MvcReportViewer: System.ServiceModel.Http not found with dotnetcore 2.0

After upgrading my project from 1.1 to core 2.0 getting the following error when serving under IIS. Never had this in 1.1.

System.IO.FileNotFoundException: Could not load file or assembly 'System.ServiceModel.Http, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.
