The ULM.gen project is a framework that help building and customizing source-code generators from a UML model expressed as XML documents, using generation templates. It also provides tools for synchronization with UML modelers such as IBM Rational Rose.
This project aims to produce a form editor like the ones in Visual Studio and SharpDevelop. It is intended to be used as a control for end-users of your application to allow them to create customised forms.
The designer persists forms to XML.
