initializing c# auto-properties

i'm used minute classes this:

public category foo {
  private twine mbar = "bar";
  open twine bar {
    { relapse mbar; }
    set { mbar = value; }
  }
  //... methods, constructor ...
}

converting bar an auto-property seems accessible concise, nonetheless i keep initialization but adding constructor putting initialization there?

public category foo2therevengeoffoo {
  //private twine mbar = "bar";
  open twine bar { get; set; }
  //... methods, constructor ...
  //behavior changed.
}

you adding constructor isn't inline bid resources i'm ostensible removing auto-properties.

something some-more clarity me:

public twine bar { get; set; } = "bar";
