When I use the wasmtime xxx.wasm command to run the .NET web application and specify the program listening port through --tcplisten localhost:8000, the console always prints ：

info: Microsoft.Hosting.Lifetime
       Now listening on: http://localhost:5000

But the real port of the web application is not 5000

The command I use is as follows：

wasmtime webapp.wasm --tcplisten localhost:8000
info: Microsoft.Hosting.Lifetime
      Now listening on: http://localhost:5000

I suspect dotnet simply reports localhost:8000 as default for the lack of a wasi api to retrieve the actual address and port it listens on. --tcplisten gives the wasi program a socket on which it can call sock_accept. Nothing more, nothing less AFAIK.

The wasm application cannot get any socket stats for pre-opened sockets, as sockaddr is not defined in WASI, so it always reports 0.0.0.0 port 0. The string you are seeing must be some fallback.
