New Article by Bill Wagner on Dynamic Method Bags in C# 4.0

C# MVP and wunderkind Bill Wagner has written an article entitled Dynamic Method Bags which is now available on MSDN. Bill explores the new dynamic feature in C# 4.0. Most posts on this subject explain how to use dynamic to call Python, Ruby or Office. In his article, Bill explains how dynamic can be used not to call another language or tool, but to call your own C# objects without directly using the reflection API’s. The solution he provides combines generics, expression tress and dynamic to create a “type that allows developers to add new methods at runtime” and call those methods through dynamic dispatch.
