Hi there,

 thanks for your valuable time for reading my problem.

I have n-tier architecture:  a.  Presentation Layer

                                          b. Business Layer:    (i) BusinessLogic (ii) BusinessEntities

                                          c. DataLayer

                                         d.  ServiceLayer (WCF)

I want to implement Exception, Caching, Logging using Enterprise Library 5.0.

Please guide me how to proceed.I will be highly obliged if i can get the demo architecture or some help at your convenience.!!!
