Yep, FFI. GC/DOM/Web API integration is in the eventual plans. https://github.com/WebAssembly/design/blob/master/GC.md https://github.com/WebAssembly/design/blob/master/GC.md You want .NET on bare metal? Implement it on x64, ARM, MIPs and maybe PPC. You want .NET in the browser, implement it on wasm. You want Java in the browser, implement it on wasm. You want BEAM in the browser, implement it on wasm. You want Parrot in the browser, implement it on wasm. What you are not going to do is to get Google, Apple, Mozilla and Microsoft to all agree on any of those ILs.
