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 @merriemcgaw.bsky.social and I showed it at #dotnetconf on stage - live #vibecode 'd!

First Form in #WinForms I did completely with #CopilotEdits. If you have _THAT_ not checked out, do it. It is AMAZING! Like, completely. No code blocks written by me - just tweaked little things which were WinForms specific and the LLM wouldn't know.
What this is? Well...more to come. ;-)

Hey #winforms devs!
In #dotnet 9, we've introduced WinForms specific #Analyzers to help you guide with tricky WinForms situations. We got those both for #csharp and #visualbasic. And not only are we planning to add more over time-you can also get engaged:

WinForms: Analyze This (Me in Visual Basic) - .NET Blog
Your WinForms code might have issues—maybe an Async call picked the wrong overload, or it’s leaking data into resource files. Time to call in a code-shrink! So, WinForms, Analyze This!

So…over the holidays I thought I would ramp up my WebDev skills which are from, what, 1998? I was aiming for #dotnet #blazor. Question is, would using #aspire be an overkill? Or even support the (re)learning process? Consider me a 72-year old German CDU politician to assess my WebDev skill set… 🤷♂️
