WebConfigAddApplicationSettings.config

FIRST ADD the applicaton settings section group

<configSections>
    <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
        <section name="Tools.Instrumentation.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    </sectionGroup>
</configSections>

Then you can copy the complete applicationSettings section into the Web Config as long as the section name matches. In above
example, Tools.Instrumentation.Propertis.Settings

<applicationSettings>
        <Tools.Instrumentation.Properties.Settings>
            <setting name="LogLevel" serializeAs="String">
                <value>DEBUG</value>
            </setting>
            <setting name="AppName" serializeAs="String">
                <value>MyApp</value>
            </setting>
            <setting name="Port" serializeAs="String">
                <!--value>33333</value-->
                <value>0</value>
            </setting>
        </Tools.Instrumentation.Properties.Settings>
    </configuration>
