title: Enum deprecated c#
body: <p>I have a deprecated (Obsolete) function which returns an enum, and I have a new function which returns a List of enums.</p>
  
  <p>One of the <em>enum values</em> is used only in the deprecated function, so is it possible to set an <em>enum member</em> as obsolete (because it can't be in the List)?</p>
