Stuart describes each major feature and why it is useful. But doesn't get into best practices nor suggested usages. Just the facts about each feature.

Whirlwinds are bite-sized webcasts, generally shorter than 15 minutes. You can start anywhere in the series to learn about the parts you're most interested in.

Stuart describes covariance and contravariance. These features provide way for you to access collections of derived classes and base classes.
