    Debugging with Firefox?

    May 05, 2007 10:25 PM | LINK

    I was just trying out debugging with Silverlight and noticed that if I targeted Firefox as my default browser, debugging would start immediately quit (although the silverlight app still came up in firefox). I had to set my default browser to IE before debugging would work. Is there a work-around for this, is it a side-effect of the tools beeing at alpha, or will be not be able to debug silverlight when using firefox as the browser?

    Update: While I am using IE7 for debugging, how do i get it ti just run my silverlight projects and not give me a warning about scripts and ActiveX controls every time i try to run or debug my app?

    Update2: Figured out the "Blocked Content" warning but not until i had two identical html pages, one causing it and the other not and then noticing that one had DOS linefeeds and the other unix. Apparently IE7 considers unix linefeeds dangerous?

    Debugging silverlight not working in firefox is a bug in the alpha. It'll probably work if you do a manual attach:

    From the debug menu choose "Attach to process"

    Leave the transport as default, but change the "Attach to" to "Core Managed". The select firefox in the process list and you should be good to go.

    Thanks for info Sam. I'm fine with using IE for now. I was mostly curious whether this was a requirement of how Silverlight debugging works or just something not completed or debugged.

    Try these steps...

  • Type "about:config" into FF's address bar
  • Accept the warning (if applicable)
  • Search for the entry "dom.ipc.plugins.enabled.npctrl.dll"
  • Change its value from "true" to "false" (double-click)
  • Restart the browser

    That worked for me too -- thanks.  But (to echo my three-year-old son), "Why?"  Npctrl.dll is just a part of the Silverlight plugin, right?  Anybody know why disabling it is necessary/required/advisable?

    After changing

    dom.ipc.plugins.enabled.npctrl.dll value to false as reccomended exception

    System.AccessViolationException was unhandled
      Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
      InnerException:

    occurs always at line

    HtmlPage.Window.Navigate(sourceUri, "_blank",
                         "menubar=no,titlebar=no,status=no,toolbar=no,location=yes,width=" +
                        Int32.Parse(HtmlPage.Window.Eval("screen.width").ToString()) + ",height=" +
                            (Convert.ToInt32(HtmlPage.Window.Eval("screen.height")) - 20).ToString() );

    if this line is invoked by pressing Enter in listbox.

    How to fix this ?

    If dom.ipc.plugins.enabled.npctrl.dll if set to true exception does not occur.
