Project Rider – A C# IDE
JetBrains is deadly. IntelliJ IDEA is simply the best tool I've ever used for HTML, CSS, JavaScript, PHP, and PostgreSQL. Incredibly intuitive and it does it all. It's what Photoshop is for designers.This immediately gets me stoked for doing my Unity C# development with this.* Edit. Initially thought this was an entirely new IDE, and not just a plugin. Less excited, but certainly worth a look.
