File upload in MVC6 with drag and drop behavior

I need to upload files in MVC6 with drag and drop behavior. It means user will not browse through and select a file - but rather drag and drop the files from his pc to a section of web page.

I got this link and it is working perfectly fine when users opens up and selects a file through input type file control - but how can I achieve the same with drag and drop.

Any suggestion would be of much help
