C# Runtime Error when implementing WSSE Security Headers with custom fields in SOAP request

Question

I am trying to send a SOAP request to a web service that uses WSSE and UsernameToken for authentication. The sample query is as follows (ma

Answer 1

I think is the xml structure punctually the headers when you use

<wsse:Security wsse is not defined, I know you defined in the same line but why not try put it on the document, something like this

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:kas="http://webservice.com" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
   <soapenv:Header>
      <wsse:Security>
         <wsse:UsernameToken>
            <wsse:Username>abc</wsse:Username>
            <wsse:CustomField>123</wsse:CustomField>
         </wsse:UsernameToken>
      </wsse:Security>
   </soapenv:Header>

I decided to utilize a different method and quit trying to use a proxy class for the time being as there were problems associated with it. Making use of the answers on this link: Client to send SOAP request and receive response I came up with my own solution after some customization.

However, I still wonder how to proceed in order to make it work using wrapper classes defined by Visual Studio or WSE 3.0. After writing the code and testing it in Visual Studio it was pretty easy to port it into Blue Prism.
