Hello,
For some reason, my Unity (version 2019.2.5f1) won’t work with Visual Studio 2017 and 2019. I can create a new C# script and open and edit it, but when I go back to Unity I can’t connect my script to a GameObject. When I try, I get the error: “Can’t add script component ‘NewBehaviourScript’ because the script class cannot be found. Make sure that there are no compile errors and that the file name and class name match.”
When I click on the script I also get this prompt in the inspector: “No MonoBehaviour scripts in the file, or their names do not match the file name.”
This prompt is weird, because the format of the code in Visual Studio already inherited MonoBehaviour. I also read somewhere that this prompt will occur when the name of the class differs from the script name, but that is not the case. On top of that, I get a big error in the console when I create the script:
Win32Exception: ApplicationName=‘D:\Programma’s\Unity\Editors\2019.2.5f1\Editor\Data\Tools\RoslynScripts\unity_csc.bat’, CommandLine=‘/noconfig @ /UnityTempFile-20784131db4481b4d983963d59ba1aaf’, CurrentDirectory=‘’, Native error= the system cannot find the file specified.

What went wrong with my Unity? I redownloaded Unity a couple of times, even when I deleted all the Unity files on my pc that existed after the deletion of Unity. Other versions of Unity didn’t work either…
