Building custom XAML control panels

One of my favorite XAML Control primitives is the Panel class. It's what drives Grid, StackPanel, Canvas and many many other controls that contains a set of other controls, and controls layout the children out in the view.

So in my second twitch stream, I walked through creating a custom panel that lays out controls in a grid-like manner, without having to do all the row and column definitions. It mainly focuses on the Arrange and Measure steps in the layout life-cycle, which applies to both WPF, UWP and WinUI (or even Silverlight for that matter ;-). And just for fun I used the latest WinUI 3.0 Alpha release (but it really doesn't matter as the concepts are the exact same - only namespaces differs).

Building your own version of WPF - Live edition

As a follow-up to my blogpost on compiling WPF back when it was still in preview, I tried something new: Live-streamed cloning, compiling and using a local build of WPF in a new app, and make some (evil) modifications to WPF. Even got to submit a PR to the WPF documentation while going though this.

I've been inspired a lot be many others who've started to live-code on Twitch. It's quite interesting to see their thought process and approaches to solving problems - things you never see in a polished 45min conference presentation where everything is prepped and (hopefully) nothing goes wrong. There's quite a lot to learn from seeing people using tools, shortcuts, tricks and tips to solve their problems.

This was a surprising amount of fun, and I'll definitely be doing this again (and hopefully fix some of the issues I had doing this live). I'm prepping some various level 200-400 topics on XAML development, like custom panel and control development, and hope you'll join me. All of these concepts will apply to both WPF, UWP and WinUI, but I figured let's live dangerously and use the latest WinUI Alpha (and we'll log any issues we find as we go).

Here's the recording from yesterday. Feedback and suggestions, as well as ideas for topics to cover would be highly appreciated.
