wasmcloud uses tinygo not the standard go compiler for webassembly component support tinygo compiles a large subset of go to webassembly with a much smaller binary footprint toolchain tinygo with

not yet support the wasm component model tinygo targets wasip2 directly and produces much smaller binaries making it the current path for go developers building wasm components tier 2 stable toolchains these languages have stable component model toolchains that can produce components compatible with wasmcloud you can build components manually and run them with wash but there are no wash project templates or wash dev integrations yet c net componentize dotnet is a bytecode alliance project that compiles net applications to wasm components using nativeaot toolchain componentize dotnet
