In my case i simply missed to add multipart/form-data in my form.

If your controller is accepting uploaded files using IFormFile but you find that the value is always null, confirm that your HTML form is specifying an enctype value of multipart/form-data. If this attribute isn't set on the element, the file upload won't occur and any bound IFormFile arguments will be null.

Example:-

        

            

                
Upload one or more files using this form:
                
            
        
        

            

                
            
        
    

Remove the multiple attribute on this input element to allow just a single file to be uploaded.
