Yes I did. These are the settings:

<OutOfBrowserSettings ShortName="SL4Com Application" EnableGPUAcceleration="True" ShowInstallMenuItem="True">
  <OutOfBrowserSettings.Blurb>SL4Com Application on your desktop; at home, at work or on the go.</OutOfBrowserSettings.Blurb>
  <OutOfBrowserSettings.WindowSettings>
    <WindowSettings Title="SL4Com Application" />
  </OutOfBrowserSettings.WindowSettings>
  <OutOfBrowserSettings.SecuritySettings>
    <SecuritySettings ElevatedPermissions="Required" />
  </OutOfBrowserSettings.SecuritySettings>
  <OutOfBrowserSettings.Icons />
</OutOfBrowserSettings>

Craig mentioned this and that was the reason. Once I changed the path to c:\temp the sample worked.

Basically i want to be able to read an XML file either on disk or passed to a method from a web service.

The reason is I am looking at implementing this control:
http://silverlightcoverflow.codeplex.com/
into a Silverlight OOB app.

The sample shows getting the data from the Apple website, and using a web service to download the images. But I want to be able to point the app to any folder on my local hard disk (or remote storage for that matter), with images, and it will then read in the list of images in that folder and generate the XMl and feed it to the control in the XML format required by the app.

Most similar code I found use a hard coded array pre filled or access a web service and is not generic enough for my needs.

Since I have only just recently started looking at Silverlight, this is beyond me, so was looking for some sample code to do what I want.

Thanks
