It significantly cuts down on time and reduces the margin of error by the way in which it handles changes in the code and automated operations. 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:

class foo:
    """
    Documentation of the class.
    It can be multiline and contain any amount of text
