ApplicationSettings for DLL with WCF and Console Application - dll

Question

My project consists of a web service (WCF) and a console application that uses a common library in other projects.
This library has ApplicationSettings.
With Console application, I only have to set:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
<section name="MyProject.Library.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</sectionGroup>
</configSections>
[...]
<applicationSettings>
<MyProject.Library.Properties.Settings>
<setting name="EnvironmentMask" serializeAs="String">
<value>RCT_</value>
</setting>
</MyProject.Library.Properties.Settings>
</applicationSettings>
[...]
</configuration>
I tried to do the same side Web.config
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<sectionGroup name="MyCompany.ConfigurationGroup">
<section name="SignedFileConfiguration" type="MyCompany.Web.SecureFileProxy.SignedFileConfigurationHandler, Net.MyCompany.Web" />
</sectionGroup>
<sectionGroup name="applicationSettings">
<section name="MyProject.Library.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</sectionGroup>
</configSections>
[...]
<MyCompany.ConfigurationGroup>
<SignedFileConfiguration Secret="SecretKey!" PatternOfGeneratedUrl="http://www.myCompany.net/cgi/getFile.aspx?volume={0}&path={1}&token={2}&name={3}" ConfiguratorType="MyCompany.Web.SecureFileProxy.SignedFileConfiguration, Net.MyCompany.Web">
<Volumes>
<add Name="fallow" PhysicalPath="" />
</Volumes>
</SignedFileConfiguration>
</MyCompany.ConfigurationGroup>
<applicationSettings>
<MyProject.Library.Properties.Settings>
<setting name="EnvironmentMask" serializeAs="String">
<value>DEV_</value>
</setting>
</MyProject.Library.Properties.Settings>
</applicationSettings>
[...]
</configuration>
During the execution of the web service, I get an exception : System.Configuration.SettingsPropertyNotFoundException and the object MyProject.Library.Properties.Settings is empty
the only website which talk about that is https://littletalk.wordpress.com/2008/05/07/use-applicationsettings-in-web-application/ but it isn't enought for me.
I hope you could help me.
Thanks for your attention

I found the cause of this issue.
it's because I use log4net and it has an issue https://issues.apache.org/jira/browse/LOG4NET-398
I have to find a new way to do it.
