Hi, I have a problem, I have a solution with two projects, one web and a shared project Xamarin. What happens is that it is as if the xamarin project had been "broken", as you can see in the image it is all underlined in red, in all it says, "There is no directive using or reference to a message". The web project that is in the same solution works well. I open another project that had test of shared project xamarin and the same thing happens. Another strange thing that happens is that I run it runs well, and if I compile it does not give errors. Thank you PS: and restart the visual, the PC, etc.
