Right-click on a class -> Show in symbol browser.
Right click on the class in the browser, Derived Classes...
In "Derived classes", under "PUBLIC" are listed 7 *functions*.
All of these functions are entries in the MyLibrary.XML file that the C# build generates.
It is not finding actual derived classes.
Why is it listing functions?
The XML looks like:
<?xml version="1.0"?>
