Hi, can you please help? I started the Complete Unity 2 D developer course about two months ago. The issue appeared straight away, i loaded my first script and i am getting multiple Onmisharp failure messages. I followed the installation procedure as per the course, but no luck. I then downloaded Unity onto my laptop and i am getting exactly the same error messages. I have downloaded the support .net packages as advised. I have scoured the internet for answers and watched countless video’s on Youtube, but i cannot resolve this. Am i missing something really simple? I have been through the error messages and i am truly stuck. Can some please help, as i am about to through the towel in. Please find below the fail messages .Thank you in advance
