Trailling commas in object/list initializers and enums in C #

[vsfeedback]

This issue has been moved from a ticket on Developer Community.

It would be nice if IDE could be set up to remind to add trailing commas to object and list initializers and enums (and wherever else possible), so that subsequent changes that would add items to the existing lists wouldn't have to touch the existing lines making diffs cleaner.

I.e. for a code like:

enum Something
{
    One,
    Two
}

it would be nice to have an optional suggestion to add a comma after Two. So that when a Three is added to a list, the diff would highlight only one line (since the line with Two would not be touched).

Is this a dup of #25206 or does IDE support require explicit implementation besides .editorconfig support?

[jmarolf]

it should not. I think this is a dupe
