KCP C#
KCP C# version. Thread safe, no alloc at runtime, no pressure on gc
...The project uses unsafe code and unmanaged memory internally to reduce garbage collection pressure, which is important for real-time systems. It supports Span<byte>, external buffer rental, and a generic KcpCore<Segment> architecture for performance-focused implementations. The library is partly thread-safe, allowing concurrent Send and Input calls while restricting concurrent Recv and Update calls for correctness. It is useful for game networking, real-time communication, and other latency-sensitive C# applications that need reliable delivery over UDP.
