Thank you for your prompt replies in this thread BUT your sample does NOT work on MacOS, Safari 16.1 (17622.214.171.124.13, 17614). Your sample is using Syncfusion.EJ2.AspNet.Core version 126.96.36.199 and still, when run, the collection of files posted to the controller is null.
The above code works fine on Windows (Chrome browser). But on Safari, the error is:
System.NullReferenceException HResult=0x80004003 Message=Object reference not set to an instance of an object. Source=webapp1 StackTrace: at webapp1.Controllers.HomeController.d__4.MoveNext() in HomeController.cs:line 36

Dimitris, after validating the requirement on the latest updated sample, the sample has old version scripts. After updating the latest version scripts in the _Layout.cshtml page the reported issue does not occur.
