Expression bodies allow you to assign an expression to a method or getter property using the lambda arrow operator (=>), which you may be familiar with from fluent LINQ syntax. You no longer need to provide a full statement or method signature and body. This feature has also been improved in C# 7, so see the examples in the next section.
For example, a getter property can be implemented like so:
public static string Text => $"Today: {DateTime.Now:o}";
A method can be written in a similar way, such as the following example:
private byte[] GetBytes(string text) => Encoding.UTF8.GetBytes(text);
