This question keeps coming up a lot onStack Overflow for some reason:What was Stack Overflow built with? Some evenwondered if Stack Overflow was built in Ruby on Rails. I consider that a compliment! This question has been covered in some detail in ourpodcasts, of course, but I know not everyone has time to listen to a bunch of audio footage to find the answer to their question. So, in that spirit,here's the technology "stack" of Stack Overflow, the stuffJarrod, Geoff, and I used to build it: frameworkMicrosoft ASP.NET languageC# development environmentVisual Studio web frameworkASP.NET MVC browser frameworkjQuery databaseSQL Server 2008 data access layerLINQ to SQL source controlSubversion (nowMercurial through Kiln) compare toolBeyond Compare source control integrationVisualSVN (now,VisualHg) We have a few other minor dependencies as well, such asReCaptcha,DotNetOpenId, and theWMD control (which we subsequentlyrewrote), but that's about it.
