If you know C# and the basics of object-oriented programming (OOP), but your classes keep growing, your if/else chains keep multiplying, and every new feature means editing five files, SOLID is the missing piece. The course SOLID Principles in C#: OO Design for .NET Developers! teaches all five SOLID principles — SRP, OCP, LSP, ISP and DIP — and applies them to a single real-world example so you can see bad design turn into clean, maintainable, testable code.
Who is this for?
Ideal for C# developers who know OOP basics and want to write better-designed code. Also, .NET developers preparing for interviews, where SOLID principles come up constantly, can benefit from this course.
Software Required
This is a concise, focused course: under an hour of content, with no filler. It's deliberately concept-first — the emphasis is on the design reasoning behind each principle rather than IDE walkthroughs, so what you learn applies whether you work in Visual Studio, Rider or VS Code.
