MsgPack.Light is a lightweight MsgPack serialization library.

Key features

  • Performance
  • .Net core compatability
  • Extensibility
  • Simple usage


Simpliest way to start using ProGaudi.MsgPack.Light is to install it from NuGet.


Serialization to bytes array:

var bytes = MsgPackSerializer.Serialize(value);


var value = MsgPackSerializer.Deserialize<string>(bytes);

Your type serialization/deserialization:

If you want to work with your own types, first thing you need - type converter. Example of Beer type converter you can find here. Then you should create create MsgPackContext and register your converter:

var context= new MsgPackContext();
context.RegisterConverter(new BeerConverter());

And then you can serialize:

var bytes = MsgPackSerializer.Serialize(beer, context);

And deserialize:

var beer = MsgPackSerializer.Deserialize<Beer>(bytes, context);


To build MsgPack.Light you have to install dotnet SDK version 1.0.0-preview4-004233 or higher (you can find corresponding build on dotnet/cli project. After dotnet is installed, run following commands:

git clone
cd MsgPack.Light
dotnet build -c Release -f netstandard1.4 src/msgpack.light/msgpack.light.csproj
dotnet build -c Release -f netcoreapp1.1 tests/msgpack.light.tests/msgpack.light.tests.csproj
dotnet test -c Release --no-build tests/msgpack.light.tests/msgpack.light.tests.csproj

MsgPack.Light should built and all test should be passed.


  • Serialization performance is comparable with msgpack.cli
  • Deserialization performance 2-3 times faster
  • MsgPack.Light works best if a data reside a memory (_*Array benchmarks).
  • Perfoming some IO operations, performance is suboptimal, but comparable with MsgPack.Cli (*_Stream benchmarks).
  • More details can be found here.



  • Code-generator for field-based converters, we will support array and map modes.
  • Possible optimizations with IO handling and asyncing our API.
