I also read that page as if it should throw if called before 'MoveNext' were called. The documentation is unclear as to what exception this should throw.

Then you can build on .net 3.5, but you provide the needed libraries for ppl with only .net 2.0 timm, you can include the System.Core dll in your own .net 2.0 install, see comment #12 on the page you gave a link for.

Unless you need to instrument the enumerator, wouldn’t

private static readonly T[] empty = new T[];

and

return empty.GetEnumerator();

be a simpler approach?
