Commonwealth Online — Server & Host

The dedicated server and its host GUI for Commonwealth Online (Fallout 4 multiplayer). Everything now builds on one .NET 8 toolchain.

Components

• server/ — the dedicated relay server (CommonwealthOnline.Server, a .NET 8 console app). Run it with server/start.sh / server/start.bat, or CommonwealthOnline.Server serve.
• host/ — the Avalonia cross-platform host GUI: start/stop the server, edit config, watch the log, and manage players (kick/ban). Replaces the former Qt/C++ host.

Quick start — server

cd server
./start.sh          # Linux / macOS
start.bat           # Windows

Needs the .NET 8 runtime (or the SDK for a source checkout). Allow TCP 7777 (and optionally UDP 7778 for LAN discovery) through the firewall. 0.0.0.0 is a bind address, not the address players join.

Quick start — host GUI

dotnet run --project host/CommonwealthOnline.Host.csproj

Build

dotnet build server/CommonwealthOnline.Server.csproj -c Release
dotnet build host/CommonwealthOnline.Host.csproj -c Release

The Qt/C++ host and its CMake build were retired in favour of the Avalonia host. SETUP.md / DEVELOPMENT.md / DEPLOYMENT.md are from the Qt era and are pending a refresh.
