MessagePack-CSharp

Leverages dynamic code generation, JIT optimizations, and zero-allocation techniques, achieving up to 10x faster serialization than other C# serializers, as demonstrated in benchmark graphs.

Integrates LZ4 compression directly into the serialization pipeline with Lz4BlockArray support, reducing payload size without significant performance loss, ideal for network-heavy applications.

Serializes a wide range of types including primitives, collections, immutable objects via SerializationConstructor, and interfaces through Union attributes, covering most C# use cases without extra configuration.

Targets .NET Standard 2.0 with optimizations for .NET 8+, Unity, and Xamarin, supported by AOT code generation and Roslyn analyzers for restricted environments.
