Constructor in WCF DataContract not reflected on Client

I need to have some data members get some values when I create an instance of the DataContract on the client. This is not happening using constructors. I have searched through different forums and found we have to use [OnDeserializing] and [OnDeserialized] attributes. This is also not working. Can somebody suggest something here. The other alternative is creating constructors in the partial classes at the client side. I want to avoid that.

Please find the code below:

Server-side: Datacontract

[DataContract]
public class Account
{

    private int mAccountId;
    private string mAccountName;

    public Account()
    {
        mAccountId = 5;
        mAccountName = "ABC";
    }

    [OnDeserializing]
    public void OnDeserializing(StreamingContext context)
    {
        mAccountId = 5;
        mAccountName = "ABC"; 
    }

    [OnDeserialized]
    public void OnDeserialized(StreamingContext context) 
    {

    } 

    [DataMember]
    public int AccountId
    {
        get
        {
            return mAccountId;
        }
        set
        {
            mAccountId = value;
        }
    }

    [DataMember]
    public string AccountName
    {
        get
        {
            return mAccountName;
        }
        set
        {
            mAccountName = value;
        }
    }


}

Client side - initialization

namespace TestClient
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Account acc = new Account();

        }
    }
}

make Proxy class in your client side:

public class AccountProxy: Account
{
   public AccountProxy()
   {
         mAccountId = 5;
         mAccountName = "ABC";
   }
}

and use your proxy class, not generated client class:

namespace TestClient
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            AccountProxy acc = new AccountProxy();

        }
    }
}
