/// \brief
/// The IConnectionPropertyDictionary exposes a dictionary style interface
/// to the connection properties. The properties required to establish a connection
/// can be determined and their values can be set through this interface.
/// Modifying connection properties through this
/// interface dynamically modifies the connection string held by the connection
/// object. When the connection is in an open state, calling SetProperty on this
/// interface will result in an error.
