Enumeration class like Microsoft.Crm.Sdk.MessageName

I noticed that in CRM 2011 SDK is no class like Microsoft.Crm.Sdk.MessageName.
But among other entities there is SdkMessage entity. So you are able to read all available messages using Organization service. But I think if you want to have a class like Microsoft.Crm.Sdk.MessageName you can generate it. Below I wrote console application code to generate MessageName class from retrieved from CRM SdkMessage list.

private const string ORGANIZATION_URL_SETTING = "organizationUrl";
private const string CLASS_NAME = "MessageName";
const string NAMESPACE_NAME = "YourNamespaceName";


static void Main(string[] args)
{
  Uri organizationUri = new Uri(CrmMessagesClassGenerator.Properties.Settings.Default.organizationUrl);
  ClientCredentials credentials = new ClientCredentials(); ;
  credentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;


  using (Microsoft.Xrm.Sdk.Client.OrganizationServiceProxy _serviceProxy = new OrganizationServiceProxy(organizationUri,
null,
credentials,
null))
  {
// This statement is required to enable early-bound type support.
_serviceProxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior());


IOrganizationService _service = (IOrganizationService)_serviceProxy;


System.IO.StreamWriter file = new System.IO.StreamWriter(CLASS_NAME + ".cs");


file.WriteLine("namespace " + NAMESPACE_NAME);
file.WriteLine("{");
file.WriteLine("  public static class " + CLASS_NAME);
file.WriteLine("  {");


LoadMessages(_service, file);


file.WriteLine("  }");
file.WriteLine("}");


file.Close();
  }


}


public static void LoadMessages(IOrganizationService _service, System.IO.StreamWriter file)
{
  //Generate the query
  ConditionExpression con = new ConditionExpression();
  con.AttributeName = "isprivate";
  con.Operator = ConditionOperator.Equal;
  con.Values.Clear();


  con.Values.Add(false);


  OrderExpression order = new OrderExpression();
  order.AttributeName = "name";
  order.OrderType = OrderType.Ascending;


  QueryExpression query = new QueryExpression();
  query.ColumnSet = new ColumnSet(true);
  query.Criteria = new FilterExpression();
  query.Criteria.Conditions.Clear();


  query.Criteria.Conditions.Add(con);


  query.EntityName = SdkMessage.EntityLogicalName;
  query.Orders.Clear();
  query.Orders.Add(order);


  //Retrieve the message entities
  DataCollection<Entity> ent = _service.RetrieveMultiple(query).Entities;
  Entity[] messageEntityList = new Entity[ent.Count];
  ent.CopyTo(messageEntityList, 0);


  //Process each message entity
  for (int i = 0; i < messageEntityList.Length; i++)
  {
SdkMessage mes = (SdkMessage)messageEntityList[i];
file.WriteLine("    public const string " + mes.Name + " = \"" + mes.Name + "\";");
  }
}

and also result of this application:
