Thanks for the suggestion. I simplified the example in hopes of not boring readers with details.

Our current architecture currently uses MVP pattern for the UI layer. The presenters make use of a Business Service Client Adapter assembly that provides data from our Business Service layer through WCF.

The heart of my question really has to do with cross cutting concerns like Logging, Exception Handling, Validation, Instrumentation etc. We are implementing the use of MS Application Blocks.

If the cross cutting concerns are encapsulated in accessor classes within the Common assembly. How do you handle cross cutting concerns that require database access?

Should they have their own encapsulated DAL making them like a standalone service?

If they try to use the existing Business Logic layer (and DAL) this will create a circular reference.

A concrete example could be Validation, where the validation error messages must be localized and loaded from a database.
