Merge on typed datasets not working any more!6/12/2006 12:54:47 PM

0/0

I've just converted my project from VS2003 to a web application on VS2005; most things seem to have converted across fine.  The main outstanding issue I have is the Merge functionality on my Typed Datasets no longer seems to work.  The code is very simple, and worked perfectly in v1.1

// Filter rows
Venue.VenueFoodItemsRow[] foundRows = 
   (Venue.VenueFoodItemsRow[])venue.VenueFoodItems.Select("MenuType=" + m_MenuType_ID);

// Clear existing rows
venue.VenueFoodItems.Clear();

// Merge back into the dataset
venue.Merge(foundRows, false, MissingSchemaAction.Ignore); // Not working any more

The foundRows[] array has a length of one, so the SELECT is working, and there are 8 tables in the venue dataset before and after the merge.  Has anyone come across this problem before, and found a solution?  I'm completely at a loss here!

Thanks in advance!

I haven't heard of this issue before, so I'm at a loss of what might be happenening.  If you can create a very simple VS2003 project that exhibits this behavior, and can send me a zip file of the VS2003 project I can try it out and see if there's a specific issue here.  You can send it to me at omark-at-microsoft-dot-com.  Thanks.
