This does not happen if you throw a new exception that wraps the original one, so this option is the one that guarantees that no information is lost.</p> <p>Of course most of the times the fact that &quot;throw;&quot; maintains the full stacktrace is sufficient, but nonetheless is something to keep in mind.</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10350116" width="1" height="1">
