Microsoft Lync 2013 SDK (Preview) is the client-side API set that enables the integration and extension of Lync experiences.

• Microsoft Lync 2013 SDK (Preview) includes Microsoft Lync 2013 API, a managed-code platform API that developers use to build applications that leverage the Microsoft Lync 2013 collaboration features. In addition to Lync 2013 API, Lync SDK includes a set of controls that can be used to add Lync features to a Microsoft Windows Presentation Foundation (WPF), or Microsoft Silverlight 4.0 application.
  
  With Lync SDK, you can add Lync 2013 features to an existing business application, or create a custom client that includes Lync 2013 features. In either case, Lync 2013 must be a running process on the client computer that hosts a Lync 2013 API application.
  
  To add Lync 2013 features to an application, use a drag-and-drop operation to move XAML controls from Lync SDK into a WPF or Silverlight application. For more advanced scenarios, use a .NET Framework language to incorporate Lync 2013 API features into your application.
  
  Lync 2013 API is commonly used to start a new conversation within your custom application, after which you will participate in that conversation using the Lync 2013 conversation window. You can also start and participate in a conversation within your custom application without displaying the Lync 2013 conversation window. Lync 2013 API can also be used to generate a contact list within your custom application using data obtained from Lync 2013.
