Empty wasiconsole on dotnet v9.0.100-rc.2.24474.1 fails to run

[queil]

Trying to dotnet run an empty wasiconsole app. I get the following:

WasmAppHost --runtime-config /work/wasiconsole/bin/Debug/net9.0/wasi-wasm/AppBundle/wasiconsole.runtimeconfig.json
Running: wasmtime run --dir . -- dotnet.wasm wasiconsole
Using working directory: /work/wasiconsole/bin/Debug/net9.0/wasi-wasm/AppBundle
Error: failed to run main module `dotnet.wasm`

Caused by:
    0: component imports instance `wasi:http/[email protected]`, but a matching implementation was not found in the linker
    1: instance export `fields` has the wrong type
    2: resource implementation is missing

Am I missing something or version 0.2.1 is not implemented yet? Can only see 0.2.0

More details about state of WASI in .NET 9 in #106350 (reply in thread)

The error message from wasmtime is telling you that the app wants to use wasi:http but you didn't give wasmtime the necessary permissions. try adding --wasi http directly to wasmtime or --extra-host-arg=--wasi --extra-host-arg=http to dotnet run

And yeah, we are not going to fix WASI experiment in Net9.
