Incorrect: Not D: The RunDate attribute is defined as DateTime, but the timestamp (the time of day), should not be displayed.

Answer: A, D Question: 17 You You are designing a Windows Communication Foundation Foundat ion (WCF) service that uses the Product class.

Mark the Product class with the DataContract DataContract attribute. B. Mark Mark the the publ public ic memb member ers s of the the Prod Produc uctt clas class s with with the the Data DataCo Cont ntra ract ctFo Forma rmatt attribute. C. Mark the Product class with the CollectionDataContract attribute. D. Mark the public members of the Product class with the DataMember attribute.

Answer: A, D So as of .NET 3.5 SP1, you don't have to add data contract or data member attributes anym anymor ore e - if you you don' don'tt then then the the data data cont contra ract ct seri serial aliz izer er will will seri serial aliz ize e all all publ public ic properties on your class, just like the XML serializer would. HOWEVER: by not adding those attributes, you lose a lot of useful capabilities:


 

without [DataContract], you cannot define an XML namespace for your data to live in without [DataMember], you cannot serialize non-public properties or fields

without [DataMember], you cannot define an order of serialization (Order=) and the DCS will serialize all properties alphabetically with withou outt [Dat [DataM aMem embe ber] r],, you you cann cannot ot defi define ne a diff differ eren entt name name for for your your prop proper erty ty (Name=) witho without ut [DataM [DataMemb ember] er],, you you cannot cannot define define things things like like IsRequ IsRequire ired= d= or other other useful useful attributes witho without ut [DataM [DataMemb ember] er],, you you cannot cannot leave leave out certai certain n public public proper propertie ties s - all public public properties will be serialized by the DCS 
