Documentation: The XAF Advantage | XAF App Architecture

I stumbled across DevExpress and tried out the XAF framework. To say I was blown away would be an understatement! I was simply amazed at the ability to define my data model and have the basic UI for CRUD created automatically. With every new feature I discovered, I was more amazed. David Landry

Model-Driven UI

Generate your data model of any complexity from an existing database using XAF wizards, or define the model manually in code or using the visual scheme designer. XAF automatically generates a final and fully customizable UI based on your data model. This includes everything you need: various data forms, menus and app navigation, reporting, charting, analytics – powered by award-winning DevExpress controls and libraries. When user requirements or the context of use change, the data model changes accordingly and so does the supporting UI.

After using XAF for some time now, I cannot even think of building a complex WinForms or Web application without it anymore. It is a very powerful and customizable business applications framework built upon the best components on the market. Dario Cavallaro

I used Visual Studio before I knew about XAF but the way XAF manages database construction itself is very fast so I can spend more time thinking about the business process itself rather than the database and software structure. Beautiful framework. Julio Cachay
