CodeLens. Visual Studio 2013's new CodeLens (Code Information Indicators) feature is shown above a method and lets developers quickly view all references of that method within their code. In addition, CodeLens is useful for determining how many tests are referencing a method and how many of those tests are passing. CodeLens also keeps track of who last checked in a change or modified a method.
Peek Definition. Going beyond Visual Studio's Go To Definition feature, Visual Studio 2013 introduces the Peek Definition feature that lets developers peek at the declaration inline -- without having to leave their place within the code.
Enhanced Scroll Bar. Microsoft has also enhanced the scrollbar in the editor that shows useful information at a glance. For example, you can see where edits in the file are currently pending or where the last save to the file made changes.
