This repository was created for the Productive Dev YouTube series on refactoring legacy code (here's the link).
- Improving testability
- Inversion of control via dependency injection
- Message-sending between objects
- Making smaller things
- Improving naming
- Extracting configuration
- Programming to abstractions instead of implementations
- Replacing conditional logic with polymorphism

Task.FromResultfor non-asynchronous overiddes ofTaskmethods - Writing unit and integration tests
