Preparing the test project

Let's prepare the project by following these steps:

1. In the already created project (refer to the Technical requirements section), we will now create a new empty API controller with a small action inside:

   namespace ModelBinderSample.Controllers
   {
       [Route("[controller]")]
       [ApiController]
       public class PersonsController : ControllerBase
       {
           public ActionResult<object> Post(
               IEnumerable<Person> persons)
           {
               return new
               {
                   ItemsRead = persons...
