I'll be speaking at the .NET Developers meetup in Tokyo on June 9th!

1/N I vibe-coded a C compiler that targets .NET IL. It can build unmodified PureDOOM into a .NET app that runs on both .NET 10 and desktop framework.

.NET 11 (NativeAOT) on Windows ARM32!!

Found Sokol.NET - C# bindings for the Sokol crossplat gfx framework. If you haven't heard about Sokol, it's a C header-only library to build crossplat gfx/audio apps (games). Sokol.NET wraps it for C# (Win/Linux/Mac/Android/iOS/WASM). Tons of samples. Also native AOT: github.com/elix22/Sokol...

Nice article on the state of native AOT with the release of .NET 10: code.soundaranbu.com/state-of-nat...

Sorry but the off-color corner of the new Word icon looks like a compression artifact when taskbar is set to small (and sorry but small & never combine & show labels is the only correct taskbar configuration on Windows, this is not macOS).

Cosmos Gen3: The NativeAOT Era and the End of IL2CPU? valentin.bzh/posts/3 #dotnet #osdev #csharp

After #flareon11 challenge 7, I got inspired to build tooling for #dotnet Native AOT reverse engineering. As such, I built a #Ghidra Analyzer that can automatically recover most .NET types, methods and frozen objects (e.g., strings). 👉https://blog.washi.dev/posts/recovering-nativeaot-metadata/

I've published the third part of my series of articles about writing a .NET garbage collector in C#. In this one, we add a helper method to inspect the objects in memory, learning about thread modes and the DAC. minidump.net/writing-a-ne... #dotnet

After writing a profiler in C#, I've now published the first of a series of articles about how use C# to... write a .NET Garbage Collector. #dotnet minidump.net/2025-28-01-w...

Writing a .NET Garbage Collector in C#  -  Part 1

First part of a series of articles about writing a .NET Garbage Collector in C# using NativeAOT. This part sets the expectations and setups the project, dealing with the first difficulties.

I published part 5 of my "Writing a .NET profiler in C#" series. All the foundations built in the previous articles have been moved to a library named Silhouette. In this new article, we finally have everything we need to write an actual profiler. minidump.net/writing-a-ne... #dotnet

Finally had time over the holidays to realize a long-standing dream of mine: a hex editor that knows about the PE file and .NET metadata format. You can click any byte and it will show you which data structure it is in the tree. Every byte is covered. The parser is at github.com/KirillOsenko...

got my custom sokol-backed c# game engine zinc compiling to wasm using nativeaot-llvm! and for anyone else headed in a similar direction, I spent some time writing up what it took, what bugs I encountered, etc! give it a read here #gamedev #zinc #csharp kylekukshtel.com/csharp-wasm-...

Forgot that the docs are here: www.nuget.org/packages/siz.... To install, simply `dotnet tool install sizoscope --global` but you'll want to read the docs to find out how to create the files this tool operates on.

1/3 New version of sizoscope, my tool to analyze size of .NET native AOT executables, is out! It can now show you sizes of some of the blobs within the executable just to give a more complete picture.

Thanksgiving is approaching in the US and that means time with family. People in your family were presented with this dialog in the past and probably just clicked the button Google wanted them to click. Ask them if they want to browse the web, or if they want web to browse them.

If you're into low level .NET, you should give @xoofx.mastodon.social.ap.brid.gy a follow!

JIT compiled .NET will often be faster than AOT compiled .NET thanks to dynamic PGO. But AOT compilation has some tricks up the sleeve too. In .NET 9, the TechEmpower JSON benchmark ends up a bit faster with AOT.

Last time I got free stuff from Microsoft as an employee was when I got a T-shirt for shipping .NET 6.

Microsoft created a unique purple and blue Surface colorway for employees that worked on the Copilot+ PC launch. This won’t be available to purchase, just something for some Microsoft employees. It looks great in person 👍

The .NET native AOT compiler used to have an unsupported mode where it broke all reflection for size savings. I added the mode in 2019 when Hello World was 4 MB and with broken reflection only 1 MB. It was a good goalpost. In .NET 9 they're both ~1 MB: goalpost reached! github.com/dotnet/runti...

.NET conf 2024 is this week and I'll go deep into native AOT on Friday!

1/N When the .NET native AOT compiler compiles your app to native code, it needs to perform whole program analysis to figure out all parts of your program. Reflection kind of throws a wrench in that because some reflection is really hard to reason about statically.
