Another easy way to configure CORS on Azure Functions is to use Azure Portal,

2 - Click on CORS and add your local host url

And there you have it!!

Hope this helps someone.

You can configure CORS in the local settings file local.settings.json:

{
  "Values": {
  },
  "Host": {
    "CORS": "*"
  }
}

Settings in the local.settings.json file are used only when you're running projects locally

You can start the host like this

func host start --cors *

You can also be more specific and provide a comma delimited list of allowed urls
