Application.Current.Host.Source.Host,

You cannot Navigate() and still use POST. Navigate is the equivalent of clicking a link or typing a URL in the address bar, which invokes the GET verb.

To use POST, you could instead use the Silverlight browser interop to programmatically create an HTML <form>, set its action attribute to the correct URL, set its target attribute to "_blank", add some <input type="hidden"> fields, set their names and values and then submit() the form.

// Get document and body
var doc = System.Windows.Browser.HtmlPage.Document;
var body = doc.Body;

// Create a <form> element and add it to the body
var newForm = doc.CreateElement("form");
newForm.SetAttribute("action", targetUrl);
newForm.SetAttribute("method", "post");
body.AppendChild(newForm);

// TODO: doc.CreateElement("input");
// TODO: SetAttribute("type", "hidden");
// TODO: SetAttribute("name", someName);
// TODO: SetAttribute("value", someValue);
// TODO: newForm.AppendChild()

newForm.Invoke("submit");
