It's been a few years since dynamic .NET went mainstream with the promotion of the Dynamic Language Runtime into .NET 4, but it's still largely viewed as a fringe technology. This session aims to change that by reviewing what the DLR is, diving into how it works with C# 4 and Visual Basic 10, and looking at some interesting applications of dynamic typing in static languages. In particular we'll discuss C# interop with IronPython and IronRuby; simplified data access through micro-ORMs like Simple.Data and Massive; and static duck typing with ImpromptuInterface.
