void InitializeViewModel(MyEntity entity)
{
    Type objectType = entity.GetType();
    var properties =
    entity.GetType().GetProperties().Where(p => p.PropertyType.IsClass
               && !p.PropertyType.FullName.StartsWith("System."));

    foreach (PropertyInfo propertyInfo in properties)
    {
         var instance = Activator.CreateInstance(propertyInfo.PropertyType);
         objectType.GetProperty(propertyInfo.Name).SetValue(entity, instance);
    }
}
