what is codelens visual studio
Visual Studio 2013's new CodeLens feature provides a wide variety of information to the developer, all while never leaving the code editing window. Every once in a while, I come across a feature in Team Foundation Server or Visual Studio that almost seems like magic. I find at least one Oh, wow! moment with each release. The just-released Visual Studio 2013 does not look to be an exception to this rule: CodeLens is going to be that Oh, wow! feature.
