Lync Server 2010 SDK Documentation

Documentation updated Tuesday, May 22, 2012

The Microsoft Lync Server 2010 SDK download includes the SDK documentation, SDK library (ServerAgent.DLL), application development tools, and Microsoft Lync Server 2010 SIP Application API sample applications.

The Lync Server 2010 SDK documentation is a technical reference for the Lync Server 2010 SIP Application API that is used to create Session Initiation Protocol (SIP) server applications that customize and extend the functionality of Microsoft Lync Server 2010. It is intended for the following audiences:

  • Developers who want to use Application Manifests and Microsoft SIP Processing Language (MSPL) scripts to implement simple custom SIP message filtering and routing on computers in a Lync Server 2010 deployment.

  • Experienced SIP developers who want to create SIP-based managed code server applications that implement real-time content delivery or instant messaging infrastructure, including applications that work directly with SIP transaction objects or support multithreaded transactions.


The WMI-based Lync Server Management API is deprecated in the Lync Server 2010 release. The functionality is now supported by the Lync Server 2010 PowerShell Commandlets. For more information, see Registering a SIP Application with Office Communications Server and Managing a SIP Application on Lync Server.
