This is going to break any Xamarin dev using Fody very soon. It looks unfortunately like this project is a bit dead. I took a quick look at merging in the upstream Cecil changes back into Fody’s fork, and it looks like maybe Cecil now includes the functionality Fody had added to their fork, so perhaps it’s possible to use Cecil as a true dependency. I may have an extended look at this over the next few days.
