    Hi @azure ,

    You need to add CORS to your API app service either through the portal or running the CLI command az webapp cors add --resource-group myResourceGroup --name <app-name> --allowed-origins 'http://localhost:4200'. After you deploy your angular app, you will want to either add the URL of the app or '*' to the allowed origins.
