About this course
The journey
C# has changed a lot in recent versions, and code written the old way is longer and easier to break. This course shows the modern features side by side with the code they replace: records, init-only properties, switch expressions, list patterns, nullable reference types and primary constructors.
Each lesson refactors a real piece of legacy-style code, so you learn when a feature helps and when it does not.

Rated 5.0 out of 5Refactoring legacy code, step by step
Seeing old-style code turned into switch expressions and records side by side convinced my whole team to update our style guide.
