[1.1] Updated for Visual Studio 2017
This extension simply adds the equivalent to Sublime Text or IntellijIDEA's "Find in folder" and "Replace in folder" for Visual Studio. It's using the default Visual Studio Find and Replace dialog and automatically fill in the "Look in" targets for you.
It works not just on folder nodes, but also on project nodes and solution nodes (to Find/Replace in Projects/Solutions).
The extension is free and completely open-source @ https://github.com/nkahoang/VsFARMenu
