Hi Paul, As it happens I am having the same issue right now.
I am no swig expert at all, but it looks like the vector (OGR) part of the Dataset is specifically NOT defined for C# see https://github.com/OSGeo/gdal/blob/75b443c768b9757085c7c0642e575e1417ccf9dd/gdal/swig/include/Dataset.i#L798-L912 It would be nice to know why this is so, and how much work it is to fix it.
