Remarks

Assigns a unique long ID (starting at 1) to each distinct object reference presented to it.

This is a drop-in replacement for System.Runtime.Serialization.ObjectIDGenerator, which Microsoft marked obsolete in .NET 8 (SYSLIB0050, "Formatter-based serialization is obsolete and should not be used"). The observable behaviour is the same: IDs are assigned sequentially starting at 1, objects are compared by reference identity, and GetId reports whether the object had been seen before.
