Visual Studio comes with great out-of-the-box refactoring functionalities such as renaming and the creating method from a selected piece of code.

The renaming functionality can really help with potential errors in code, such as when changing the name of an element. There might be instances in the codebase where the old name is still used. Let's have a look at the following code:
