I would need to have a library (.dll) and the complete source file of code to start a FTP server in C#. Job should be done in .Net 4.0. The FTP server should support following methodes:
-File Transfer in both directions
-standart commands (renamefile, remove file)
-should be able to run great using "Filezilla" (as told above exotic features doesn't need to be supported, we will talk after we've got a contract)
For example changing permissions on files wouldn't be needed, in this case the FTP server should display just the correct code of "feature not implemeted", regarding to the FTP protocol standarts.
Dll should be easy to use and be able to catch errors.
