I tried the following combinations:

Existing API Center, new portal - Works great!

New API Center, new portal - Works great!

Enhancement: It would be nice to not have to provide the API Center location for the existing API Center scenario (can it be determined from the API Center service name and resource group name?).

There are a few other things that need to be cleaned up before I can merge. Our documentation on Microsoft Learn assumes you are using config.json, and the local debug scenario also assumes config.json is the file name. Can you submit a PR to clean up the Learn documentation as well?

Other than the impact of renaming config.json to config.example, the AZD portions of this PR LGTM!

@pierceboggan I've updated the main.bicep to limit the main resource location to the available APIC locations. Devs now can choose the main locations for the new or existing APIC instance.

This has been updated in this README. In addition to that, another PR for Microsoft Learn has been created to the other repo.
