You need to configure IIS to treat XAP as static content. Try this:

<configuration>
   <system.webServer>
    <staticContent>
      <mimeMap fileExtension=".xaml" mimeType="application/xaml+xml" />
      <mimeMap fileExtension=".xap" mimeType="application/x-silverlight-app" />
      <mimeMap fileExtension=".xbap" mimeType="application/x-ms-xbap" />
    </staticContent>
   </system.webServer>
</configuration>
