title: Send a SOAP request, where to start?
body: <p>I need to send a SOAP request to a URL. But i find this harder then i thought it would be.</p>
  
  <p>The request that i have to send is:</p>
  
  <pre><code>string bla = "" +
  "&lt;?xml version='\"1.0\" encoding=\"UTF-8\"?&gt;" +
      "&lt;soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\"&gt;" +
          "&lt;soap:Body&gt;" +
              "&lt;ns1:sendNotificationResponse" +
                "xmlns=\"http://notification.services.adyen.com\"" +
                "xmlns:ns2=\"http://common.services.adyen.com\"&gt;" +
              "&lt;notificationResponse&gt;[accepted]&lt;/notificationResponse&gt;" +
              "&lt;/sendNotificationResponse&gt;" +
          "&lt;/soap:Body&gt;" +
      "&lt;/soap:Envelope&gt;";
  </code></pre>
  
  <p>I've been given an URL: <a href="https://ca-test.adyen.com/ca/services/Notification?wsdl" rel="nofollow noreferrer">https://ca-test.adyen.com/ca/services/Notification?wsdl</a></p>
  
  <p>The problem is, is that I'm not sure how to go on from here. Can i simply just send a request to that URL? Or do I have to import the WSDL somehow first?</p>
  
  <p>I've found a lot of examples on the net, but I couldn't really make sense out of most of them. Some were even out dated, because they were still using: <strong>Microsoft.Web.Services3</strong></p>
  
  <p>So in short, I'm kinda clueless on what I exactly have to do here and how. I simply want to send that 'SOAP' message... </p>
