I'm trying dev containers in Visual Studio Code. There's something I don't understand. I'm trying one of the examples: vscode-remote-by-dotnet. Everything installed, the Docker container built and started. I opened a new terminal in VS Code, and in the welcome line it says to me:

vscode ➜ /workspaces/vscode-remote-try-dotnet (main)  

Does this mean that this terminal is running in the container, right? In this terminal I ran:

dotnet run  
info: Microsoft.Hosting.Lifetime\[14\] Now listening on: [http://localhost:5000](http://localhost:5000/)  
info: Microsoft.Hosting.Lifetime\[0\] Application started. Press Ctrl+C to shut down.  
info: Microsoft.Hosting.Lifetime\[0\] Hosting environment: Production  
info: Microsoft.Hosting.Lifetime\[0\] Content root path: /workspaces/vscode-remote-try-dotnet  

now I check (in the host terminal):

PS C:\\Users\\vitaly\> netstat -ano | findstr 5000
TCP 127.0.0.1:5000 0.0  
PS C:\\Users\\vitaly\> tasklist | findstr 28508  
Code.exe 28508 Console 7 126?088 K  

as I understand it, port 5000 is opened by the code.exe process and not by Docker...

docker port 056f6dc9896c

shows nothing at all (056f6dc9896c is the container ID).

Why is that?
