I went through and referenced other versions of WRobot' s wManager and found Wrath was good, Cata, MoP, WoD, and Legion were all red. The error I'm getting is "cannot resolve symbol". I changed .net versions but that didn't help either. I even tried every suggestion online to possibly correct it. But it does compile for me. It's odd.
I get the error using DistanceTo with WowPlayer and WowUnit. Basically anytime DistanceTo is used.
