title: How to OpenWebConfiguration with physical path?
body: <p>I have a win form that creates a site in IIS7.
  One function needs to open the web.config file and make a few updates. (connection string, smtp, impersonation)</p>
  
  <p>However I do not have the virtual path, just the physical path.</p>
  
  <p>Is there any way I can still use WebConfigurationManager?</p>
  
  <p>I need to use it's ability to find section and read/write.</p>
  
  <pre><code>System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration
  </code></pre>
