How to make Unity open Visual Studio 2017 to edit code

manpreet Best Answer 2 years ago

Basically every time i try to open a c# file from unity i get:

message "one or more projects in the solution were not loaded correctly. please see the output window for details"

followed by "An exception has been encountered. This may be casued by an extension. you can get more information by examining the file ..." This file is really long so I will paste the errors only:

I uninstalled VS enterprise and installed VS community. I was then able to open VS via unity to edit code. I wondered why it should make a difference between VS enterprise and community, so I uninstalled community and reinstalled enterprise. And .... it worked. So to recap: Uninstalling and reinstalling Visual Studio fixed my issue.
