Dictionary :: typeDefinitionCount - Number of type definitions

The property provides the number of type definitions currently stored in the internal dictionary. The internal dictionary contains built-in type definitions and application type definitions, which have been read so far, i.e. the internal dictionary usually does not provide all type definition.

While running a dictionary, the number of type definitions may grow, but type definition loaded once are removed, only, when the internal dictionary (dictionary node) will be destroyed.
