c# - Omitted setter vs private setter?

Question

What is the difference between a property with a omitted setter and a property with a private setter?

public string Foo { get; private set; }

vs

public string Foo { get; }

Answer 1

In C# 6, get; only properties are only settable from the constructor. From everywhere else, it is read-only.

A property with a private set; can be set from everywhere inside that class.
