As of today’s releases of our Windows Forms products, we have dropped support for VS 2003 projects and .NET 1.1 builds of our component libraries. At this point, VS 2008 has been out for some time and anyone doing Windows Forms development should be on .NET 2.0 or later.
The latest maintenance releases now have both Visual Studio 2008 and Visual Studio 2005 sample projects included.
All the component libraries are built targeting .NET 2.0. Please note that libraries that target .NET 2.0, can be used in any later .NET framework as well, such as .NET 3.0 or 3.5.
