Restore Cache bug

   Hi,

DevForce fails to restore an entity set restored into Silverlight from a desktop model containing an IdGenerator.

Additional information: Element 'http://ideablade.com/EntityModel:NextIdGenerator' contains data of the 'http://schemas.datacontract.org/2004/07/Northwind.Model:NumericIdGenerator' data contract. The deserializer has no knowledge of any type that maps to this contract. Add the type corresponding to 'NumericIdGenerator' to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding it to the list of known types passed to DataContractSerializer.

The solution to this is to create a dummy generator in Silverlight:

    [DataContract]
    public class NumericIdGenerator1 : IIdGenerator
    {
        public bool IsApplicable(IDataSourceKey dataSourceKey)
        {
            return false;
        }

        public object GetNextTempId(DataEntityProperty property)
        {
            return null;
        }

        public bool IsTempId(UniqueId uniqueId)
        {
            return false;
        }

        public void Reset()
        {
            return;
        }

        public UniqueIdMap GetRealIdMap(UniqueIdCollection tempIds, IDataSourceKey dataSourceKey)
        {
            return null;
        }

        public UniqueIdCollection TempIds
        {
            get { return null; }
        }
    }
