"Copilot doesn't work with #WinForms."
Yeah? - Watch me prove you wrong. 🧵
Robert Green and I used the WinForms Expert Agent in #VisualStudio and also #Copilot CLI to build a live WinForms + EF Core 10 client for some old, old SQL Database on Visual Studio Toolbox - including one unscripted feature we genuinely didn't think would work.
ALFKI is back. 👇

I wrote a blog post recently about the #WinForms Expert Agent, which enables the design of UIs to be prompted. But it's a field story, about #Copilot and my 82-year-old Mom, who got sort of "stranded" at a customer. I got quite some reactions, many... devblogs.microsoft.com/dotne…
... many as personal messages. One, however - let's put it that way - moved me, and made me contemplate a lot. It was a real conversation. "Did you read it?" - "Tried 3 times." - "Tried? Too long, too boring?" - "No, I stopped 3x when it started to scare me too much".
About #AISlob... Two options, I've NEVER 😏 been affected by that. a) I am an excellent, extraordinary, perfect natural language prompter. b) My code is yet slobbier anyway, so I wouldn't notice. Q: When affected, how much was Slob mitigateable by improving your System Prompts?
Hey #WinForms Devs. Tell you something. So, my 82-year-old-Mom's Time Study software GPF'd (yes, she still does Consulting gigs occasionally) - at a customer! The plan: A new WinForms App as a quick Ersatz for the Time Recording. Could Copilot help? devblogs.microsoft.com/dotne…

We merged a C# 15 feature into .NET 11 preview 2: collection expression arguments.
Allows specifying creation arguments for a collection expression: `List<string> names = [with(capacity: 10), ... elements ...];`
Spec: github.com/dotnet/csharplang…

.Net Blog: Introducing #CSharp Expert and #WinForms Expert—two experimental #CustomAgents designed to help #DotNet developers write cleaner, smarter code using #GitHubCopilot. Learn how these agents enhance productivity and expertise: is.gd/QRLYQs
Nice! Without having personally tested it - ComponentOne picking up/supporting #WinForms #DarkMode is really cool to see! Makes me happy, if we can further standardize it, because it's more than taste. It's really #A11Y!
The new ComponentOne maintenance release is live! Full .NET 10 support across WinForms, WPF, Blazor, WinUI & MAUI.
Bonus: WinForms dark mode is now built‑in. Want the details? Read the blog: bit.ly/4r13m6C

What's new in #WinForms for #visualstudio and #dotnet 10? Well, a lot! The best: WinForms is one of the first disciplines in VS which gets a dedicated context agent for Copilot! And we showed it at #dotnetconf on stage - live #vibecode 'd!

Finally, the video is published, and I get to sleep at 2:30 am. 😴
Probably an hour earlier than expected.
I hope y'all enjoy the video. See you tomorrow for day 2 of #dotNETConf.

My first run through of using custom agents in #GitHubCopilot and @code with the new WinForms Expert!

#AI isn't replacing Devs - it's unlocking the clutch ones!
#ADHD and good tooling have always been a winning combo. Add AI, and you get outcomes no one saw coming.
It's adapting, thriving, and turning chaos into innovation!

And if you want to know why it's very much alive and kicking - read that Reddit thread and in it what innovations we did in #WinForms in the last years!!
When a Reddit thread about "reviving WinForms" pulls in 350+ comments, it tells you something.

The #ADHD cat is out of the sack. @MadsTorgersen and I talk about our journey "late ADHD diagnosis" - in Episode 1 of #SharpAndUnfiltered
youtu.be/bTsGKiuZwXA?si=Ky4S…
And we did a 2nd one - discussing issues like late tasks, anxiety, RSD, hyper- and not focusing, distractions...
What do @MadsTorgersen & I share
(besides a love for curly braces)?
Turns out, something that is a feature, not a bug.
And it's called ...👉 #ADHD.
In the pilot of #SharpAndUnfiltered, we talk the back and forth to clarity, symptoms, and superpowers.

Mark the day, folks!
Not what you expect, but worth to watch.
Well...we think, don't we... don't we @MadsTorgersen?
😎
WE can't wait to see what's in store... Hear what interesting goodness @MadsTorgersen and Klaus Loeffelmann (@loeffelmann) have to share. Coming September 25th.
Don't forget to subscribe to the Microsoft Developer (cont) msft.it/l/6019sobhf
At a #microsoft campus cafe, just recently.
@MadsTorgersen and Klaus @loeffelmann talk
Sharp & Unfiltered.
Not what you expect.
Definitely worth watching.

#sharpandunfiltered - Spread the word!
Hey #winforms devs! In #dotnet 9, WinForms got some new cool features for consuming modern APIs with `Control.InvokeAsync` and other async APIs. Check out the blog post here and spread the word!
