In Visual Studio, I have added an OpenAPI service reference to my .NET project, so that I can use it as a client for that service.

So far all is well, but now something has changed in the service definition, and I need to re-import the OpenAPI file. From the Connected Services window, I tried the Refresh service references button (and also … > Refresh, which I think does the same)

The OpenAPIs\swagger.json file is not updated, and also the generated C# code does not change.

Is it possible to refresh a service reference, or do I have to remove the existing one and recreate it from scratch?
