 If you're looking for the fastest binary serializer for DotNet known to Git-kind, look no further.  HyperSerializer is up to ***18x faster than [MessagePack](https://github.com/neuecc/MessagePack-CSharp) and [Protobuf](https://github.com/protocolbuffers/protobuf), and 11x faster than [BinaryPack](https://github.com/Sergio0694/BinaryPack)***, with roughly equivelant or better memory allocation. Simply install the [Nuget package (Install-Package HyperSerializer)](https://www.nuget.org/packages/HyperSerializer/) and serialize/deserialize with just 2 lines of code.
