title: File Permissions Issue with Silverlight
body: <p>I have a Silverlight 4 / C# project I'm working on in Visual Studio. I made an XML data file by right clicking on the project >> Add New Item >> Xml File. I then try to open the file:</p>
  
  <pre><code>        StreamReader streamReader = new StreamReader("data.xml");
  </code></pre>
  
  <p>However, this gives a security exception. How can I get around this, or grant the necessary permissions?</p>
