.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

I know that it is an old topic but, another approach that would make sense for this issue is for code versioning systems.

Consider the following example:

//version 1
var myArray = {
    "item 1",
    "item 2"
};
//version 2
var myArray = {
    "item 1",
    "item 2", //will be considered a change, it may be considered an erroneous approach
    "item 3"
}

Now consider this approach:

//version 1
var myArray = {
    "item 1",
    "item 2",
};
//version 2
var myArray = {
    "item 1",
    "item 2", //will not be considered a change, it may be considered an erroneous approach too, but, means that the code wasn't changed intrinsically
    "item 3",
};

Anyhow, both approaches may be considered incorrect or correct depending on the situation. I particularly prefer the second approach that makes much more sense when dealing with code versioning systems.

Anyway hope this helps.
