The sink provider data is a tree structure of configuration information stored in the <provider> Element (Template) configuration nodes. All sink providers must have a constructor that accepts a IDictionary of properties and a ICollection of these structures if they want to be used from a configuration file.

    private IServerChannelSinkProvider myIServerChannelSinkProviderNew;
