Assembly: Microsoft.Lync.Controls (in Microsoft.Lync.Controls.dll)
This control provides an result list for a contact search. To initiate a search, this control must be paired with a ContactSearchInputBox.
The ContactSearchInputBox and controls, while related, are designed as separate controls to allow the developer to display search results and search input in separate locations on a page.
Alternatively, use the ContactSearch control, which encapsulates both features in a single, self contained control.
