title: How can I add a ClientAccessPolicy.xml file to the SharePoint 2010 root folder?
body: <p>In a Visual Studio 2010 SharePoint (2010) project, we can add mapped SharePoint folders, including the {SharePointRoot} folder. When I deploy my project, I can see that the root files end up in the 14-hive, but they never appear in the web site root.</p>
  
  <p>What I really want to accomplish to unit test my Silverlight application which communicates with a SharePoint site. I have tried many variations on the subject, from adding MS unit tests to common class library project, test projects, and finally a Silverlight test project.</p>
  
  <p>When I run my Silverlight test project, all tests that access the SharePoint site fails due to a missing ClientAccessPolicy.xml. I really don't want this file in the SharePoint site, as we don't want to grant access to outside Silverlight apps.</p>
