Answer 1

Issue is this

https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=362994

When using the Dataset Visualiser to display a Dataset with multiple tables error providers are seen instead of the expected data when switching tables.

The initial table displays correctly. After switching to another table only the first line of data is displayed. every other line has an error provider with the error 'Debugger busy. Can't get value'.

This behaviour has been seen on multiple PCs since installing Service Pack 1 for VS2008.

If the window is resized so that the visualizer grid is not visble when the table is changed then the data is shown correctly.CommentsThanks for your feedback. We are escalating this bug to the product unit who works on that specific feature area. The team will review this issue and make a decision on whether they will fix it or not for the next release.
