Widget Configuration file control is not rendering

Hi, 

We are moving 10.x version to 12.x version and identify one issue with Widget's Configuration issue, I was using the below snip code for rendering file control using configuration which is working fine for 10.x version but not rendering in 12.x version. Please suggest correct code for file upload control.

10.x Version sinip code with demo image

<property id="bg-image_3200" resourceName="CF_postImage_3200" dataType="url" controlType="Telligent.Evolution.Controls.UserFileUrlControl, Telligent.Evolution.Platform">
<propertyRule type="Telligent.Evolution.Controls.PropertyRules.FileExtensionRule, Telligent.Evolution.Platform" validExtensions="gif,jpg,jpeg,png,svg" />
</property>
