input: [Category] Data Contracts [Description] While WCF lets you freely pass ADO.NET data tables to and from a service, it is a questionable practice at best if the service needs to work with non-.NET clients. It is better in such cases to rerun the items in a neutral array. The solution demonstrates the use of the IDesign helper class DataTableHelper which converts the table to an array.
