I've decided to aggregate all utilities/extensions I use across different C# projects into a single source-only package. I'm surprised there were so many, but it totals 130 individual files. Feel free to copy-paste what's useful to you. github.com/Tyrrrz/Power...

Also want to take an opportunity to shout out a project of mine that's always been in the shadows: github.com/Tyrrrz/PolyS... It provides polyfills for ~500 BCL APIs, allowing you to write modern C#/.NET code on targets as old as .NET Standard 1.0 and .NET Fx 3.5. I use it in all my libraries ✨

Hey folks! Today I’m launching N‑Studio — the successor to ScreenToGif. It’s a passion project that’s been years in the making, and I hope you enjoy it as much as I’ve enjoyed building it. nicke.tech/n-studio

I built an interactive guide on how GPS works! perthirtysix.com/how-does-gps...

Anyone with synesthesia here? What color is the foreach statement? I'd be curious what color people would pick, I'm sure it's very individual.

"[The administration's characterization of Direct File] has it completely backwards. It is a calculation that only makes sense if you do not value the time and money of citizens, but regard the government doing anything to help the public as a burden."

I am hoping to drop Newtonsoft.Json from VSTest (which powers test running in .NET in: dotnet test / VS Test Explorer / C#DevKit) Please help me test it: github.com/microsoft/vs... #dotnet

Is anyone I know at Microsoft hiring right now? I have a good candidate (not me!)

Do you ever want to quickly measure code execution time while debugging? Just released DebugTimer — a simple source-only .NET package for development-time performance diagnostics. #dotnet #csharp github.com/fiseni/Debug...

It's a wrap! #ILSpy 10 is finally here, grab the bits at github.com/icsharpcode/... (as well as VS marketplace + nuget.org + Store (submitted))

I returned to my structured editor roots a little bit and prototyped a scrollbar that shows the statement structure in method bodies. Also a document outline tree where statement structure is visible for larger methods. This way you can visually distinguish methods by their "shape".

A long time ago I wrote an analyzer to flag usages of async void

Suppose we were to beam a 1024x1024 bitmap into interstellar space (or send a probe with a golden plate) and we wanted to describe how advanced our current level of math is. It's clear aliens won't understand our language or notation. What images wouldn't be possible 30-40 years ago?

I've been working on a rebuild of #chordle for a couple of years now. Spare time projects can be brutal, and Chordle is a big ol' project, but I'm really happy with how the new editor is working out - drag and drop of chords in both #chordpro and chords above text! #avaloniaui

Just shipped a massive release of dotnes! A testament to vibe coding for fun. Many samples working now! github.com/jonathanpepp...

if you’d like to volunteer take a look at codeclub.nz

The final preview of #ILSpy 10 is ready for download github.com/icsharpcode/...

How getting paid on pkgstore works 💰 1. Connect Stripe (one click) 2. Create a listing with a price 3. Push your packages 4. Buyers subscribe via Stripe Checkout 5. Money hits your Stripe account That's it. pkgstore.io 📦

Selling a NuGet package shouldn't require stitching together a feed server, payments, credentials, and a storefront. pkgstore does all of it — Stripe storefront, auto NuGet feed, credential mgmt. Buyers use standard dotnet CLI. No custom tooling. 📦 www.pkgstore.io

This video was a complete joy to make. Here's a short preview, but next time you're looking to sit down for 45 minutes of math and art, take a look at the full version on YouTube: youtu.be/ldxFjLJ3rVY

Just blogged: My @nuget.org packages hit a quarter-billion downloads. Just a number; I’m not sure it means much, but I turned it into a short note on NuGet, OSS, and the community. www.devlead.se/posts/2026/2... #nuget #dotnet #oss

Delete your global.json. It's not useful for anything and just adds friction. How many times I've cloned a repo, build, it doesn't build with an obscure error, delete global.json, it builds just fine. Whatever the purpose was, it's not worth it. My goodness. So much unnecessary pain.

I've been using the wsb CLI for the most part. For a project where I use sandbox a lot, I'll write a wsb file with my mapped folders, and I'll have a simple function to launch the sandbox and run my startup script from a mapped folder. Jeff has a module too www.powershellgallery.com/packages/Win...

Published a new module called AvaloniaUIShell, (the world's first?) cross-platform desktop GUI framework for PowerShell. github.com/mdgrs-mei/Av... It's using the same mechanism as WinUIShell and takes care of all threading and non-blocking UI operations. #PowerShell

can you believe it I found an actual Amazon bug: 1. buy item A and deliver to address 1 2. buy item B and deliver to address 2 3. in the history, click on item A and say Buy again 4. in the history, click on item B and say Buy again 5. UI shows address 1 6. items actually get delivered to address 2

making a GUI IDE in 2026 is an increasingly meditative act

This video makes me extremely happy. Dianna Cowern (AKA Physics Girl) was diagnosed with long COVID, with symptoms similar to ME/CFS. She is basically bedridden. Seeing her active and excited is amazing ❤️ youtu.be/B3m3AMRlYfc?...

I published part 8 of my "Writing a .NET Garbage Collector in C#" series. The subject this time is interior pointers: what are they, and why are they so challenging for the GC. minidump.net/writing-a-ne...

MCP server of the day: mcp-binlog-tool. Rather than manually generate and inspect msbuild binary logs, why not have GitHub Copilot just build and analyze it? Those binlogs contain a *LOT* more information than what you see in the terminal output: github.com/baronfel/mcp...

Bound trees (internal Roslyn representation of executable code) can now be displayed on .NET Lab. This includes ref safety escape scopes. Makes investigation of compiler bugs easier. #dotnet #csharp #roslyn #dotnetlab

Ignore extreme takes. Stay curious. Keep learning. Keep working. It’s going to be OK.
