An independent implementation of Google's protobuf binary serialization format, protobuf-net approaches the problem-space with common .NET coding styles, but retaining the high performance, dense output and cross-platform interoperability. It's compatible with most of the .NET family, including .NET 2.0/3.0/3.5, .NET CF 2.0/3.5, Mono 2.x, Silverlight 2, etc.

In particular (compared to most implementations), it allows:

  • both code-first and contract-first development
  • mutable objects
  • inheritance

Oh, and it is pretty darned fast too.
