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 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...

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.

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.
