Pattern matching has grown far beyond switch and case statements. From type checks to recursive patterns and list matching, modern C# gives you expressive tools to write cleaner, more maintainable code.
Exception filters make error handling in C# cleaner and more expressive. They let you catch only what you care about without cluttering your code with nested logic or rethrows.
Null reference exceptions are one of the most common runtime errors in C#. Nullable reference types let the compiler help you avoid them—if you use them correctly.
