Unable To Add Value To Custom App.Config Section

I am absolutely at my wits end with this, having tried basically everything. I also do not see any existing stackoverflow threads about doing this.
I have an app.config file for my C# project, and it stores a list of servers which the user can create and add to.
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="servers" type="System.Configuration.AppSettingsSection" />
</configSections>
<servers>
<add key="server" value="678,true,true"/>
</servers>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.8"/>
</startup>
<appSettings>
<add key="nightmode" value="Dark"/>
<add key="theme" value="Red"/>
</appSettings>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="ControlzEx" publicKeyToken="69f1c32f803d307e" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.0.0.0"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
((NameValueCollection)ConfigurationManager.GetSection("servers")).Add("server", $"{port}," + $"{ (dialogResult1 == MessageDialogResult.Affirmative) },{dialogResult2 == MessageDialogResult.Affirmative}");
When the user goes to add a new key the the "servers" section, it throws the below exception.
System.Configuration.ConfigurationErrorsException: 'The configuration is read only.'
I am bewildered why this is happening

you can try:
Configuration config = System.Configuration.ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.AppSettings.Settings.Add("test", "propertyValue");
config.Save(ConfigurationSaveMode.Modified, true);
System.Configuration.ConfigurationManager.RefreshSection("appSettings");
string test = ConfigurationManager.AppSettings["test"];
This get de appsettings section values.
Ps.: You need Install-Package System.Configuration.ConfigurationManager.

I ended up generating my own XML configuration, since that appears to be the best way to do things.

How to retrieve a custom section from an app.config in .NET?

I have a .NET Framework 4.7.2 library project, inside there's an App.config file like this:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="NewDocumentMetadata" type="System.Configuration.NameValueSectionHandler" />
</configSections>
<NewDocumentMetadata>
<add key="Type" value="principal"/>
<add key="IsActive" value="true"/>
</NewDocumentMetadata>
<appSettings>
<add key="Entity" value="9"/>
<add key="Flux" value="pdf"/>
</appSettings>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<!-- [...] -->
</assemblyBinding>
</runtime>
</configuration>
As you can see, I have some standard settings, but also a custom section. I have no problems with the settings, but when I retrieve the section, it works, but there I'm stuck, when I try to cast it to NameValueCollection or AppSettingsSection it gives me a null value, I'm stuck with a ConfigurationOption object I am not able to work with.
var appConfig = ConfigurationManager.OpenExeConfiguration(Assembly.GetExecutingAssembly().Location);
flux = appConfig.AppSettings.Settings["Flux"].Value; //Works
entity = appConfig.AppSettings.Settings["Entity"].Value; //Works
var metadataSection = appConfig.GetSection("NewDocumentMetadata"); //What do I do with this boy?
I need to retrieve the settings within the NewDocumentMetadata section, how to proceed?

You should try this :
var metadataSection = ConfigurationManager.GetSection("NewDocumentMetadata") as NameValueCollection;
// Get all the value foreach key
foreach(var key in metadataSection.AllKeys)
{
string value = metadataSection.GetValues(key).FirstOrDefault()
}

I just found out that the problem was with this line :
<section name="NewDocumentMetadata" type="System.Configuration.NameValueSectionHandler" />.
I changed the type and went for this :
<section name="NewDocumentMetadata" type="System.Configuration.AppSettingsSection, System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
Now I just have to do this kind of code to retrieve the values I want :
var metadataSection = (AppSettingsSection)appConfig.GetSection("NewDocumentMetadata");
foreach (var key in metadataSection.Settings.AllKeys)
{
string value = metadataSection.Settings[key].Value;
}

How to stop NHibernate from logging in Azure

I created an Azure web job project that uses Fluent NHibernate for its ORM. The program itself works fine and does what it's supposed to. However, after publishing the web job and running it live, every single SQL statement that NHibernate generates is output to the log, and I don't want this.
I thought that NHibernate by default does not output SQL statements, and I would have to enable it explicitly. However, it seems to be happening automatically, and I can't seem to turn it off. Is there some setting somewhere that I need to set to stop this logging?
This is my configuration, my app.config, and an example database query:
NHibernate configuration
public static ISessionFactory CreateSessionFactory()
{
string connString = ConnectionStringHelper.ConnectionString;
return Fluently.Configure()
.Database(MsSqlConfiguration.MsSql2008
.ConnectionString(connString)
)
.Cache(c => c
.UseQueryCache())
.Mappings(m => m.FluentMappings.AddFromAssemblyOf<Functions>())
.BuildSessionFactory();
}
App config
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<connectionStrings>
<add name="AzureWebJobsDashboard" connectionString="DefaultEndpointsProtocol=https;AccountName=***;AccountKey=***" />
<add name="AzureWebJobsStorage" connectionString="DefaultEndpointsProtocol=https;AccountName=***;AccountKey=***" />

