This is a Web Forms example of how to consume the Openstack NET SDK V1 : http://openstacknetsdk.org/.

    When uploading a file it's temporarily stored in a temp directory so be sure to have appropriate 
permissions in place for read/write or if using Rackspace Cloud Sites be sure to add impersonation 
to your web.config so the file system can upload the file.
    
    I hope my example helps!
