SYSK 19: Confused about Forward and Backward Compatibility? Then read this...

Forward compatibility means that an application can be compiled and run on both later and earlier versions of the .NET Framework. Can your application, compiled using VS2005 (.NET 2.0) run without any problems on .NET 1.1? If yes, it’s forward compatible.
