I have a business logic object the is used to update a data source using an
untyped dataset that is passed to it. It is much easier and readable to use
a typed dataset in the UI portion of my code. There is no schema change
between the two datasets. What is the best way to convert a typed dataset
to an untyped dataset?

What about this:

Dim ds1 As New MyTypedDataSet()
Dim ds2 As DataSet

ds2 = CType(ds1, DataSet)
