8.0.100, 8.0.405 and 9.0.203. I am on Arch Linux but installed these through the install script from microsoft. As for EF Tools I'm using version 9.0.0 but have also tried 9.0.2 and 9.0.4, neither worked and the same error is returned each time. I have tried running the command with --msbuildprojectextensionspath and it yielded the same result. I'm getting kind of hopeless, I've never before experienced this kind of error and migrations have worked just fine in other projects. Any help is greatly appreciated.
