Yesterday I gave a talk to the Redmond .NET user group where I talked about the C# 4.0 dynamic feature. The talk focused on how the feature is implemented and how all the pieces go together.
About 30 people showed up and stayed for the 1 hour and 40 minutes of dynamic talk.
According to the feedback I got, people enjoyed the technical talk, and that made me feel good [:d].
I have attached the slide deck if you are interested.
