I held a short presentation about some of the new features in .NET 4.0 at Norwegian .NET User Group last Thursday. I talked a bit about the dynamic keyword and had a very short look at Code Contracts. Joar held a short talk about new features in Visual Studio 2010. Before Joar and I talked, Tore Vestues held a very good talk about the programming language Boo. I was inspired by his talk, so I will for sure have a look at this language soon.
This is cut from the Boo web page:
"Boo is a new object oriented statically typed programming language for the Common Language Infrastructure with a python inspired syntax and a special focus on language and compiler extensibility."
You can find the slides from my talk below.
