// Description: DeploymentExceptionMapper class definition. 
// 
// History:
//  2005/02/08 : [....] - Created 
//  2005/08/22 : [....] - Added boot WinFX functionality
//  2007/08/01 : [....]  - Added detection of System.Core.dll to infer required platform version.
//                          Because WPF v3.5 still has WindowsBase v3.0.0.0, the original heuristic failed.
