WasmGC

[cyraid]

Now that version 34 is pretty much here(?), will there be support WasmGC? Reading blog post it looks like it arrived in wasmtime with version 27.

Benefits would be smaller wasm modules needed from what I read? I would definitely be interested in this!

Unfortunately the Wasm GC proposal as it stands does not have enough for dotnet GC

[cyraid]

@yowl In what way if I may ask? Could you give me a bit more information? :) (and perhaps they'll have what they need in post-v1?) maybe we can voice our input on what it needs in the webassembly spec?

dotnet/runtime#94420
Has a good technical description of the current state of play.

Thanks @yowl for the link. That's the kind of conversation I was looking for.

@yowl Am I missing something or does this entire discussion apply to .NET code compiled to WASM, which is not the same thing as running something else with its own GC needs, compiled to WASM?

Concretely, I have implemented a small language which compiles to WASM, the compiler is written in .NET but I don't need the .NET runtime in any way, shouldn't it be possible to run my lang (compiled to WASM or WAT) from .NET test code via wasmtime dotnet?

Correct, I was referring to using WasmGC as a replacement for dotnet's GC. Your own language can do as it likes.
