"All COM interfaces use reference counting. This means that whenever an interface is assigned to a variable, it’s reference count is updated. Whenever the variable goes out of scope, the reference count is automatically decreased. When the reference count reaches zero, usually the instance of the class that implements the interface, is freed.”
Shouldn’t destroy be called in this example when TestScope exists?
TScopeObject = class (TInterfacedObject)
destructor Destroy; override;
scope := TScopeObject.Create;
