@cxiao yes, this indeed is the main point. It's almost artificially limiting yourself.

Though in fairness, I do think we as developers can also do better making our libraries more available to other ecosystems. Python is here to stay, whether we like it or not. Maybe these libraries just need a pypi package that people can just pip install.

@dmetzgar obfuscators have existed long before trimming and readytorun were introduced, so should work. You just may have to tell your obfuscator not to rename certain objects in your app if you rely on reflection finding these objects by name (usually through configuration or obfuscator sdk attributes).

Over the past couple years, I have come to know the #dotnet platform pretty well, from a developer's and a #reversing standpoint.

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).

Recovering Metadata from .NET Native AOT Binaries

Ever seen a binary that looks like a .NET binary based on its strings, but .NET decompilers are not able to open them?
