IsReference property in data contract

Question

What is the purpose of IsReference property in DataContract? How does the request and response vary with this property applied?

Answer 1

Also IsReference does not exist in .NET Framework 3.5. So you could get errors when using it with that Framework version - it only exists in 4.5, 4, 3.5 SP1 and Silverlight.

"Error 297 'System.Runtime.Serialization.DataContractAttribute' does not contain a definition for 'IsReference' "
