“Client-only Framework subset” in Visual Studio 2008

The .NET Framework Client Profile setup contains just those assemblies and files in the .NET Framework that are typically used for client application scenarios. For example: it includes Windows Forms, WPF, and WCF. It does not include ASP.NET and those libraries and components used primarily for server scenarios. Approx. 26MB in size, and it can be downloaded and installed much quicker than the full .NET Framework setup package. For more info Click here
