Your .NET Conf proposal does not need to explain everything. One useful lesson is enough. The Community Days CFP closes tomorrow, Oct 6. Remote 30-minute talks, including Q&A. Tell them what you built, learned, or would do differently: https://sessionize.com/dotnetconf-community-2026/

Missed yesterday's .NET MAUI Community Standup? GnollHack is a real cross-platform game built with .NET MAUI. The team joined us to share their development journey, challenges, and lessons learned. Watch it back here 🎮 https://www.youtube.com/watch?v=_1iLdE7d1jo

We're live! A real game built with .NET MAUI and available on Steam 🎮 Join us as the GnollHack team shares how they built their cross-platform roguelike, what they learned, and what got difficult. Bring your questions! https://www.youtube.com/watch?v=_1iLdE7d1jo

A .NET MAUI app... err, game. Available on Steam?! 🎮 Tonight's .NET MAUI Community Standup goes inside GnollHack. Hear how the team built a cross-platform roguelike with .NET MAUI, and bring your questions. Live at 20:00 CEST: https://www.youtube.com/watch?v=_1iLdE7d1jo

.NET MAUI on iPhone Duo anyone? 👀

Your app feels slow. The process you are profiling might be innocent. This Visual Studio walkthrough separates CPU work from waiting, then finds 50 ms added to every streamed update. https://devblogs.microsoft.com/visualstudio/today-i-will-find-hidden-latency-across-a-distributed-net-application/

That thing you learned the hard way? It might be a .NET Conf talk. Community Days CFP is open: remote 30-minute sessions, Nov 12-13. .NET 11 demos are preferred, but any useful .NET topic can be considered. Submit by Oct 6: https://sessionize.com/dotnetconf-community-2026/

Long press is built into .NET MAUI 11. This sample covers MinimumPressDuration, AllowableMovement, GestureStatus, commands, touch position, tap coexistence, and a two-finger iOS/Mac example. https://github.com/dotnet/maui-samples/tree/main/11.0/UserInterface/Gestures/LongPressGesture

Which bug has a habit of waiting until after publish to show itself? Trimming, Native AOT, linker behavior, environment-specific configuration, signing, or path casing? What would you add to the list?

Friday .NET tip: scanning text for the same substrings repeatedly? Build SearchValues<string> once, then use ContainsAny. Need the position? Use IndexOfAny. .NET 9+, Ordinal or OrdinalIgnoreCase only. https://learn.microsoft.com/dotnet/api/system.buffers.searchvalues.create?view=net-10.0</string>

I'm live on .NET Unboxed right now, showing some of the new .NET MAUI 11 bits 🎁 The team is opening .NET 11 RC1, with Jon Galloway, Daniel Roth, Mads Torgersen, and more. Come hang out: https://www.youtube.com/watch?v=5fvi7m1QxIY

〰️ HAPPENING TODAY - .NET Unboxed: .NET 11 Release Candidate 1!! 〰️ Join the team LIVE as they show off their favorite features in .NET 11 in this release party for .NET 11 RC 1!! See you here at 11AM PT ➡️ msft.it/63320aXhLE

C# 15 preview lets break and continue target an enclosing labeled loop. That can remove a state flag or awkward goto from genuinely nested control flow. For a simple loop, keep it simple. https://devblogs.microsoft.com/dotnet/dotnet-11-preview-7/

Per-solution themes make Visual Studio 2026 windows easy to spot. The useful part is settings.VisualStudio.json beside the solution. Commit it for team settings, or keep it personal with .gitignore. https://devblogs.microsoft.com/visualstudio/stop-alt-tabbing-into-the-wrong-visual-studio/

Tomorrow I'm joining .NET Unboxed for .NET 11 RC1 🎁 I'll show some of the new .NET MAUI 11 bits, alongside Jon Galloway, Daniel Roth, Mads Torgersen, and more. Thursday, 20:00 CEST / 18:00 UTC https://www.youtube.com/watch?v=5fvi7m1QxIY Which MAUI 11 bit are you most curious about?

A GitHub Actions job that only reads Dependabot alerts should not get unrelated token access. Use vulnerability-alerts read at job level. Once you specify permissions, omitted ones become none. https://docs.github.com/actions/reference/workflows-and-actions/workflow-syntax#permissions

A green managed test run does not prove the Native AOT publish behaves the same. Keep the fast lane. Add one representative native test lane. Verify test count and outcomes. A passing subset is still a false green. MSTest 4.4: https://devblogs.microsoft.com/dotnet/mstest-source-generation/

Content exclusions now carry into agentic work. The GitHub Copilot app and Copilot CLI keep excluded files out of context. Available for Copilot Business and Enterprise. https://github.blog/changelog/2026-09-02-content-exclusions-generally-available-in-copilot-app-and-cli/

Stop creating every XAML resource at startup. .NET MAUI 11 XAML Source Generation turns dictionary entries into factories and creates them on demand. The benchmark shows up to ~8× faster dictionary initialization. No XAML rewrite. https://github.com/dotnet/maui/pull/33826

The code is written. The PR still has review feedback, failed checks, and a merge conflict. VS Code 1.136 adds Agent Merge (preview). It can keep working through those blockers until the PR is ready. Which one would you hand off first? https://aka.ms/VSCode/136

MAUI Day Skopje is 12 days away 🇲🇰 September 17. One free, in-person day focused on .NET MAUI, with sessions, speakers, and plenty of time to talk with the community. If Skopje is within reach, go check it out: https://mauiday.net/skopje/ Anyone here joining?

September is here. What is the one thing you want to ship before the month is over? A feature, a release, an experiment, or that tiny fix that keeps getting bumped. What are you building?

We're live! .NET MAUI meets GitHub Copilot Canvas 🤝 Join David Ortinau, Dominik Titl, and me as we inspect running MAUI apps, analyze layouts, record interactions as tests, and use captured evidence to diagnose failures. Watch now: https://www.youtube.com/watch?v=A5Pr5N999tc

Tomorrow at 20:00 CEST / 18:00 UTC: .NET MAUI meets GitHub Copilot Canvas 🤝 Join David Ortinau, Dominik Titl, and me to see a tool inspect apps, analyze layouts, record interactions as tests, and capture evidence when things fail. https://www.youtube.com/watch?v=A5Pr5N999tc

AI is everywhere. Useful #AI is harder to find. That’s why the AI sessions at #UCP26 focus on what really matters. Meet the speakers: 👉 @jfversluis.dev, @konradkokosa.bsky.social, Karl-Henrik Nilsson, @chrisnas.bsky.social, @kajetanduszynski.bsky.social 👉 prague.updateconference.net/en/2026/sche...

I like this C# 15 preview feature: `closed` hierarchies. The compiler knows every direct subtype, so your switch can be exhaustive without a fallback. Add another subtype later and the switch is flagged for you. https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/closed

.NET Conf returns November 10-12! 🎉 Three days, free and online, with the official launch of .NET 11. The schedule is still coming together. For now, save the dates. What are you hoping to see this year? https://devblogs.microsoft.com/dotnet/dotnet-conf-2026/

What is your .NET MAUI paper cut? Not the huge feature request. The small recurring annoyance you hit every week, work around again, and think: surely this should be easier by now. Some answers might become future demos or issue investigations. What’s yours?
