I'm trying to get the sample FedEx Address Verification application to work in C#. After contacting my FedEx technical contact and having him activate Address Verification on my test account (apparently it is considered an advanced service that requires additional permissions) I was able to compile and run the example application.

However, I wasn't getting quite the results I expected given the settings...

```
request.Options.ConvertToUpperCase = true;
request.Options.CheckResidentialStatus = true;

```

Based on these flags, I expected to have the address come back in upper case, and to be able to check the Residential or ResidentialStatus properties to determine commercial vs residential. Neither were occuring.

So I installed Fiddler to see the exact SOAP exchange that was taking place and found that the outbound Options tag was not populating except for one property, MaximumNumberOfMatches.

Is there something I should check for in the Reference.cs file that is created by Visual Studio? I didn't see anything out of the norm, but something is happening that is preventing the serialization of some of the properties.

--Edit--

Updated my code as per the suggestion below. Unfortunately, it still only populates 2 of the options parameters. I've included the C# settings code and the outbound/inbound SOAP request below. Can anyone think of a reason the rest of the options are not being sent in the SOAP request?

```
AddressValidationRequest request = new AddressValidationRequest();
            //
            request.WebAuthenticationDetail = new WebAuthenticationDetail();
            request.WebAuthenticationDetail.UserCredential = new WebAuthenticationCredential();
            request.WebAuthenticationDetail.UserCredential.Key = "XXX-KEY-XXX"; // Replace "XXX" with the Key
            request.WebAuthenticationDetail.UserCredential.Password = "XXX-PWD-XXX"; // Replace "XXX" with the Password
            //
            request.ClientDetail = new ClientDetail();
            request.ClientDetail.AccountNumber = "XXX-ACCT#-XXX"; // Replace "XXX" with client's account number
            request.ClientDetail.MeterNumber = "XXX-MTR#-XXX"; // Replace "XXX" with client's meter number
            //
            request.TransactionDetail = new TransactionDetail();
            request.TransactionDetail.CustomerTransactionId = "***Address Validation v2 Request using VC#***"; // This is just an echo back 
            //
            request.Version = new VersionId(); // Creates the Version element with all child elements populated
            //
            request.RequestTimestamp = DateTime.Now;
            //
            request.Options = new AddressValidationOptions();
            request.Options.CheckResidentialStatus = true;
            request.Options.CheckResidentialStatusSpecified = true;
            request.Options.VerifyAddresses = true;
            request.Options.MaximumNumberOfMatches = "5";
            request.Options.StreetAccuracy = AddressValidationAccuracyType.MEDIUM;
            request.Options.DirectionalAccuracy = AddressValidationAccuracyType.MEDIUM;
            request.Options.CompanyNameAccuracy = AddressValidationAccuracyType.MEDIUM;
            request.Options.ConvertToUpperCase = true;
            request.Options.RecognizeAlternateCityNames = true;
            request.Options.ReturnParsedElements = true;
            //
            request.AddressesToValidate = new AddressToValidate[2];
            request.AddressesToValidate[0] = new AddressToValidate();
            request.AddressesToValidate[0].AddressId = "Kimmel";
            request.AddressesToValidate[0].Address = new Address();
            request.AddressesToValidate[0].Address.StreetLines = new String[1] { "425 Morningside Dr" };
            request.AddressesToValidate[0].Address.City = "Deerfield";
            request.AddressesToValidate[0].Address.PostalCode = "53531";
            request.AddressesToValidate[0].Address.CountryCode = "US";
            //
            request.AddressesToValidate[1] = new AddressToValidate();
            request.AddressesToValidate[1].AddressId = "WD";
            request.AddressesToValidate[1].Address = new Address();
            request.AddressesToValidate[1].Address.StreetLines = new String[1] { "2830 Progress Rd" };
            request.AddressesToValidate[1].Address.PostalCode = "53716";
            request.AddressesToValidate[1].CompanyName = "Wingra Direct";

```
