Framework Design Guidelines: Scenario Motored Framework Design
Ccontinuing in our hebdomadary blog post series that highlights a few of the newfangled additions to the Framework Design Guidelines 2nd edition.. This annotation is found in Chapter 2: Framework Design Fundamentals. Joe and Chris nail the core things.
