Question: Does anyone know if there is an extension or plugin for Visual Studio ( any version ) that will recognize Perl syntax highlighting? I want to edit the Perl files in my vs projects, but it gets hard to read sometimes. Thanks.

Answer: 
[Visual Studio Update 1 RTM](http://blogs.msdn.com/b/visualstudio/archive/2015/11/30/visual-studio-update-1-rtm.aspx) now (2015) has Perl support, along with Go, Java, R, Ruby, and Swift.
For Perl syntax highlight `ext install perl6`
