Carl and Richard talk to Mads Torgersen about his work on C# and Roslyn. Mads talks about how old the Roslyn CTP has gotten - and how that may change in the future. There's also a hint about a form of Roslyn already seen in the wild (hint - it's CodeLens!). And the conversation gets crazier from there, but it comes down to one thing... is C# in Roslyn, or is Roslyn C#? Have a listen!
