Looks like you have done a lot of good work!

I don't know about .Net, but in python-land there were three or four different oauth libraries floating around in various state of abandonedness. I guess they started out in the same way as you, by someone forking a project, working on it for a bit and then losing interest, whereby someone else comes along and creates yet another fork of the same project. For users (like me) that situation is very frustrating because there is no way you can choose the right oath project to use.

If I where you and I where serious about maintaining the project I would eradicate all impostors like a jealous God. Ensure that there are no download links to the old project, that it can't be NuGet:ed and that no other pages points to it. If people on Stack Overflow asks about .Net iCalendar, answer and recommend them your library. Add comments to answers pointing to the old library saying that it is abandoned and yours should be used instead.

It's a huge amount of work (see f.e https://github.com/search?utf8=%E2%9C%93&q=dday.ical) which is one of the reasons I don't like maintaining packages.
