Alternative to System.Web.HttpUtility.ParseQueryString that uses a case-insensitive comparer?

If you include a query string on the HREF of the "Launch" link on the publish.htm page that ClickOnce generates when you publish a Windows desktop application:

        HREF="MyWindowsApp.application?ARG1=sis&ARG2=boom&ARG3=bah"

then the query string can be accessed and parsed inside the Windows program:

      if (ApplicationDeployment.IsNetworkDeployed)
        {
            string queryString = ApplicationDeployment.CurrentDeployment.ActivationUri.Query;
            nameValueColl = System.Web.HttpUtility.ParseQueryString(queryString);               
        }

But the NameValueCollection that the HttpUtility parser returns is case-sensitive. A parameter won't be found if you test for it using the wrong case:

        if (ApplicationDeployment.IsNetworkDeployed)
        {
            string queryString = ApplicationDeployment.CurrentDeployment.ActivationUri.Query;
            nameValueColl = System.Web.HttpUtility.ParseQueryString(queryString); 
            if (nameValueColl.AllKeys.Contains("arg1")  ) 
                 {
                     // we don't get here
                 }         ​
       ​}

Is there an alternative to System.Web.HttpUtility.ParseQueryString that uses a case-insensitive comparer?
