How to update the generated AutoRest code after changing the REST server API?

Question

Context

I am writing client code to access the REST web API service. I use typed client classes using Visual Studio 2015 "Add" / "Client REST API ..."

Now the serveride API has changed, and I would like to update the generated client code accordingly.

Question

Besides the obvious solution to remove all generated classes, then starting with Visual Studio 2015 “Add” / “REST API Client ...” from scratch, is there a better way to do this?
