Next Steps

What you can do now

• Install the SDK and run console apps
• Use types, strings, arrays, lists, and control flow
• Build classes with properties, inheritance, and interfaces
• Apply LINQ, async basics, and nullability warnings

Practice ideas

Build a console quiz that stores questions in a list, scores answers, and saves results to a text file with try/catch.

Common traps

• Ignoring nullable warnings
• Blocking on async tasks with .Result
• Giant classes that mix UI, logic, and storage
• Catching Exception everywhere and swallowing errors

Where to go next

• ASP.NET Core for web APIs
• Entity Framework Core for databases
• xUnit for automated tests
• Records, pattern matching, and spans
• Dependency injection concepts in .NET
