[DataFrame] IDataView <-> DataFrame Interop #2192
Description
Interop between the IDataView and DataFrame is currently possible except when working with the following types:
- VectorDataViewType
- DateTimeDataViewType
- KeyDataViewType (UInt)
This causes calls to .ToDataFrame() to throw an error.
Add support for the data types listed above to enable deeper interop between DataFrame and IDataView.
