Dominick Baier returns to talk to Carl and Richard about the current state of security in .NET 4.5. Dom starts out talking about how WebAPI has impacted the development of web services without much in the way of new security features - so he built some for everyone to use (check the links below). The conversation then digs into the challenges around OAuth 2 and the challenges of building specifications by committee when you're dealing with security. Also listen for a great dig into the real goals of identity technologies that largely haven't come to pass yet - there's still a ways to go!
