@drewnoakes @genlu we have had bunch of reports of this duplicate entries issue now..

Hitting this issue now adding the analyser to the winforms repo, pretty annoying.

Also still having this issue. Note that at least in my experience, it not only adds an entry for the class for each part, but also if there's no explicit constructor it also adds a constructor entry for each type part found.

Any traction on this at all? It's been a year since this issue was posted and still no resolution, even with the Urgency-Soon tag.
