A cross-platform library for efficiently serializing objects into a variety of formats.

• Simple and effective support for backward compatibility when adding new serialized object members.

• Stream-based API doesn't require the entire object to reside in memory.

• Supports a variety of serialization formats, including JSON, XML, Bencode, and PBON, with a single API.

• Available as a Portable Class Library, so it can be used with Mono, Xamarin.iOS, and Xamarin.Android as a cross-platform solution.

• Supports transmitting objects between platforms (regardless of processor endianness, for example).

• Supports inspection of the underlying byte stream, which enables scenarios such as digital signing.

• Suitable for extending into higher-level abstractions, for example, a messaging protocol.
