.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).

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...

Cool project: a hypervisor-based emulator for Windows x64 user-mode executables. One of my first thoughts upon seeing it - "I wonder if it's also possible to call the Windows hypervisor APIs from C#". github.com/x86matthew/W...

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.

1/4 Life hack: uninstalling the Notepad app in Windows 11 gives you back old notepad.exe that starts faster and uses less memory. This Notepad is going to be a bit cursed and registry hacks are needed to uncurse it. 👇

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

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...

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.

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

Different ways .NET makes sure your code is done fast.

1/ There is now a 4 MB portable ZIP version of my Sizoscope tool (built with C# and WinForms) that runs on Windows and Linux. While WinForms in the .NET 9 nightlies is still not fully trim-safe or AOT-safe it didn't require too many hacks to get native AOT working with Sizoscope.

For my next trick I'm going to build a 64 MB self-contained game in C# and then shrink it to 1936 bytes in 10 steps. Read all about it in my latest article: migeel.sk/blog/2024/01...

Wrote an article on how I built a bare-metal bootable "game" in C#: migeel.sk/blog/2023/12...

Made a bare metal bootable maze "game" in C# as a demo of what's possible with bflat's zerolib. Anyone interested in reading a write-up of how I did it? Source here: github.com/MichalStreho...

I've released v8.0 of bflat - my take on C# with a native-first compilation model. If you're on Windows you can grab it with `winget install bflat`. Linux version in the repo releases tab.

Wrote a new article: Top 3 Whole Program Optimizations for AOT in .NET 8

New version of Sizoscope, my tool to inspect size of .NET native AOT binaries is out. If you're on .NET 9, the tool will now show you "frozen objects", a frozen part of the GC heap that the compiler generated ahead of time. They're the result of executing your code ahead of time.
