title: How to use +number in asp.net server error page?
body: <p>If my app throws an exception I see the server error page. The stack track shows the method where the error occurred (null reference exception for example), and a plus number, like +730. How can I backtrack that number to the line of c# code?</p>
  
  <p>Edit: I don't know what "+730" represents and I don't have a reference manual for it. One thing I can tell you is that this is not a line in a C# file.</p>
