CWE overview

Microsoft Lync 2013 CWE is an embedded browser that allows display of a contextual application with a Lync 2013 conversation. CWE provides a hosting environment that supports traditional and rich Internet applications. To display a Microsoft Silverlight application in CWE, embed the application in an HTML page. For more information, see How to: Create a Conversation Window Extension application in Lync SDK.

Opening Conversation Window Extension

CWE opens programmatically in the following scenarios:

• When a registered context package opens in a conversation. For more information, see Register contextual conversation packages.

• Use the BeginOpenExtensibilityWindow method.

CWE can also be opened manually by selecting an application from the contact card Options menu. For more information, see Add custom commands to Lync menus.

Closing Conversation Window Extension

To close CWE, click the Close button on the tab at the bottom of the window or use the CloseExtensibilityWindow method to close the window programatically. Otherwise, CWE closes when the conversation window closes.

Conversation Window Extension size

There are two ways to specify CWE dimensions:

• Use the ConversationWindowExtensionSize enumeration.

• During Install Registration, use the ExtensibilityWindowSize registry key for the CWE application. For more information, see Register contextual conversation packages.
