Use Microsoft Lync Controls to integrate Microsoft Lync 2010 features such as search, presence, instant messaging (IM) calls, and voice calls, into applications. You can drag and drop Lync Controls into existing business applications to add Microsoft Lync 2010 UI features and functionality. Use a single control or multiple controls.
Each Lync Control provides a specific Lync 2010 feature like search, presence, instant messaging (IM), and audio calls. The appearance of each control replicates the Lync 2010 UI for that feature.
The programming style is primarily XAML text, but you can also use any .NET language in the code-behind file to access Microsoft Lync 2010 SDK API and the .NET Framework.
