[Hemant]

I am using File Upload Control in blazor web assembly project.
And using .Net 4.6 Web API 2.0 

I am getting CORS Error even if there is CORS setting there in API.

Image file getting stored on Server after that it gives CORS Error

WebAPI Config Setting

All API Call works fine but only file upload giving CORS error on local as well as server

Hi Hemant, 

 

Greetings from Syncfusion support. 

 

To resolve the CORS issue in Blazor WebAssembly Application, we suggest you add httpRequest.SetBrowserRequestMode(BrowserRequestMode.Cors)) to your application.
