Visual Studio + ReSharper is a dream come true. As someone who learns by doing rather than studying, ReSharper's refactorings and inline code reformatting suggestions was an invaluable source of idiomatic C# knowledge (second only to great code reviews from one of my C#-clueful coworkers). And Visual Studio's debugger lets you move the program counter backwards, which is just awesome for interactive REPL-esque development. (No, I'm not a JetBrains employee -- just an avid fan of every product of theirs that I've used.)
