Tada. Completed app!
What's new in WinForms for .NET 10 and Visual Studio 2026. This is impressive that Copilot created this WinForms app.
Form Customization APIs
Dark Mode
Proper async/await support for cross-thread UI updates!

Hi Klaus and Merrie! WinForms presentation app using GitHub Copilot! \o/
Also, Merrie with the Veteran's Day shoutout 👏🏿.
This is awesome. With the proper prompting context, and guardrails, it's going to follow through.

Demo of Foundry Local SDK incorporated and running within Win UI!
It's awesome to see this slick example of sending a prompt into a local model and parsing the data from it in a particular format. RIGHT within the app. \o/.

I've been using this locally to test, experimented with a chat provider implementation in VS Code and currently have it implemented in the app I'm posting this from lol
Get started with winget install Microsoft.FoundryLocal
And play with models that run on NPU!

Nice! Its running the benchmark, analyzing the perf trace and it found a top insight to address.
It's fixing the issue :O.
Interesting point to remember, you have to still understand whats going on because it returned something that wasn't the best fix the first time.

First thing's first, How do we optimize in the real world?
- Do I know the issue? If not, run profiler. If yes, generate/run benchmark, optimize code, loop
