Hi Christopher,

By employing the C# migration tools, you'll be able to save a lot of time in the implementation of the API. Mainly because it will convert the PB code to C# and scaffold the services and controllers automatically. If done correctly, you'll be later able to replace the data layer with EF Core just by reimplementing the data services' interfaces in terms of EF and injecting them at the application startup.

Edit: of course how easily this can be accomplished will depend on how well abstracted your application is. That is, the UI code should not be mixed with the business logic code you want to migrate.

Hope this helps.

Regards,
Francisco
