The new ThemeResource API is such a nice improvement. Love seeing the pace of progress lately. Keep pushing forward!

Use #WinUI 3 and got two minutes? Please share your experience with the Microsoft.UI.Xaml/WinUI repository: forms.cloud.microsoft/pages/respon...

Cool idea. Only thing I wonder about is that sure it’s 8x faster but perf table is showing micro seconds so is the difference even noticeable? Aren’t there bigger fish to fry?

Tip of the day: Ask Copilot to add EventSources to your source code and have it also write a skill how to use them to track lifecycle and performance issues. It makes the agent so much better at diagnosing issues going forward.

Thanks! I gotta be better a remembering to add that

Isn’t what the power shell script does the same thing as what the skill would do? It basically already have the skills

WinAppCLI reached v0.6.0 for building WinUI applications, with new package signing through Azure and faster app creation. Command line first Windows app dev is a sign of where Microsoft wants the workflow to live. #Windows #WinUI #Microsoft

However if it’s open source I encourage you to clone the repo and direct the agent at the folder - it’ll do much better at discovering and using APIs

Morten Nielsen @dotmorten.xaml.dev · 21/08/2026

It constantly does this already. I know this because I’ve moved my nuget cache folder and it keeps failing at finding the right location

Hehehe yeah that was a hint 🤪

Agreed but probably outside my scope of work

I'm excited to share that today is my first day at Microsoft, joining the Windows Developer Platform team! I'll be working on the Windows App SDK and working with developer communities to help evolve the platform and make building great apps on and for Windows even better. #winui

Found a much better robust alternative to XAML. No more annoying angle brackets - Everyone knows indentation is the best way to define app structure. I considered JSON but who wants more punctuation? #winui #maui #wpf #xaml

There's a nice little enhancement to #WinUI code generator now that simplifies overwriting the standard main method with your own code:

Windows App SDK v2.4.0 just landed. This one looks to just contain new APIs for the search APIs and some bug fixes (no new #winui APIs). API diff: omds.xaml.dev/WinAppSDK_v2... Release notes: github.com/microsoft/Wi...

Windows App SDK v2.3.2-experimentalA just landed. Among a few other new APIs, super proud to see my PR that adds Window sizing in dips is now in the SDK! #WinUI

You’re actually supposed be to replace the white with the blue ones but don’t like that 🤣

I had my agent look at the diff and breakdown the performance optimizations in this release: gist.github.com/dotMorten/fe...

Since when is 808kb app size an issue? That’s still tiny. Now look at new Outlook which will easily eat 1Gb of memory because of all the webbrowser processes

No being able to read and scroll through a large file is app feature. What Plummer built is barely a usable notepad imho. That the new notepad is slightly larger is not the major issue of Windows. It’s all the PWA apps they’re shipping that is resource hogs

Handling large files, different encodings, multiple tabs, zoom, remember contents across restarts just to name a few

To be fair the notepad in windows 11 has numerous much needed features added

Playing around with some custom DirectX rendering inside Microsoft.UI.Reactor and ended up with some fun 360° samples. All 100% C# code in #WinUI. No XAML, no C++.

Guess which one is classic Outlook and which one is new Outlook
