I need to integrate Lync Conversation Window Extension(CWE) with Skype for business(s4b) for some project requirement. Is CWE compatible with s4b? if yes how feasible it is to implement it. On official documentation - https://docs.microsoft.com/en-us/lync/desktop/how-to-create-a-conversation-window-extension-application-in-lync-sdk of for Lync CWE, there were three prerequisites for this development - 1. Microsoft Lync 2013 must be installed and running on the development computer. 2. You must have sign-in credentials for Microsoft Lync Server 2013. 3. Microsoft Lync 2013 SDK must be installed on the development computer.
So that is why I have doubt whether it is compatible with s4b or not.
