Hosting Silverlight widget from local file system
I'm trying to host a remote Silverlight widget in an html file that will exist locally on the hard drive, but whenever I open the html file, the Silverlight content does not show up.  If I move the file to a web server and then access it through http, it works perfectly.  I figured out (or at least I assume) that the widget is trying to make a call back to the web server but it's failing because of the [cross zone restrictions][1] in SL 2+.  I've also seen a few reports from users talking about running into this issue when debugging from a local file.  My question is, how can I tell for sure that this is the issue going on/what tools might I use to verify my hypothesis?

Additionally, (knowing full well that there are elevation of privileges security concerns to take into account) is there any way that I could declare the web services the widget calls as safe (for instance adding to the trusted sites) in such a way that Silverlight would be able to perform the calls without the security exceptions?

An example of a widget I'm talking about is below:

    <object type="application/x-silverlight-2" data="data:application/x-silverlight-2," width="400" height="400"><param name="minRuntimeVersion" value="3.0.40624.0" /><param name="background" value="#141414" /><param name="splashScreenSource" value="http://memorabilia.hardrock.com/Widget/3.2009.1014.0/Splash.xaml" /><param name="source" value="http://memorabilia.hardrock.com/Widget/3.2009.1014.0/HardRock.Memorabilia.Silverlight.Widget.xap" /><param name="enableHtmlAccess" value="true" /><param name="initParams" value="item=034739" /><a href="http://go.microsoft.com/fwlink/?linkid=149156&v=3.0.40624.0"><img src="http://memorabilia.hardrock.com/Widget/3.2009.1014.0/Ping.gif?type=install&item=034739" style="background:#141414 url(http://content.memorabilia.hardrock.com/Assets/Images/widget/034739.jpg) no-repeat center;margin:0;padding:0;border:0;" width="400" height="400" /></a></object>
