The code sample for CRecipeThumbProvider defines a function HRESULT CRecipeThumbProvider_CreateInstance(REFIID riid, void **ppv) without explaining its purpose or otherwise making easy to understand why it exists. I thought that maybe function names ending in _CreateInstance had some special meaning to the Windows shell, but was not able to find any such information.
The code sample should have a comment justifying the existence of the function.
