Roslyn is out - and it's awesome! Carl and Richard talk to Dustin Campbell about his work building Roslyn over eight years. Eight years is an awful long time, but when you're rebuilding a codebase from scratch, it's hardly unprecedented. Dustin talks about some the decisions made in the re-engineering of C#, including whether or not to keep in the bugs! Taking Roslyn open source is also a huge aspect of Roslyn and it's impact on the rest of the open source products Microsoft is making including the new ASP.NET. Great insight from someone who's been there!
