Remarks
.NET Framework only: Set this property to true for a Socket you intend to call DuplicateAndClose on. Otherwise, the Framework may assign a completion port to the socket, which would prohibit the use of DuplicateAndClose.
On .NET 5+ (include .NET Core) versions, the value of this property is always false, and you cannot change its value.
