Go to Derived Symbols
This command gets the list of all derived symbols for a type or a member and lets you navigate directly to one of them, down the inheritance hierarchy. If you are looking for actual implementations and not interested in intermediate steps of the inheritance chain, use Go to Implementation.
You can invoke this command from the Solution Explorer, from the File Structure window and other tool windows. If necessary, you can navigate in the opposite direction with the Go to Base Symbols command.
Navigate to derived symbols
Place the caret at a symbol in the editor or select the symbol in a tool window.
Press Alt+Control+B or choosefrom the main menu. Alternatively, you can press Control+Shift+A, start typing the command name in the popup, and then choose it there.
If the symbol has only one derived symbol, ReSharper will navigate to it directly.
If necessary, you can change the default behavior so that even the single symbol is displayed in the list. To do so, clear the Go to Base/Inheritor if there is only one... checkbox on the page of ReSharper options (Alt+R, O).
If the symbol has several derived symbols, they will be listed in a drop-down. The list may contain items in both bold and regular font. Bold indicates that an item has direct inheritance, while the regular font is used for indirect inheritance.
You can do one of the following:
Click the desired item to open it in the editor.
Select the desired item by pressing Up and Down and then press Enter to open it in the editor.
Start typing to filter results. Note that you can use CamelHumps here. If necessary, press Esc once to clear the filtering.
To show the matched items on the type dependency diagram, press Alt+Num+ or click Show on Diagram .
If there are members in derived classes that hide the member you're navigating from, such members are displayed as strikethrough:
When a type or a member has inheritors in the current solution, you can see it by the presence of a special icon (for example, ) that appears to the left of the declaration. You can click the icon to expand the list of derived symbols and navigate.
To detect inheritors of members on the fly and to display the corresponding gutter mark, ReSharper has to perform some calculations. Large inheritance hierarchies with the combination of weak hardware could lead to some performance degradation. If this is the case, you can clear the Show gutter navigation marks for implemented and overridden members checkbox on the page of ReSharper options to avoid complex calculations and thus improve performance.
On the other hand, on-the-fly calculation of type inheritors is much cheaper performance-wise and therefore is not disabled.
