Difference between Automatic Properties and public field in C# 3.0

Question

I failed to understand why auto implemented property language feature exist in C# 3.0.

What the difference it is making when you say

public string Fi         


        

Answer 1

The first is a public field, while the second is a public property.

The main difference is in how they are used. For example WPF can only data bind to properties, not fields.
