Hi,
Q1: Do the section handlers in .NET work with CMAB? The CMAB seems to
say so, but I am not sure.
Q2: I am having trouble using CMAB with the standard section handler -
I've been able to use CMAB with the HashtableSectio nHandler. However,
when I try to replace this with DictionarySecti onHandler, I get a null
reference exception:
See below for App.config file and the referenced config file.
Unhandled Exception: System.TypeInit ializationExcep tion: The type
initializer for "LNUK.Framework .Co
mmon.DBWrapper" threw an exception. --->
