and available for download. Beside adding the migration support for Google Apps it adds a few bugfixes, as well as a slightly streamlined object model for CellFeeds (Spreadsheets). There is a longer example for this in clients/cs/src/unittests/spreadsheetlive.cs, and the changes are in the realease notes, nethertheless, here is a short example of how you go about getting the feed, adding a new Worksheet, and filling it now:

SpreadsheetFeed feed = service.Query(query); SpreadsheetEntry entry = feed.Entries[0] as SpreadsheetEntry; WorksheetFeed sheets = entry.Worksheets;

WorksheetEntry newEntry = sheets.Insert(new WorksheetEntry(10, 20, "New Worksheet")); CellFeed cells = newEntry.QueryCellFeed(ReturnEmtpyCells.yes); for (uint row = 1; row <= 10; row++) { for (uint col=1; col <= 20; col++) { cells[row,col].InputValue = "R"+row+"C"+col; } } cells.Publish(); // and done. This will do a batchupdate in the background
