Your Compact Framework "Phrase of the Day"
People often ask for a brief description that compares the functionality of the .NET Compact Framework to the full .NET Framework. A few years ago, the company I work for (Progress Software Corporation) used a term to describe their web-based server-side programming language (SpeedScript, part of the WebSpeed environment) in comparison to their standard 4GL programming language - "extended subset". I think this term applies well to the .NET CF.
The .NET CF is a subset of the full .NET Framework, with many of the base classes not included. At the same time, the .NET CF is tailored, or "extended" to provide functionality that is specific to the Windows Mobile platform. Therefore, the .NET CF is an "extended subset" of the full .NET Framework.
There you have it - now you have a really brief answer to common question... ;-)
