IFormFile always return null in asp.net core 2.1

Question

Api method is looks like below

    [HttpPost]
    public async Task> MediaBrand(IFormFile file, int brandId)
         


        

Answer 1

I have found a workaround to make it work:

Use HttpPut instead of HttPost on the controller action.

I was also surprised by this behavior. If someone can explain why it fixes the issue, it would help me.
