I\'m working on trying to ftp a file to the server through a silverlight application. Where the location to upload the file on server file system, exists outside the sandbox
In the meantime, name it Silverlight 5, Sockets got an update: with ClientAccessPolicy.xml the port-range got boosted and an in-browser elevated-trust mode is available.
Therefore I've created sharpLightFtp to enable rudimental Ftp.
