The service is setting the policy with the config file.

The Client used to work when set with the config file. Now I am trying
to implement it with code.

/////////////////////////////////
//Test Set By Config    THIS WORKED
           // Set the ClientPolicy onto the proxy
           //serviceProxy.SetPolicy("ClientPolicy");

/////////////////////////////////
//Test Set By Code DOES NOT WORK first error is that signature cannot
be nul
           X509SecurityToken oX509CT = RetrieveTokenFromStore2("My",
StoreLocation.CurrentUser, "CN=WSE2QuickStartClient");
           MessageSignature oSignature = new
MessageSignature(oX509CT);

serviceProxy.RequestSoapContext.Security.Elements.Add(oSignature);

           serviceProxy.SetClientCredential(oX509CT);

           X509SecurityToken oX509CTS =
RetrieveTokenFromStore2("AddressBook", StoreLocation.CurrentUser,
"CN=WSE2QuickStartServer");
           EncryptedData oEncryptedData = new EncryptedData(oX509CTS);

serviceProxy.RequestSoapContext.Security.Elements.Add(oEncryptedData);

           serviceProxy.SetServiceCredential(oX509CTS);

      // Create a new policy.
           Policy oWebServiceClientPolicy = new Policy();

           // Specify that the policy uses the MutualCertificate11
turnkey security assertion.
           MutualCertificate11Assertion oMCA = new
MutualCertificate11Assertion();
           oMCA.EstablishSecurityContext = false;
           oMCA.RenewExpiredSecurityContext = true;
           oMCA.RequireSignatureConfirmation = true;
           oMCA.MessageProtectionOrder =
MessageProtectionOrder.SignBeforeEncrypt;
           oMCA.RequireDerivedKeys = false;
           oMCA.TtlInSeconds = 300;
           oMCA.Protection.Request.SignatureOptions =
SignatureOptions.IncludeAddressing
                                                       |
SignatureOptions.IncludeTimestamp
                                                       |
SignatureOptions.IncludeSoapBody;
           oMCA.Protection.Request.EncryptBody = true;
           oMCA.Protection.Response.SignatureOptions =
SignatureOptions.IncludeAddressing
                                                       |

           oMCA.Protection.Response.EncryptBody = true;
           oWebServiceClientPolicy.Assertions.Add(oMCA);

           // Apply the policy to the SOAP message exchange.
           serviceProxy.SetPolicy(oWebServiceClientPolicy);

//End Test Set By Code

           String[] symbols = {"FABRIKAM", "CONTOSO"};
           StockQuote[] quotes =
serviceProxy.StockQuoteRequest(symbols);

I would appreciate any help!
