You're assuming a workshop where there's just one significant app. The last several places I've worked there were dozens of apps, microservices, and APIs; some of the old and stable APIs were .NET Framework and those never needed to be touched. We built all of the new hotness using .NET Core, Blazor, and whatever the JS framework de jour was, all without needing to touch the old, stable, and working Framework code happly humming along in its VM.
