Using tools like GitHub Actions or Azure DevOps to build and test your C# solution every time code is pushed.
Depend on abstractions, not concretions. Use Dependency Injection (DI) —built into .NET Core—to decouple your classes. 2. Essential Design Patterns in C#
To implement using C# , you must bridge the gap between abstract values (like those in the Agile Manifesto) and concrete technical execution. In a C# environment, this is primarily achieved through SOLID principles, Design Patterns , and Extreme Programming (XP) practices. 1. The Core Principles (SOLID)
Defines a family of algorithms. In C#, this is often implemented by passing different interface implementations (e.g., IPaymentStrategy ) into a service at runtime.
Abstracts data access. It allows you to swap a SQL Server implementation for a Mock version during unit testing, facilitating Test-Driven Development (TDD) .
Subtypes must be substitutable for their base types. This ensures that inheritance in C# doesn’t break your logic.
