Welcome to the 100th episode of Going Deep ! It's been a great ride so far and I hope you've been enjoying the show over the years. For this momentous occasion, meet Bart de Smet , a software engineer extraordinaire on the WPF team who spends his free time blogging (what an incredible wealth of truly useful technical information to be found on Bart's blog !) and creating custom LINQ providers. In fact, Bart is probably the world's most prolific LINQ provider creator, from LINQ-to-MSI to LINQ-to-Simpsons! How does he do it???Of course, in this special episode who better to have involved in this LINQ'ified conversation (with lots of whiteboarding) than LINQ co-creator, programming languages designer, fundamentalist functional programming high priest and Channel 9 star Erik Meijer ? In fact, given that this is an Expert to Expert Going Deep, Erik co-conducts the interview (and he's great at it as usual!). Nothing better than watching and listening to two experts geeking out at a whiteboard!What makes LINQ so readily "providable"? How does Bart concoct his LINQ provider magic? Here, we dig into the details that enable LINQ-to-Anything.Tune in. There's a lot of very useful technical information here (which I hope is the case for all 100 Going Deep episodes).Enjoy and thanks for watching!
