 +** C7XQ1: What is the difference between the way the CLR deals with unhandled exceptions in the .NET Framework 1.1 verses 2.0? **
 +
 +/* --== Question Answer separator ==-- */
 +
 +Answer: In 1.0, a backstop is provided for unhandled exceptions that occur on the following types of thread:
 +
 +  * A thread from the thread pool.
 +  * A thread created with the //Thread.Start// method.
 +  * A finaliser thread.
 +
 +In 2.0, these exceptions are left to proceed naturally.

 +
 +/* --== Question Answer separator ==-- */

 +
 +  * A //ThreadAbortException// thrown because of an //Abort// call.

 + 
 +Hint: The four //i//'s of duplication. 
 + 
 +Answer: 
 + 
 +  * //Imposed// - Developers feel they have no choice - the environment appears to require duplication. 
 +  * //Inadvertent// - Developers don't realise they are duplicating information. 
 +  * //Impatient// - Developers get lazy and duplicate because it seems easier.
