Why is this statement not valid?

List<Exception> list = new List<ApplicationException>();

As far as ApplicationException is a Exception descendant all operations, available with List are available with List.

So, what's the design reason to deny such a behavior?

Add the next line - `list.Add(new NotAnApplicationException());` - and ponder what your `List`, that was told it would contain `ApplicationException` objects, is going to do. – Damien_The_Unbeliever Oct 19 '15 at 07:55
I never tried like this, but why do you need a list of exceptions? – Amit Kumar Ghosh Oct 19 '15 at 07:55

@Damien_The_Unbeliever, thanks a lot. Never thought in such a way. – brutallord Oct 19 '15 at 08:02
