I have an Asp.net WebApi 2 site referencing .net 4.6.1. Up till now the site was referencing a PCL assembly (portable class library), for compatibility with UWP & Xamarin, without issues. Now I am trying to change that PCL to a NetStandard2.0 assembly, as recommended, but am receiving an error at site start up.
The error is below -
Method not found: 'System.Collections.ObjectModel.Collection`1 System.Web.Http.HttpConfiguration.get_MessageHandlers()'.
Any ideas? Thanks
