Exception handling in .NET Framework 4.0

Question

Explain how exception handling is changed in the .NET Framework 4.0?

Answer 1

In .NET 4.0, a new namespace, System.Runtime.ExceptionServices, has been introduced which comprises of the following classes in order to handle exceptions in a better and advanced manner:

a)HandleProcessCorruptedStateExceptionsAttribute Class - Allows managed code to handle the corrupted state exceptions which may occur in an operating system. Such type of the exceptions cannot be caught by using the try...catch block.  In order to handle such exceptions, you can apply this attribute within the method which is assigned to handle such exceptions.

b)FirstChanceExceptionEventArgs Class – It generates an event when a managed exception first arises in your code, before the common language runtime begins searching for an event handlers.
