Where obtain 2008 Dataset Designer?

Question

I would like to know where the dataset designer is obtained for a C#.net 2008 application I need to work on.
Is this part of the initial install for visual studio.net 2008. If so, what part of the initial install will I find the dataset designer?
Is this a plugin that needs to be downloaded? if so, what URL do I need to use to obtain the plugin?
Basically my company just purchased a new licesnse for me to use Visual Studio.net 2008 professional edition. I need to modify some tables that are behind a current application. When I use this new version of Visual studio.net 2008, I can not find an .xsd file that I can open with a desinger to see all the tables that are used in this application. I know there is a designer with this application, since I can not step through this code. The 'designer' generated the code I can not step through.

It's an inherent part of the IDE. It should be present automatically with Visual Studio.net 2008 professional edition. Click on the .xsd file in the solution explorer and select Open in the context menu. This should show up in the DataSet Designer.
