C# & ASP.NET - Anyone create a library to talk to EdgeCast CDN via FTP?

Question

For one of my projects we utilize a Content Delivery Network ( EdgeCast ) and I was wondering if anyone knew of an existing (open source) library for C# that we could leverage? In a nutshell, I am investigating the ability to create directories, upload files, and allow some general maintenance (rename files, delete files) via our admin panel. Any insight would be appreciated.

NOTE : My code to do this. I don't know if they have an updated API at this point so please check. This code is circa 2009 (as-is, no warranties, use at your own risk, etc).

Never mind. I created a FTP library and used what little they had for an API. I can not now read/upload/delete files and purge the CDN.
