.NET Enumeration allows comma in the last field

Question

Why is this .NET enumeration allowed to have a comma in the last field?
Does this have any special meaning?

[FlagsAttribute]
public enum DependencyProper         


        

Answer 1

Also (to Nick Craver post) its much easier to add new enumerations.

This behaviour appropriate not uniquely to enums. Consider following:

var list = new int[] { 1, 2, 3, };
