ilspy-cli Agent Reference

Rust CLI for .NET decompilation using ILSpy (ICSharpCode.Decompiler). Binary name: ilspy.

Architecture

Rust CLI (clap) ──netcorehost FFI──► C# Bridge DLL (IlSpyBridge.dll) ──► ICSharpCode.Decompiler

• In-process: .NET runtime hosted inside the Rust binary via netcorehost crate
• No server/daemon: each command loads the assembly, runs, exits
• Data exchange: JSON strings over FFI function pointers with [UnmanagedCallersOnly]
• Key differentiator: single-method decompilation (--type T --method M), which ilspycmd cannot do

Requirements

• .NET 8 runtime (loaded by netcorehost at runtime)
• .NET 8 SDK (build time only, for dotnet publish of the C# bridge)
