Build fails with the errors listed the dotted lines, but only a summary, since there are lots of related errors.
Updating the Nuget reference to Microsoft.AspNet.WebApi from the installed version of 5.2.2 to 5.2.3 solves the issue.
The following frameworks are updated, all from 5.2.2 to 5.2.3
Microsoft.AspNet.WebApi
Microsoft.AspNet.WebApi.Client
Microsoft.AspNet.WebApi.Core
Microsoft.AspNet.WebApi.WebHost
