"New Breakthroughs for Developing and Deploying Client Applications
The .NET Framework 3.5 SP1 includes the new .NET Framework Client Profile -- the fastest and easiest way to deploy applications for Windows. With .NET Framework 3.5 SP1 and the .NET Framework Client Profile, developers can more easily deploy client applications thanks to an 86.5 percent reduction (197 MB to 26.5 MB) in .NET Framework size. This means that end users will be able to download and install Windows-based applications significantly faster than before. The .NET Framework Client Profile also makes it possible to extend the improved download and installation experience to existing .NET applications.
Developers now can quickly and simply deploy new and existing rich-client applications to a broader audience."
