.NET Framework 1.1 does not have the Compression namespace.
Recently I was searching for the compression namespace in .NET framework 1.1...but didn’t find it... that’s because actually the .NET 1.1 does not have the compression namespace. So, thought to make a note on that. The .NET framework 1.1 does not contain any general purpose libraries for compression. But it’s possible to use free third part libraries. So, here are 2 links I got from friends.

But .NET framework 2.0 contains the System.IO.Compression namespace. :)
