C# 7 Expression Bodied Constructors
A way to do this is to use a tuple and a deconstruction to allow multiple assignments in one expression:
public class Person
{
public string Name { get; }
public int Age { get; }
public Person(string name, int age) => (Name, Age) = (name, age);
}
As of C# 7.1 (introduced with Visual Studio 2017 Update 3), the compiler code will now optimise away the actual construction and deconstruction of the tuple. So this approach has no performance overhead when compared with "longhand" assignment.
