Drag-n-Drop File Upload in ASP.NET Core

In one of my earlier articles I discussed how to upload files using full page post-back as well as Ajax post-back. Usually developers use the file input field to select one or more files to be uploaded from the client machine. However, you can also HTML5 drag-n-drop to make it east for the end user to pick files directly from Windows explorer. To that end this article shows how to implement just that.
