I'm trying to log the file name when attaching the file in skype for business by using Lync Client SDK 2013. I used the ContentSharingModality's ModalityStateChanged and ContentAdded event.
My problem is that this ContentSharingModality's event only raised successfully on a online meeting but this cannot raised when normal IM,Audio/Video Call. Could you advice the best solve of my problem?
Thank you.
