• Adding ObsoleteAttribute to (or otherwise greylisting) Types not under my control?

  - by Michael Stum

  Is there a way to somehow mark Types I do not control as Obsolete? Basically I would like to add ObsoleteAttribute to types I do not want to use in my .net Project (i.e., SerializableAttribute) I believe I can do something like that with FxCop, but ideally I would like to have the compiler already generate warnings for "greylisted" Types? This should be on a Per-Project level, but sadly "Extension Attributes" don't exist, and adding them at Runtime is too late for ObsoleteAttribute...

Is this something that must be handled manually in code, or is it somehow implicit and I'm not recognizing it, maybe through helper methods or classes? I want to apply it to math operations to ensure 3 + 5 * 10 results in 53 instead of 80.
