Shift-it (nuget): A HTTP client that can accept a reasonable level of invalid protocol from servers. This is a blocking, synchronous library that uses only .Net sockets, not WebClient or HttpWebRequest, and has a lot of replaceable components. High transfer speeds, and uses minimal memory.  An old and battle hardend FTP client library, works with many old and cranky FTP servers that the standard .Net libraries can't handle.
