We developers often take IDEs for granted. But have you ever wondered what’s going on under the surface? I’d like to pull back the curtains on the inner workings of the modern IDE, see where the state of the art is now, and look where it’s heading for the future. We’ll take a tour of the wealth of features provided, and take a deep dive into how the IDE knows so much about your code, and how it can provide such fast navigation and safe refactorings. We’ll also look at why some people are choosing to move away from IDEs and back to text editors, and what the future holds, with projects such as Nitra, Roslyn and Lighttable.
