What is the fine-grained topic of the following text: The new C# features I discussed were Optional and Named Parameters and Dynamically Typed Objects – of course no discussion of Dynamically Typed Objects would be complete without mentioning the Dynamic Language Runtime and I also talked about ExpandoObject and DynamicObject and how both C# and VB can use this new dynamic capability. Only return the topic.
