title: TFS 2015 "delta" for build definition
body: <p>I'm trying to find solution for TFS 2015 to build "delta" for my build.
  In TFS 2013 it was done by "Clean Workspace" setting with parameter "Output".</p>
  
  <p>Outputs: to delete all existing outputs but get only those source files that have changed since the last build (Incremental Get);</p>
  
  <p>Could someone tell me please how this should be done in TFS 2015?</p>
  
  <p>Thank you.</p>
