Question [Solved] 'ToolManager' does not exist in the current context

I'm getting this error, plus 6 more related to it, and it's preventing me from compiling.



I got the error when I synced my project with my partner's changes via Collaborate. The only suspicious changes that could have cause the problem were these.


I've tried updating my packages, and I also made sure that I had all the same packages as him, and that they were the same versions.
Any help is greatly appreciated.

 

One approach is to force remove all packages, let Unity consider that (57,000 compiler errors), close Unity, open afresh, then restore package changes. This is trivial with git source control but I don't know how Collaborate works.

 

Thanks for the recommendation. Turns out my partner and I had different project versions. He wasn't aware that he updated Unity, but somehow he got a newer version. I switched over to that version and all the errors are gone.
