Why this name ? As someone who has family in this town I'm wondering. Historical reasons ? Some character in a game I don't know about ? Random chosen french city ?
Back when this was an internal MS project (and I was working there, on another team), I believe the icon for the Orleans (internal) nugets and the demo apps was the Mardi Gras flag, which suggests that it's named after New Orleans. I might be misremembering.
French? Orleans is right down the street here in Massachusetts. ;)
Still, the name makes searching for help and information difficult.
