Deep Dive into OWIN Katana


I was asked to give a presentation about OWIN and Web API to a different development team, as they wanted an introduction to the technology and no one in the team had exposure to that technology before.

All these resources are derived from the same object called Resource, which comprises properties such as Id, Meta (contains VersionId and Profile). The derived classes may have their own specialization properties/fields.
