Not sure if this is the right NG, if not please point me in the right
direction.

We are developing a clickonce installer for our program Here are my
basic questions:

1.  How can I really debug this?  Simply pressing F5 in VS2005, doesn't
really provide the same environment...for example no Http query string

2.  After publishing to the hard drive if I open publish.htm in IE and
then click on run, nothing happens - it's like it never opens the app.
If I use IE and go directly to the .application file it never opens.
Only if I publish to a website, this makes minor debugging a pain as I
have to repost for every little code change,

3.  Finally, the last question for now.  Our app needs to read the query
string.  in vs2005 I have set it as a full trust application.  When i
run it it generates this exception:
System.NullReferenceException ... Form1.GetQueryStringParameters()

and then the sQuery variable is empty as shown in the MessageBox.  I
have changed publish.htm to be:
directLink = "clickonceinstaller.application?server=foo&test=peter";

Code from form1.cs is:
NameValueCollection aParams;
string sQuery;

private void Form1_Load(object sender, EventArgs e)
{
  aParams = GetQueryStringParameters();
  MessageBox.Show(sQuery);
  if (aParams.Count == 0) { this.Close(); return; }
}

private NameValueCollection GetQueryStringParameters()
{
  NameValueCollection nameValueTable = new NameValueCollection();
  if (ApplicationDeployment.IsNetworkDeployed)
  {
    try
    {
      string queryString =
    ApplicationDeployment.CurrentDeployment.ActivationUri.Query;
      sQuery = queryString;
      nameValueTable =
    System.Web.HttpUtility.ParseQueryString(queryString);
    }
    catch (Exception exception)
      { MessageBox.Show(exception.ToString()); }
  }
  return (nameValueTable);
}

Thanks to all!
