thanks,

Folks, I figured out the fix.

Pre:
Clean up the project by removing the extra file (myDataSet1.Designer.cs) and saving everything in the desired state.  I also killed my myDataSet.Designer.cs, so I was ensured a new generated file was created.

1) Save and close VS
2) Open the project file (.csproj/.vbproj) with a text editor
3) Search for the name of the DataSet and edit the LastGenOutput:

    <None Include="myDataSet.xsd">
      <SubType>Designer</SubType>
      <Generator>MSDataSetGenerator</Generator>
      <LastGenOutput>myDataSet1.Designer.cs</LastGenOutput>
    </None>

What caused this duplicate file?  I think it was a combination of a manual edit of the XSD, VSS, and a ReadOnly designer file.  At which point, VS attempted to find an available filename.
