You need to use ContentBySearchWebPart class which is present in Microsoft.Office.Server.Search.WebControls namespace and Microsoft.Office.Server.Search dll.

  • ContentBySearchWebPart Doesnt exist in this namespace !

  • Added these things using Microsoft.Office.Server; using Microsoft.Office.Server.Search; using Microsoft.Office.Server.WebControls; But still cannot find ContentBySearchWebPart

  • See my updated answer. The dll should be Microsoft.Office.Server.Search. You can find it here: C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.Office.Server.Search.dll Nov 13, 2014 at 10:19
  • You should add a reference to Microsoft.Office.Server.Search.dll assembly, then using Microsoft.Office.Server.Search.WebControls; (see msdn.microsoft.com/en-us/library/…)
