These are my links about the new C# 5, its history, and the main two new features: compiler as a service, async/wait asynchronous programming. Related post: Windows 8 and WinRT: Links, News and Resources.
Future directions for C# and Visual Basic
Anders will talk about asynchronous programming and Windows 8 programming, coming in the next version of Visual Studio. He will also discuss the long-lead project “Roslyn”, including object models for code generation, analysis, and refactoring, and upcoming support for scripting and interactive use of C# and Visual Basic.
