To be fair, this is also how VS looks when you open a project fresh from the clone. Or after updating .net versions. .NET is awful about losing references and then claiming thousands of errors. Sometimes just running the build will fix it by relinking the DLLs it couldn’t find.
But also yes, VS with a team can be “fun” if people don’t sync their formatting settings. I once had a junior that kept converting spaces to tabs on every file he’d touch. You’d get it fixed and then he’d screw up his settings again with a VS update or something.
