I have a UCMA 4.0 program, handles IM calls supports Application Sharing. It always worked fine for me on Lync 2013 conversations.
Recently I upgraded my program to UCMA 5.0, using Skype for Business instead of Lync 2013.
Strangely, since I did, Application Sharing doesn't work for me anymore.
The moment I confirm the Desktop Sharing action – I get this error:
"Screen presenting isn't supported with this contact." , at the bottom of the conversation window.
My code is :
endpoint.RegisterForIncomingCall<ApplicationSharingCall>(ApplicationSharingCall_Received);
Good scenario is: once I confirm the Desktop Sharing action - ApplicationSharingCall_Received event is raised.
Trying to debug it, I realized that no matter what I do, the breakpoint on this event is never hitted, in contrast to the old version.
It seems like I miss some changes between Lync 2013 to SFB version.
Is there any other event I've never heared about?
Does anyone have any other suggestion for me?
