icsharpcode/ILSpy ? reverse-engineered prompt

Build me a cross platform .NET assembly browser and decompiler that lets me open a compiled app or library, inspect its types, methods, properties, and metadata, then view the decompiled C# in a clean explorer style interface. I want search, easy navigation between related types, history, bookmarks, and support for opening from disk and from running processes on Windows. It should also handle whole project decompilation, ReadyToRun binaries, and BAML to XAML decompilation. Make it work as a desktop app on Windows, Linux, and macOS, and also include a command line version I can run from terminal. If it makes sense, add support for plugins and a Visual Studio extension too. Keep the UI simple and polished, and if you need to check anything tricky, look up the current docs online.
