Refactoring – Rename

Refactoring is a disciplined technique of restructuring your existing body of code by altering its internal structure without changing its external behavior.

The Rename refactoring is quite straightforward: it changes the name of a namespace, type, member, or parameter to something new. Rather than trying to make this sort of change using manual find/replace techniques, the Rename refactoring reliably renames all occurrences of the selected token throughout your entire project. You can preview the code changes before applying them to your code.
