+//      Major Version
+//      Minor Version 
+//      Build Number
+//      Revision
+//
+// You can specify all the values or you can default the Revision and Build Numbers

+//
+// In order to sign your assembly you must specify a key to use. Refer to the

+//
+// Use the attributes below to control which key is used for signing. 
+//
+// Notes: 
+//   (*) If no key is specified, the assembly is not signed.
+//   (*) KeyName refers to a key that has been installed in the Crypto Service
+//       Provider (CSP) on your machine. KeyFile refers to a file which contains
+//       a key.
+//   (*) If the KeyFile and the KeyName values are both specified, the 
+//       following processing occurs:
+//       (1) If the KeyName can be found in the CSP, that key is used.
+//       (2) If the KeyName does not exist and the KeyFile does exist, the key 
+//           in the KeyFile is installed into the CSP and used.
+//   (*) In order to create a KeyFile, you can use the sn.exe (Strong Name) utility.
+//       When specifying the KeyFile, the location of the KeyFile should be
+//       relative to the project output directory which is
+//       %Project Directory%\obj\<configuration>. For example, if your KeyFile is
+//       located in the project directory, you would specify the AssemblyKeyFile 
+//       attribute as [assembly: AssemblyKeyFile("..\\..\\mykey.snk")]

+// Smart thread pool in C#.
+// 7 Aug 2004 - Initial release
+// 14 Sep 2004 - Bug fixes 
+// 15 Oct 2004 - Added new features
+//        - Work items return result.
+//        - Support waiting synchronization for multiple work items.
+//        - Work items can be cancelled.
+//        - Passage of the caller thread’s context to the thread in the pool.
+//        - Minimal usage of WIN32 handles.
+//        - Minor bug fixes.
+// 26 Dec 2004 - Changes:
+//        - Removed static constructors.
+//      - Added finalizers.
+//        - Changed Exceptions so they are serializable.
+//        - Fixed the bug in one of the SmartThreadPool constructors.
+//        - Changed the SmartThreadPool.WaitAll() so it will support any number of waiters. 
+//        The SmartThreadPool.WaitAny() is still limited by the .NET Framework.
+//        - Added PostExecute with options on which cases to call it.
+//      - Added option to dispose of the state objects.
+//      - Added a WaitForIdle() method that waits until the work items queue is empty.
+//      - Added an STPStartInfo class for the initialization of the thread pool.
+//      - Changed exception handling so if a work item throws an exception it 
+//        is rethrown at GetResult(), rather then firing an UnhandledException event.
+//        Note that PostExecute exception are always ignored.
+// 25 Mar 2005 - Changes:
+//        - Fixed lost of work items bug
+// 3 Jul 2005: Changes.
+//      - Fixed bug where Enqueue() throws an exception because PopWaiter() returned null, hardly reconstructed. 
+// 16 Aug 2005: Changes.
+//        - Fixed bug where the InUseThreads becomes negative when canceling work items. 
+//
+// 31 Jan 2006 - Changes:
+//        - Added work items priority
+//        - Removed support of chained delegates in callbacks and post executes (nobody really use this)
+//        - Added work items groups
+//        - Added work items groups idle event
+//        - Changed SmartThreadPool.WaitAll() behavior so when it gets empty array
+//          it returns true rather then throwing an exception.
+//        - Added option to start the STP and the WIG as suspended
+//        - Exception behavior changed, the real exception is returned by an 
+//          inner exception
+//        - Added option to keep the Http context of the caller thread. (Thanks to Steven T.)
+//        - Added performance counters
+//        - Added priority to the threads in the pool
+//
+// 13 Feb 2006 - Changes:
+//        - Added a call to the dispose of the Performance Counter so
+//          their won't be a Performance Counter leak.
+//        - Added exception catch in case the Performance Counters cannot 
+//          be created.
