How has my stack trace got file system references to the build machine?
<p>I use svn and asp.net. We have a website and there is an error in it. Im not really concerned about the error I know how to fix it what im wondering is how .net is showing the original file path that the .cs files were in when the prioject was built:</p>

<pre><code>[SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.]

</code></pre>

<p>I mean this is a pre-compiled asp.net application so why are the references in it?</p>
