Assembly: EnvDTE (in envdte.dll)
Returns the GUID representing the CATID of the object as a string.
The CATID is typically specific to an implementation of an object.
Also, the values of code model elements such as classes, structs, functions, attributes, delegates, and so forth can be non-deterministic after making certain kinds of edits, meaning that their values cannot be relied upon to always remain the same. For more information, see the section Code Model Element Values Can Change in.
