In WCF you can define a contract using the [DataContract] and [DataMember] attributes, like this: [DataContract] public class Sample { [DataMember(EmitDefaultValue = false, IsRequired = false)] public string Test { get; set; } } This article on the MSDN states that using EmitDefaultValue = false is not recommended: However, i like to use this, because the XML that is generated using this construction is cleaner. Not specifying this setting results in: <Sample> <Test xsi:nil="true"/> </Sample> while using the setting the element is ommited when there is no value: <Sample> </Sample> I'm curious

I am looking to place attributes on my WCF data contract members to validate string length and possibly use regex for more granular parameter validation. I can the [Range] attribute for numeric and DateTime values and was wondering if any of you have found any other WCF Data Member attributes I can use for data validation. I have found a bevvy of attributes for Silverlight but not for WCF. Add System.ComponentModel.DataAnnotations reference to your project. The reference provides some DataAnnotations which are: RequiredAttribute, RangeAttribute, StringLengthAttribute,

I use [DataMember(IsRequired=true)] to make the DataContract properties required. There doesn't seem to be some IsRequired for the OperationContract parameters. How do I make them required and not allow null? The parameter in of OperationContract appears to be optional in SoapUI tool. Though this must never be optional or null. WCF Interface: [OperationContract] IsClientUpdateRequiredResult IsClientUpdateRequired(IsClientUpdateRequiredInput versie); ... [DataContract] public class IsClientUpdateRequiredInput { [DataMember(IsRequired=true)] public string clientName { get; set; } [DataMember

I have a server side class which I make available on the client side through a [DataContract]. This class has a readonly field which I'd like to make available through a property. However, I'm unable to do so because it doesn't seem that I'm allowed to add a [DataMember] property without having both get and set. So - is there a way to have a [DataMember] property without setter? [DataContract] class SomeClass { private readonly int _id; public SomeClass() { .. } [DataMember] public int Id { get { return _id; } } [DataMember] public string SomeString { get; set; } } Or will the solution be use
