How integrations work

Reactive SO uses Unity’s assembly definition versionDefines to automatically detect installed packages. When a supported package is installed, the integration code becomes available without any manual configuration.

{
    "versionDefines": [
        {
            "name": "com.cysharp.r3",
            "expression": "",
            "define": "R3_SUPPORT"
        }
    ]
}

The extension methods are located in Runtime/External/R3/ directory and compiled only when R3 is present.
