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.

Install System.ServiceModel.Http package.

@cgountanis & @ctrl-brk,

I don’t use the .NetCore version as my daily driver (only created it to help the community and get my hands into NetCore). I’ll have to try upgrading my project and see if I run into the same issue or not. I’m also not sure what upgrading would do to all the people running on the version 1.1 framework and using my library. I’ll have to do some testing on this. Sorry I can’t be more help at the moment.
