Extract local function refactoring

This refactoring applies to:

• C#

What: Lets you turn a fragment of code from an existing method into a local function.

When: You have a fragment of existing code in some method that needs to be called from a local function.

Why: You could copy/paste that code, but that would lead to duplication. A better solution is to refactor that fragment into its own local function.

How-to

1. Highlight the code to be extracted.

2. Press Ctrl+. to trigger the Quick Actions and Refactorings menu.

3. Select Extract local function.
