In this episode we get the pleasure of picking the brain of the lead designer of C#, Mads Torgersen. Mads has been the lead designer for more than five years now and has worked on the language for over fifteen years. Our discussion covers multiple topics including the growth of C#, being backward compatible and how different languages incorporate ideas from each other. We also dig into the specifics of things like async/await, default interfaces and dynamics. On top of all that we get a peek at the future of C# and what we might see in the next couple of versions. What would you ask Mads about C# if you had the chance? Let us know on Twitter at @dotnet_Podcast.
