WinUI is finally truly open sourced! github.com/microsoft/mi...

Morten Nielsen @dotmorten.xaml.dev · 15/08/2026

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:

Working on a little e-paper side-screen to remind me of upcoming meetings, tasks, etc. Fully configurable from a Microsoft.UI.Reactor tray app. WIP source code here: github.com/dotMorten/Si... #WinUI

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

Out of space. Perhaps time to stop collecting these and move on… #mvpbuzz

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++.

Added two portable 17” monitors to the sides of my wide screen monitor. Did I overdo it? Maybe. Do I care? Nope 🤣

Morten Nielsen @dotmorten.xaml.dev · 11/06/2026

Project templates are now available for Microsoft.UI.Reactor. Run 'dotnet new install Microsoft.UI.Reactor.ProjectTemplates' to install, then 'dotnet new reactorapp' to build your first project. #winui

Experimenting a bit with Microsoft.UI.Reactor and ArcGIS Maps SDK for .NET. Making some progress getting things hooked up... #WinUI

Morten Nielsen @dotmorten.xaml.dev · 28/05/2026

You can now create a WinUI app as a single file-based app!

This makes no sense to me. Those are almost all non-UI APIs that are just as much available with WPF as they are with WinUI, since they don't ship with either, but comes with the normal Windows API bindings.

Needed a 360° panorama image viewer control for both WPF, WinUI, and .NET MAUI. That was a fun little side project using WPF's 3D Controls, Direct3D from C# in WinUI, OpenGL in Android and SCNView on iOS/Catalyst github.com/Esri/arcgis-...

Did another little #WPF vs #WinUI test. Started a stopwatch at the beginning of main() and stopped it when the root UI element was loaded. WinUI: Average 170ms, WPF: 450ms. (Running on ARM64 12-core Snapdragon X)

Morten Nielsen @dotmorten.xaml.dev · 23/04/2026

Did a fun little comparison between #WPF and #WinUI. Simple app with ListView and 100 items in it. Code as close as possible to each other. The WPF memory usage after a bit of scrolling is just nuts

The only change in the WinUI binaries is a rename of the new IXamlPredicate API:

Nice. You forgot a spot though. Not even sure what you mean about rounded corners?

Crazy view of the moon and Earth from Artemis II right now

Looks like the only new API since preview 1 is the new Xaml Conditions, and then a bunch of removed AI APIs. You can see the full spec here: github.com/microsoft/mi...

I did a thing. If you know you know #WinUI

Morten Nielsen @dotmorten.xaml.dev · 24/03/2026

We're finally getting `dotnet new` project templates for #WinUI: www.nuget.org/packages/Mic...

There’s something cool about having your own custom made PCBs

Finally got around to setting up an OpenClaw instance. This is quite useful!

What's up with Copilot lately? It's gotten extremely annoying.

Some good progress on MQTT and the UI for my home made pool controller (Right is VNC over to the raspberry pi running it all, left Home Assistant)

Morten Nielsen @dotmorten.xaml.dev · 10/02/2026

Even Microsoft Authenticator is in on this 6-7 thing

Morten Nielsen @dotmorten.xaml.dev · 09/02/2026

Well that sucks but explains all the BSODs. Sucks my 6 year old memory is now more than twice as much as I paid for it back then 😢

Just got the high voltage lid left to print on my home made pool controller. Starting to look super clean

Tried my hand at designing and ordering a custom PCB for this project. Got sick of working with prototype boards. This was a fun little thing to try.

Some progress on my pool pump controller running on Raspberry Pi with Uno and .NET 10: ✅ Pump monitored and controlled. ✅ Read temp water sensor. ✅ Expose data to MQTT. Next is Chlorinator monitoring and control relays for actuators

This new side project is a mess of ideas …

Morten Nielsen @dotmorten.xaml.dev · 26/01/2026

Weekend project: Was annoyed that getting my pool pump connected so I can remotely turn it on/off would cost me over $3000 plus labor so I said F it, using .NET and @platform.uno I can do that cheaper, better and with MQTT integration into @home-assistant.io
