аннотации данных, такие как RequiredAttribute, DisplayAttribute и т. Д., Не распространяются на сгенерированные файлы на стороне клиента при использовании Silverlight 4 и WCF.
Это одно из решений проблемы ...
Создать библиотеку классов с моделью (Model.dll)
образец
public partial class Person: INotifyPropertyChanged
{
private Guid IDField;
private string NameField;
private string LastNameField;
private int AgeField;
private string EmailField;
/// <summary>
/// ID of an Object
/// </summary>
public Guid ID
{
get
{
return IDField;
}
set
{
if (value != IDField)
{
Validator.ValidateProperty(value, new ValidationContext(this, null, null) { MemberName = "ID" });
IDField = value;
OnPropertyChanged("ID");
}
}
}
/// <summary>
/// Name of a person
/// </summary>
[Required]
public string Name
{
get
{
return NameField;
}
set
{
if (value != NameField)
{
Validator.ValidateProperty(value, new ValidationContext(this, null, null) { MemberName = "Name" });
NameField = value;
OnPropertyChanged("Name");
}
}
}
/// <summary>
/// LastName of a person
/// </summary>
[Required]
public string LastName
{
get
{
return LastNameField;
}
set
{
if (value != LastNameField)

LastNameField = value;
OnPropertyChanged("LastName");
}
}
}

[Range(0,120)]
//[Required]
public int Age

{
if (value != AgeField)
{
Validator.ValidateProperty(value, new ValidationContext(this, null, null) { MemberName = "Age" });
AgeField = value;
OnPropertyChanged("Age");
}
}
}
[RegularBLOCKED EXPRESSION]
public string Email
{

Создание библиотеки классов silverlight (SL.Model.dll) (в этой библиотеке есть образец модели, созданный в Model.dll)
в этой библиотеке классов добавьте существующий элемент как ссылку и добавьте элемент модели, имеющий Model.dll
в приложении Silverlight ссылка на файл SL.Model.dll
когда ссылка на сервисы является представлением создания, которое проверяет повторное использование типов (это вариант по умолчанию)
