A pure C# portable class library (PCL) implementation of high performance LZ4 compression algorithm, with streaming interface (System.IO.Stream derived). It includes a High Compression (HC) codec variant, which is slower than the standard LZ4 codec, but provides a better compression ratio. This... More information

Extension methods providing high performance deep copy capability for of arrays of common value types - currently: byte, char, short, int, long, and their unsigned brethren where applicable. Considerably faster than Array.Copy - and it's also faster than Buffer.BlockCopy in most... More information

A set of extension methods for doing bitwise manipulation such as endianness (bytes<-->integral types) and rotation. Endianness-related functionality: short, ushort, int, uint, long, ulong : conversion between (to and from) individual items of these and byte arrays, and between arrays of any of... More information

High performance classic ring/circular buffer (with optional .NET BCL System.IO.Stream interface) for byte data. Packaged as a portable class library (PCL). Asynchronous I/O from streams is supported to boost performance. Supports concurrent reading and writing, and overwriting (optional).
