Data Services
LINQ to SQL does not support Data Services by default. However, all it takes to use data services with PLINQO is setting the IncludeDataServices property on the Entities template to true and let PLINQO take care of setting up your project to support Data Services.
WCF
PLINQO takes care of all the tedious work of setting up the DataContract and DataMember attributes for Windows Communication Foundation (WCF). The IncludeDataContract option on the Entities template tells PLINQO to generate Data Contract and Data Member Attributes and makes using Windows Communication Foundation (WCF) with PLINQO painless by doing all the leg work.
