows 11, according to findings in recent Insider builds reported on May 4, 2026 by Windows Latest. The change appears to move one of Windows’ most stubbornly old-fashioned surfaces out of the...

Microsoft has finally put a name to one of Windows 11 File Explorer’s most noticeable quirks: the reason Home and Gallery scroll smoothly while ordinary folders still feel stepped is that they are not built the same way under the hood. The modern views ride on WinUI 3 and the Windows App SDK...

Microsoft is preparing one of the most consequential Start menu revisions Windows 11 has seen since launch, and the significance is bigger than a fresh coat of paint. The new direction points to a native WinUI 3 foundation, more explicit user control over layout, and a clearer attempt to answer...

The Windows 11 Start menu may finally be getting the kind of flexibility users have wanted since launch, and that alone makes this one of the more meaningful interface changes Microsoft has tested in years. Early reporting indicates a broader redesign that would let people hide major sections...
