problem so I had this issue for a couple of years where sometimes when I create a file in the visual studio everything turns to errors even though I haven't touched anything. as shown by this picture
my computer its a MacBook Pro with macOS 10.13.6. visual studio 7.7.4
fixes to fix the problem I would normally restart vs like 5-6 times and i would come right but it has now stopped working completely. i noticed that there are a lot of people complaining on other websites about this problem from 2012 and they have fixed it by removing the .sdf file, removing the .suo file, updating Xamarin Studio & updating the android sdk, using an older version of .net, clearing their ReSharper caches and unloading and reloading their project. (and yes I have restarted my computer) however non of this works for me so I'm kinda stuck.
I was wondering if anyone has the same problem or a fix I could try.
