What's the difference between using

public string Username { get; set; }

and using

public string Username;

I have always been using the first one, but wanted to understand if there is any difference between the two, and scenarios when one should prefer over the other.

Answer 1

public string Username { get; set; }

• is a Property.

while

public string Username;

• is a Public variable.

For more comparison,

• Reflection works differently on variables vs. properties, so if you rely on reflection, it's easier to use all properties.
• You can't databind against a variable.
• Changing a variable to a property is a breaking change.
