I have a package design with Visual Studio 2008 that reads a SharePoint List into a SQL Server table, does some data manipulations, and then updates two columns of the SharePoint List. This was done using the SharePoint adapters available on CodePlex, and the package has been running daily for a few months without any issue.
Since we've migrated our SQL Server databases to 2012, we would like to upgrade our SSIS packages to Visual Studio 2010 as well, and I had read that the SharePoint Source and Destination connections are now built into the Integration Services Toolbox. And, indeed they are. However, when I try to use the Destination connection, and hit the Refresh button in the Advanced Editor, I receive an error that says, in part: System.InvalidOperationException: Sequence contains more than one element at System.Linq.Enumerable.SingleOrDefault[TSource](IEnumerable1 source) at Microsoft.Samples.SqlServer.SSIS.SharePointListAdapters.SharePointListDestination.CreateExternalMetaDataColumns . . . etc.
As a result, not all of the columns from the SharePoint List are avilable for mapping, missing (of course!) a couple of the columns that I am updating!
At the same time, my 2008 package ran normally this morning, and it reads and writes from the same SharePoint List (there is only one that I'm using).
Has anyone run into the same sort of difficulty upgrading the SharePoint Adapters from 2008 to 2010? Any suggestions, comments, advice?
Thanks in advance,
Larry
