The eXpressApp Framework by Developer Express is a powerful instrument for creating business applications quickly and easily. A strong modular architecture allows for platform independent domain specific extensions. Examples of typical applications include business/sales/CRM systems, projects, documentation, HR and training class management, and many others. The currently supported target platforms are Windows Forms and ASP.NET 2, and our open architecture allows extensions of either of these platforms as well as the introduction of completely new targets (WPF support is part of our plans for the future).
