Upgrading a modern .NET (Core) version often means changing just versions in the project file. Upgrading from the old .NET Framework is bit more challenging, but we have also successfully upgraded a couple of Framework projects to modern .NET without too many issues.
Huh, maybe I misunderstood the nature of the .net work the guy I mentioned was doing. All I know directly is the pain of MSBuild itself. Thanks for the correction.
