TypedMapper.Open<T> Method (IAppContext, String, Flavors, MapperAttrs)

Creates a new mapper and moves to the first record. This method is intended for opening a single record. You should generally use an OpenReader<T> (IAppContext, String, Flavors, MapperAttrs, String, MapperLoadFlags, Int32) method for iterating through a variable number of records. You must explicitly call Close() or Dispose() on the object after this call.
