NetWasm: C# WebAssembly Output Now Smaller Than Rust
- NetWasm v0.8.0 reduces C# WASM binary size significantly by introducing precise Compact GC
- In the print-42 benchmark, NetWasm is 10.9% smaller raw and 20.4% smaller with Brotli compared to Rust
- The project is an independent .NET platform implementation, avoiding dependencies on desktop CLR, Mono, or dotnet.js
