At look at the Lync SDK with Marcelo Farjalla
Marcelo Farjalla is a program manager with Microsoft Lync. The Microsoft Lync 2010 SDK is a client API and set of UI controls that allows you to directly include communications in business process applications. You can embed UI controls and control conversations, extend the Lync conversation UI, conduct contextual conversations, and customize stand-alone applications. I asked Marcelo to tell us about the Lync API, what you can do with it, and show us a demo of his Communications Plug-in for Visual Studio sample application.
