Class hierarchy view

Languages:

The Class Hierarchy View displays more information about the hierarchy of a class. It consists of a hierarchy tree and a list of its class members. To open the Class Hierarchy of a class, right-click the class name and select Show Class Hierarchy (or press F4 ). You can also use the Code Lens above the class declaration.

The members list is populated for whichever class you select in the Class Hierarchy. Clicking any element in the class hierarchy tree or members list opens it in a preview editor (note that the title in the editor tab is shown in italics). Double-clicking an item will open a permanent editor. You can right-click any item to open the declaration in the editor or to show the class hierarchy for that element instead.
