I will be second to recommend http://www.7-zip.org/sdk.html LZMA SDK, but it's not ZIP.

2. It's FAST on decompression
3. It has fully managed implementation
4. It's much better compressing than ZIP/RAR
5. It has very small footprint
6. It can work as a stream

Answer 6

Try System.IO.Compression.DeflateStream.
