MessagePack CSharp
MessagePack-CSharp is a high-performance binary serialization library for .NET applications that converts object graphs into the MessagePack format. It functions as a C# data serialization toolkit and a polymorphic binary encoder capable of handling abstract classes and interfaces using union keys to identify concrete derived types.
The library provides a binary format transcoder to transform binary data into human-readable JSON for debugging. It supports ahead-of-time formatter generation to avoid runtime overhead and implements LZ4 binary compression to reduce the size of serialized data.
The project covers a broad range of data handling capabilities, including typeless object serialization, binary stream sequence reading, and string interning to reduce memory allocations. It also incorporates security measures such as deserialization depth limiting to protect against resource exhaustion attacks.
Features
- Binary Deserialization - Reconstructs structured object graphs from raw binary blobs using both typed and dynamic deserialization.
- MessagePack Serializers - Provides a high-performance binary serialization implementation specifically for the MessagePack format in .NET.
