Answer 1

I believe you’re going to need to host this page on a website. See the relevant information here and here.

The second issues is one of hosting Silverlight applications (XAPs) on your site that are from a different domain. What I mean here is that your site (www.coolwebapp.com) has an tag for Silverlight plugin that has the Source parameter set to apps.anothersite.com/foo.xap. This is essentially the cross-domain hosting situation. What happens in this situation is that the plugin loads but the app does not, presenting in just a big blank space where the app should be.

Since the app loads fine when I host it on a site I would assume you’re hitting some kind of cross-domain error going from file:// to http://

I was also able to just download the xap file referenced in the object tag and then put that file in the same directory as the html page and it worked.

<param name="source"value="RCSRemote.xap" /> 

So you can try that as well.
