Hi,

I am developing a middle tier WCF server called BusinessLogic, using the
Enterprise Library. Although I posted similar question on the EL forums (no
answer yet), it seems to me that the problem is more general .NET related
than WCF or EL specific. The problem shows when EL exception handling block
catches one exception and according to a policy throws different exception:
FaultException<SomeFaultFromBusinessLogic>. When the app. block tries to load
the fault class from BusinessLogic.dll it throws an exception saying that it
cannot find BusinessLogic ver. 1.0.0.2719 but the funny thing is that my
assembly is 1.0.0.1234. No matter what version is the assembly it always
tries to load ver. 1.0.0.2719. Can you please help - this has been haunting
me for weeks now.

Thank you
Val

A first chance exception of type 'Abc.BusinessLogic.FieldNullException'
occurred in BusinessLogic.dll
