I work with DataSets quite a bit, and I'm a fan of the DataSet visualizers that were available for VS 2003: The DataSet QuickWatch and the XML Visualizer were two that I used a lot. In particular, XML Visualizer allowed you to display all of the different data versions available in a DataRow.
Visual Studio 2005 ships with a DataSet visualizer, but it doesn't make all of the row versions available, nor does it show the row state. So, I decided to learn how to write a visualizer for VS2005. My DataSet visualizer shows row state and all of the available row versions. No editing of the data (yet). Download it here.
