title: .NET Exception error, what does this error means?
body: <p>I've tried to develop a simple winform utility which is using xml file as its database. I've used VS 2008 express edition, C#.</p>
  
  <p>When this utility tries to write into the xml file then this error is displayed on other computer. I've tried to provide System.Xml.dll &amp; System.Xml.Linq.dll in the same folder on the other computer but no use.</p>
  
  <p>What does it means? Any solution?</p>
  
  <pre><code>See the end of this message for details on invoking 
  just-in-time (JIT) debugging instead of this dialog box.

  ************** JIT Debugging **************
  To enable just-in-time (JIT) debugging, the .config file for this
  application or computer (machine.config) must have the
  jitDebugging value set in the system.windows.forms section.
  The application must also be compiled with debugging
  enabled.
  
  For example:
  
  &lt;configuration&gt;
      &lt;system.windows.forms jitDebugging="true" /&gt;
  &lt;/configuration&gt;
  
  When JIT debugging is enabled, any unhandled exception
  will be sent to the JIT debugger registered on the computer
  rather than be handled by this dialog box.
