Writing IDE Code Fixes, Refactorings, and Intellisense Completion Providers

In this chapter, we will cover the following recipes:

• Creating, debugging, and executing a CodeFixProvider to fix a compiler warning
• Applying batch code fixes (FixAll) across different scopes: document, project, and solution
• Creating a custom FixAllProvider to fix all occurrences of an issue across a scope
• Creating a CodeRefactoringProvider to refactor source code to recommend using C# 7.0 tuples
• Creating a CompletionProvider to provide additional intellisense items while editing code
• Writing unit tests for a CodeFixProvider
