Added missing JSON definitions. Replaced all instacnes of XmlElement with XElement (XmlElement not serializable). Replaced all instances of XmlAttribute with string (XmlAttribute not serializable). Removed all pInvoke calls not supported in UWP apps (DNS Server lookups, HTTP access rules and X509 extentions no longer supported).
