root object
An object at the top of a hierarchy maintained and used by the .NET garbage collector to determine whether objects are addressable by your program. A root object and all of its referential parent and descendant objects are known collectively as a reference tree.
In the Object Reference Graph, the top-level .Root. node is a "virtual" node that represents the total amount of memory allocated to all objects in the reference tree. It is not an actual object.
See also .Root. and reference tree in the glossary.
