The audience for this manual is an experienced OpenEdge ABL developer who is familiar with user-interface design and implementation.
Although the Visual Designer uses .NET objects to implement user-interface elements, you do not need to be familiar with .NET to understand this manual or to use the Visual Designer. The architecture of the Visual Designer allows you to treat .NET objects as if they were native ABL objects.
You should, however, have a general knowledge of object-oriented coding practices and concepts. In addition, you should be familiar with object-oriented programming in ABL, as described in OpenEdge Development: Object-oriented Programming.
