Exploring Type Hierarchy
With JetBrains Rider, you can investigate the inheritance hierarchy of types from your solution and from referenced libraries. You can see both base types and inheritors of the selected type and navigate to any of them with a mouse click. For any node in the hierarchy, you can view all or only polymorphic members in the preview pane.
To investigate hierarchy
Locate the desired type in the editor editor or expand it in the Solution Explorer.
Press Ctrl+E, H or choosefrom the main menu. Alternatively, you can press Ctrl+Shift+A, start typing the command name in the pop-up, and then choose it there.
Examine type hierarchy in the dedicated tab that adds to the Hierarchy window.

In such case you can start typing a part of symbol's name or its CamelHumps abbreviation and JetBrains Rider narrows down the set of elements in the window:
To rebuild a hierarchy for an intermediate node
In the hierarchy tree view, select the desired node.
Press Ctrl+E, H or right-click the node and choose Base on This Type.
