@gep13 No. I haven't seen them before, but I haven't ported to net standard. I haven't ever attempted to run unit tests for my Xamarin projects through Cake. That's why I am so interested in what @mikegottlieb is doing. I am trying to learn from his problems so we can solve them. So I am going to try and reproduce the issues see if there is a good solution for them because I will face this at some point. Just not sure when.
