Why use Roslyn Source Generators instead of Reflection in game tools:

Reflection inspects properties at runtime, generating runtime allocations and boxing.

Our Source Generator automatically writes pure C# binary serialization methods during compilation:

[GenerateBinaryPacker]
public partial struct PlayerStatePacket {
    public int PlayerId;
    public float Health;
    public Vector3 Position;
}
// Generator automatically emits: public void Serialize(Span<byte> dest) { ... }

Zero runtime reflection overhead, 100% compatible with NativeAOT!

Source generators are the cleanest way to serialize game network packets in C#. Big vouch.

Compile-time code generation is the future of .NET.
