I have some .NET 2.0 c# code that reads data from an XML file, and imports it
into CRM.  The code works fine until I throw an 18MB file at it.  My code
will process a large portion of the file, but then stop & display an error
message.  I added the following code to my web.config, but with no success:

<system.web>
 <httpRuntime
   executionTimeout="3600"  
   maxRequestLength="102400"
 />
</system.web>

Here’s the detailed error massage.  Thanks for looking at it.
