About a month ago, Ed Pinto and I did an interview with the .NET Rocks guys on What is new in WCF for .NET 4 and it just went live today. Ed covered most of the detailed technical stuff, I filled in more along the value proposition side of things, and Carl and Richard added their usual comic relief and excellent interviewing skills. It was fun. Hope you enjoy!
