1. "Avoid inferred data contracts (POCO). Always be explicit and apply the DataContract attribute" (C) Juval Löwy
2. "Use the DataMember attribute only on properties or read-only public members" (C) Juval Löwy
3. Mark [DataMember] only properties, that DO have to be serialized. Avoid marking calculated properties as DataMember
2. Consider using (IsReference = true) on classes to avoid data duplication and circular references.
3. Use short (one or two letters) Name on classes and properties to significantly reduce traffic. (C) Eyal Vardi
4. Specify short Value for EnumMember
5. Use parametrized DataContract property for generic classes
6. Use (EmitDefaultValue=false) on properties to reduce traffic
Sample:
[DataContract(Name="CT")]
public enum CustomerTypes
{
[EnumMember(Value = "I")]
Internal,
[EnumMember(Value = "E")]
External,
[EnumMember(Value = "U")]
Unknown
}
[DataContract(IsReference = true, Name = "B{0}")]
public class BusinessBase<T>
{
T Id { get; set; }
}
[DataContract(IsReference = true, Name = "C")]
public class Customer : BusinessBase<int>
{
[DataMember(Name="C", EmitDefaultValue=false)]
public CustomerTypes CustomerType { get; set; }
[DataMember(Name = "N", EmitDefaultValue = false)]
public string Name { get; set; }
[DataMember(Name = "P", EmitDefaultValue = false)]
public Customer ParentCustomer { get; set; }
public bool IsGoodCustomer
{
get
{
return this.CustomerType == CustomerTypes.Internal || this.CustomerType == CustomerTypes.External;
}
}
