Remarks

TIP: Test CORS using: https://www.test-cors.org/

1. Simply configure a global CORS policy for all enddpoints under 'applicationMiddleware' section:

"CORS": {
          "ord": 30,
          "type": "Tlabs.Config.CorsConfigurator, Tlabs.SrvBase",
          "options": {
            "PreflightMaxAge": 120,
            "AllowAnyHeader": true,
            "AllowedOrigins": ["http://localhost:8086", "http://*.pol-it.de"]
           }
        }

2. Configure a named CORS policy with section 'applicationServices'

"applicationServices": {
          "CORS": {
            "type": "Tlabs.Config.CorsConfigurator, Tlabs.SrvBase",
            "options": {
            "PreflightMaxAge": 120,
            "AllowAnyHeader": true,
            "AllowedOrigins": ["http://localhost:8086", "http://*.pol-it.de"]
          }
        },

... and use this policy with the attribut {EnableCors] in your controller:

[Route("api/[controller]")]
        [ApiController]
        public class WidgetController : ControllerBase {
        // GET api/values
        [EnableCors("TlabsCORSappPolicy")]
        [HttpGet]
        public string Get() { ... }
