We have an BCS issue on a Sharepoint Foundation multi-tenant farm.
Users are able to create external content types using SharePoint Designer 2010, but when they browse to the list of external data we see an error stating "Unable to display this Web Part"
In the ULS logs is see System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Office.SecureStoreService, Version=14.0.0.0
Anyone have an idea?
