Vanara.PInvoke.Shell32 and IStorageProviderCopyHook

[Blair88]

Is your feature request related to a problem? Please describe.
I'm currently trying to implement a cloud sync engine using Vanara.PInvoke.CldApi and found out that I am unable to invoke a copy hook handler (ICopyHook) from Vanara.PInvoke.Shell32 on folders that are being managed by a cloud provider.

As I am new to the Vanara project and also the CloudAPI, I might be doing something wrong but I followed the references from Microsoft and was able to register a copy hook handler. However, it does not get invoked at all so I searched for solutions and found IStorageProviderCopyHook. From what I read it seems that this is actually the intended method for invoking copy hook handlers on folders managed by a cloud provider.

I looked through all the libraries supported by Vanara and also did a git search but was unable to find anything related to IStorageProviderCopyHook. If it exists, I'd be grateful if someone could point me to it.

Describe the additions or enhancements you'd like
Would it be possible to add the IStorageProviderCopyHook interface to Vanara.PInvoke.Shell32 in order to be able to install a CopyHook handler for folders located under a cloud provider's sync root from the CloudAPI.

Previous work
I'm not aware of any previous work on this issue.

It is committed and will go out in the next release. While you wait, you can pull the current build from AppVeyor as described in README.md.

This is perfect, thank you very much for your quick reply.

@Blair88, have you been successful with the implementation? I tried to get the IStorageProviderCopyHook implementation to work, but the CopyCallback method isn't invoked for some reason, only a constructor and a destructor.

@dmitryshunkov IStorageProviderCopyHook only work on folders, renaming a file won't trigger the CopyCallback.
