Filepond : c# IFormFile is null : I using [filepond][1] for pretty input file, but I facing issue when submit form.

Before using filepond, in `MyUpload` , the param `uploadedFile` are not null mean getting value.



	<form asp-route="MyUpload" method="post" enctype="multipart/form-data">
		<input class="filepondinput" type="file" name="uploadedFile"/>
	</form>
	$(document).ready(function () {
		$('.filepondinput').filepond();
	});

	//C#
	Task<IActionResult> MyUpload(IFormFile uploadedFile){
		
	}

Below is the code i copy from devtools:

**Before selected any file**

it generate a new input call `filepond--browser` with the name `uploadedFile`

	<div class="filepond--root filepondinput filepond--hopper" data-style-button-remove-item-position="left" data-style-button-process-item-position="right" data-style-load-indicator-position="right" data-style-progress-indicator-position="right" style="height: 67px;">
	    <input class="filepond--browser" type="file" id="filepond--browser-qiu43sah3" name="uploadedFile" aria-controls="filepond--assistant-qiu43sah3" aria-labelledby="filepond--drop-label-qiu43sah3">
	    <div class="filepond--drop-label" style="transform: translate3d(0px, 0px, 0px); opacity: 1;">
	        <label for="filepond--browser-qiu43sah3" id="filepond--drop-label-qiu43sah3" aria-hidden="true">Drag &amp; Drop your files or <span class="filepond--label-action" tabindex="0">Browse</span></label>
	    </div>
	    <div class="filepond--list-scroller" style="transform: translate3d(0px, 0px, 0px);">
	        <ul class="filepond--list" role="list"></ul>
	    </div>
	    <div class="filepond--panel filepond--panel-root" data-scalable="true">
	        <div class="filepond--panel-top filepond--panel-root"></div>
	        <div class="filepond--panel-center filepond--panel-root" style="transform: translate3d(0px, 7px, 0px) scale3d(1, 0.53, 1);"></div>
	        <div class="filepond--panel-bottom filepond--panel-root" style="transform: translate3d(0px, 60px, 0px);"></div>
	    </div><span class="filepond--assistant" id="filepond--assistant-qiu43sah3" role="status" aria-live="polite" aria-relevant="additions"></span>
	    <div class="filepond--drip"></div>
	</div>

**Below is after selected a file**

`filepond--browser` name `uploadedFile` is gone, and a hidden input file with name `uploadedFile` appear

	<div class="filepond--root filepondinput filepond--hopper" data-style-button-remove-item-position="left" data-style-button-process-item-position="right" data-style-load-indicator-position="right" data-style-progress-indicator-position="right" style="height: 69px;">

</div>

This is the reason i think my c# Controller can't receive the param `uploadedFile` , how to solve the input name ?
