Question Web Service SOAP Calls is adding something odd when sending request

[RoboticBD]

So I posted something last week about an issue I was having with no response so I am hopeful I can get and answer. So this time it was determined on what was happening. When I use SOAPUI and send a request with the username parameter, I was getting the information back. When I call the same request in VB .NET I would get an erro back. from the Web server.
We found that VB.NET is adding this "xsi:type="xsd.string" in the <username> brackets. The code is below. First what SOAPUI s sending and the second is what VB is sending. How do I stop the issue from doing this?


This is what SOAPUI sends

<soap:Body soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
      <q1:GetEmailFromUsername xmlns:q1="http://MyServer.com>
         <Username>MyName</Username>
      </q1:GetEmailFromUsername>
   </soap:Body>

This is what VB.NET is sending

<soap:Body soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
      <q1:GetEmailFromUsername xmlns:q1="http://MyServer.com>
         <Username xsi:type="xsd.string">MyName</Username>
      </q1:GetEmailFromUsername>
   </soap:Body>

Thanks,
