Solution Designer Design Area
The design area can be used to design classes and enums. The "classes" and "enums" tabs at the top left of the design area can be used to switch between the two.
The design area is split into two main areas. Down the left hand side is a list of either classes or enums. Down the right hand side are the properties of the currently selected class or enum. In-between the two areas is a splitter bar that can be dragged left and right to adjust the width of the two areas.
The properties area on the right hand side is also broken down into two main areas. The top area shows the main properties of the class or enum. The bottom area displays more detailed properties broken down into sub-areas using a set of tabs.
For more information see the classes and enums pages.
