Converting asp:Silverlight tag to object tag for Silverlight 3

Greetings,

I found this quite painful but was able to piece together a solution. If you want to pass a clientToken from a silverlight 3 object instead of a silverlight 2 asp control here is the default.aspx and default.aspx.cs code:

default.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="dashboard.Web.Default1"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<head id="Head1" runat="server">

	    overflow: auto;
    }
    body {
	    padding: 0;
	    margin: 0;
    }
    #silverlightControlHost {
	    height: 100%;
	    width: 100%;
	    text-align:center;
    }
    </style>
    <script type="text/javascript" src="Silverlight.js"></script>
    <script type="text/javascript">
        function onSilverlightError(sender, args) {
            var appSource = "";
            if (sender != null && sender != 0) {
              appSource = sender.getHost().Source;
            }
            
            var errorType = args.ErrorType;
            var iErrorCode = args.ErrorCode;

            if (errorType == "ImageError" || errorType == "MediaError") {
              return;
            }

            var errMsg = "Unhandled Error in Silverlight Application " +  appSource + "\n" ;

            errMsg += "Code: "+ iErrorCode + "    \n";
            errMsg += "Category: " + errorType + "       \n";
            errMsg += "Message: " + args.ErrorMessage + "     \n";

            if (errorType == "ParserError") {
                errMsg += "File: " + args.xamlFile + "     \n";
                errMsg += "Line: " + args.lineNumber + "     \n";
                errMsg += "Position: " + args.charPosition + "     \n";
            }
            else if (errorType == "RuntimeError") {           
                if (args.lineNumber != 0) {
                    errMsg += "Line: " + args.lineNumber + "     \n";
                    errMsg += "Position: " +  args.charPosition + "     \n";
                }
                errMsg += "MethodName: " + args.methodName + "     \n";
            }

            throw new Error(errMsg);

I tried this to get hold of the token - but still having problems getting a succesful token into my silverlight Page

In my App.Xaml.Cs under Application_Startup method I now have

this.RootVisual = new Page(e.InitParams["clientToken"]);

And then within Page.xaml.cs I have the folliwing in my Page constructor

public Page(string Token)
TheClientToken = Token
.....

RouteService.Credentials MyCredentials = new RouteService.Credentials();
MyCredentials.Token = TheClientToken;

Under debug a long Token String is being passed through, but the resulsts of my CalculateRouteAsync call always returns "Credentials are either Invalid or Unspecified" errors in my Silverlight page.
- I have checked that I am calling the corrrect staging version of the Route Service
- I have checked my Credentials when calling Route Servcie from within aspx server side controls, which resturns results OK.

So it iss soimthing to do with corrupting my Token , in the transfer from Default.aspx to the Silverlight Control. Even though thr Token 'looks OK' within Debug.

Any suggestions ?
Cheers
