Answer
Action represents methods that return void, while Func represents methods that return a value.
They reduce the need for custom delegate declarations and simplify modern C# programming.
Quick Answer
Action is a built-in delegate for methods that return void. Func is for methods that return a value — the last type parameter is the return type. They eliminate the need to define custom delegate types for most scenarios and work seamlessly with lambdas and LINQ.
