Expression-bodied Members

Expression-bodied members are members whose bodies are an expression rather than a statement block. In many common situations, they make code more readable and compact.

The following listing shows a traditional method declaration:

public override string ToString()
{
 return "A textual representation of the object..";

public class Circle
{
    public int Radius { get; private set; }
    public Point Point { get; private set; }

    public double Area => Math.Pow(Radius, 2) * Math.PI;

    public double Perimiter => 2 * Math.PI * Radius;

    public Circle(Point point, int radius)

1. Consistent computer science naming. Map instead of Select. Reduce instead of Aggregate etc.
2. Does not throw exceptions unless something exceptional happens. Find (which is equivalent to Single) does not throw if no match is found.
3. People are more likely to search for "unique" than "distinct" etc.
4. Improves some methods like Range to take a step argument.
