I've completed Milestone 3, completing a Milestone early for the first time in quite a while. There was a bit of an issue with needing to store multiple types in a List instead of an IEnumerable, and I also had an issue with LINQ queries having strange return types, but those are both fixed now. I'm not 100% sure about the responsive design stuff, but I still think it might just be some sort of problem with my machine? I think I've followed directions in terms of how to do the stuff with the flex columns reasonable well, so hopefully, it works for the TA testing it.
