What You Should Know Now — and What's Next

What You Should Know Now

• Core syntax: variables, properties, control flow, arrays, methods
• Object-oriented programming: inheritance, polymorphism, interfaces, and encapsulation via properties
• Collections, generics, delegates/events, and LINQ
• Nullable reference types, records, and pattern matching
• Exception handling, file I/O, and async/await
• Multithreading with the Task Parallel Library, reflection, and dependency injection
• Building a web API with ASP.NET Core and Entity Framework Core
• How a production C# service is tested, packaged, and deployed

What Should You Learn Next?

• ASP.NET Core in depth — middleware, authentication, and Entity Framework Core migrations, building directly on the Web API lesson above.
• A related language — Java, a close sibling with a very similar type system, OOP model, and managed runtime, if working across the JVM ecosystem interests you.
• Unity — if game development interests you, the same C# knowledge from this course transfers directly, on top of Unity's own APIs.
• .NET MAUI or Blazor — if you'd rather build a UI (mobile/desktop or web) than a backend service next.

Build Something

Pick a project idea that solves an actual problem you personally have — and build it as a small ASP.NET Core service backed by a real database, with an xUnit test suite alongside it from the start.
