Lync 2010 Controls Architecture Overview
This topic introduces the Microsoft Lync 2010 Control architecture in which a Lync 2010 Control application connects to Microsoft Lync Server 2010 by using a single out-of-process connection to Microsoft Lync 2010. The application is either a Microsoft Windows Presentation Foundation (WPF) or Microsoft Silverlight application that contains Lync 2010 Controls.
The application’s connection to Lync 2010 is created by the first Lync 2010 Control that is instantiated by the application. This first control configures the layer between Lync 2010 and the application. The initial Lync Control automatically performs the following tasks.
Adds Lync 2010 connectivity to a WPF or Silverlight application without requiring code-behind.
Allows use of multiple interfaces between Lync Controls and Lync 2010 in a single application.
Handles and exposes run-time errors.
Ensures shut down of the layer between the Lync Controls application and Lync 2010.

Each successive Lync Control that is opened by the application uses the existing connection. To get the connection state, check the following properties.
IsSignedIn property
InitializationError property
IsInResiliencyMode property
InitializationErrorMessage property
