Tfl.Api.Presentation.Entities missing a dependency



As a newbie to using the Unified API with .Net, I downloaded the DTO zip file from the page’s API response types link and extracted it. It contained 1 assembly: Tfl.Api.Presentation.Entities, version When I try to reference types, e.g. StopPoint at runtime, an exception is thrown, as a dependency of Tfl.Api.Presentation.Entities is missing. Exception details are:
‘Could not load file or assembly ‘Tfl.Api.Common, Version=, Culture=neutral, PublicKeyToken=null’ or one of its dependencies. The system cannot find the file specified.’
Am I missing something here, or do I need to get this dependency from somewhere else?
