I've look at this document

About performance .Net and Managed C++
What I want to do is writing Managed C++ proxy class to improve the performance of my desktop app which use ArcObject.
I've successfully created a test project (visual c++, CRL class project) and reference ESRI dll.
And able to use ArcOcject interfaces and classes. But what I noticed is that I can't use IPointPtr which presents in the example in the document above.
I can use IFeatureWorksapce but not IFeatureWorkspacePtr
So I think what I'm doing now is incorrect.
Could you please guide me what to do to able to use IFeatureWorkspacePtr
Thanks in advance.
