CMAB and standard section handlers

[R. Raghuraman]

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 HashtableSectionHandler. However,
when I try to replace this with DictionarySectionHandler, I get a null
reference exception:

See below for App.config file and the referenced config file.
Unhandled Exception: System.TypeInitializationException: The type
initializer for "LNUK.Framework.Co
mmon.DBWrapper" threw an exception. --->
System.NullReferenceException: Object reference not set to
an instance of an object.

This is my app.config file

<configuration>
<configSections>
<section name="applicationConfigurationManagement"
type="Microsoft.ApplicationBlocks.ConfigurationMan agement.ConfigurationManagerSectionHandler,Microso ft.ApplicationBlocks.ConfigurationManagement,
Version=1.0.0.0,Culture=neutral,PublicKeyToken=nul l" />

</configSections>
<appSettings>
<add key="log4net.Config"
value="C:\Raghu\Codebase\DatabaseWrapper\log4net.c onfig"></add>

</appSettings>

<applicationConfigurationManagement defaultSection="DBConfigSection">
<configSection name="DBConfigSection">

type="Microsoft.ApplicationBlocks.ConfigurationMan agement.Storage.XmlFileStorage"
path="..\..\Config\Database.config"
signed="false"
encrypted="false" />
</configSection>
</applicationConfigurationManagement>
</configuration>

This is my Database.config file referred above

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<DBConfigSection>
<add key="ConnectString" value="Persist Security

<add key="RetryCount" value="3"></add>
<add key="CommandTimeout" value="30"></add>
</DBConfigSection>
</configuration>

It works but you need to tweak it a little bit.

Please see the following bug report:
