Introduction

This article helps you if you’re already familiar with C# and LINQ and you need to:

1. Prepare for interviews, or
2. Reacquaint yourself with the language after a period away from C# e.g. moving from frontend development in Angular and TypeScript to a backend project.

Each part consists of a “drill” that explores important operations of a few common linq operations.

Names of variables and methods are kept deliberately short to minimize the amount of typing required to complete the code exercises.
