Visual Studio is twenty years old! Carl and Richard chat with Julia Liuson, who has been involved with Visual Studio since its very earliest days in the 90s. Julia talks about how Microsoft decided to build a unified IDE for all its various development products including Visual Basic, C++, FoxPro and their new web development tool, Visual InterDev. But following quickly on from the 1997 edition was .NET and the complete change that it created for Visual Studio. Lots of great stories from someone that has been involved since the beginning - here's to another twenty years of Visual Studio!
