Abstract

The chapter delves into the C# dynamic keyword, which allows for loose typing in an otherwise strongly typed language. It explains how dynamic data is processed by the Dynamic Language Runtime (DLR) to enable late-bound method calls and simplify COM interoperability. The author provides practical examples and discusses the trade-offs between using dynamic data and maintaining type safety. The chapter also covers the role of expression trees in the DLR and how they facilitate the mapping of dynamic calls to in-memory objects.
