The .NET Rocks team does a great job discussing hot technology topics. While at the Tampa Bay Florida stop of the .NET Rocks! Visual Studio 2012 Launch Road Trip, Carl Franklin and Richard Campbell talked to me about building Single Page Applications (SPAs). You can listen to the interview online here or download the interview from this link. We discussed what a SPA is, the many technologies you can use to build one, when to build one, and took several questions and comments form the live audience.
