I read somewhere in stackoverflow itself that when we use POCO classes for WCF contracts using Poco generator , we need not use DataContract and DataMember attributes.WCF do it auto for you? . I don't know how it manages this.
I created a sample application without using these attributes and I was able to generate those entities on client side and use them. I disabled proxy generation and Lazy loading.
Am i missing anything here.? Is there really no need of putting these attributes.