Sample DB Query
using (ISessionFactory sessionFactory = CreateSessionFactory())
{
using (var session = sessionFactory.OpenSession())
{
var accountCrit = session.CreateCriteria<AccountRec>();
accountCrit.Add(Expression.Eq("AccountId", batch.AccountId));
var accounts = accountCrit.List<AccountRec>();
}
}
The above statement generates this in the Azure logs:
[09/06/2017 03:57:30 > 442002: INFO] NHibernate: SELECT this_.AccountId as AccountId9418_0_, this_.RingCentralId as RingCent2_9418_0_, this_.RingCentralExtension as RingCent3_9418_0_ FROM T_ACCOUNT this_ WHERE this_.AccountId = #p0;#p0 = '253' [Type: Int]
But I don't want it to generate that in the logs.

I'm guessing that somehow, Azure is enabling log4net and NHibernate is then able to broadcast its logging.
Try adding these blocks to your config and see what effect it has:
<configSections>
<section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
</configSections>
<log4net debug="false">
<appender name="WindowsDebugOutput" type="log4net.Appender.DebugAppender, log4net">
<layout type="log4net.Layout.PatternLayout,log4net">
<param name="ConversionPattern" value="%d{ABSOLUTE} %-5p %c{1}:%L - %m%n" />
</layout>
</appender>
<logger name="NHibernate.SQL" additivity="false">
<level value="OFF" />
<appender-ref ref="WindowsDebugOutput" />
</logger>
</log4net>
You might need to tweak the appender but the key is the OFF value in the logger.level. You might be able to set this at a higher, global level too. However, my knowledge of how to configure log4net is lacking.

Configsource path using wrongly

I'm trying to use a config file by directing there from App.config.
I have created a folder named Config inside my solution and created a new config file named Environment.config.
My App.Config looks as following:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
</configSections>
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
<providers>
<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
</entityFramework>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /></startup>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
<appSettings configSource="Config/Environment.config"/>
</configuration>
and the Environment.config looks as the following:
<appSettings>
<add key="URL" value="http://foo.aspx"/>
</appSettings>
I'm getting an error which says:
Result Message:
OneTimeSetUp: System.Configuration.ConfigurationErrorsException : Configuration system failed to initialize
----> System.Configuration.ConfigurationErrorsException : The configSource attribute must be a relative physical path, so the '/' character is not allowed. (D:\tfs\QA - Automation\Projects\ReportAppeal\ReportAppeal\bin\Debug\ReportAppeal.dll.config line 22)
I have tried to switch from "/" to "\" but got a different error.
Result Message:
System.Configuration.ConfigurationErrorsException : Unable to open configSource file 'Config\Environment.config'. (D:\tfs\QA - Automation\Projects\ReportAppeal\ReportAppeal\bin\Debug\ReportAppeal.dll.config line 22)
TearDown : System.NullReferenceException : Object reference not set to an instance of an object.
I'll probably need to change the way I'm directing the Environment.config file but I'm not sure how.

As the error says:
The configSource attribute must be a relative physical path
So you will need to change your key to a physical path, not a relative one:
<appSettings configSource="C:\Config\Environment.config"/>
Or just leave it under the root:
<appSettings configSource="Environment.config"/>

NLog is not reading my app.config settings in a Console application

I am trying to do a little spike and I cannot get log file generated.
This is my NLog configuration:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="nlog" type="NLog.Config.ConfigSectionHandler, NLog" />
</configSections>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
</startup>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Npgsql" publicKeyToken="5d8b90d52f46fda7" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-3.2.4.0" newVersion="3.2.4.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
<nlog throwExceptions="true"
internalLogLevel="Warning"
internalLogFile="Rebus.Tests.Output.NLog.Internal.log"
internalLogToConsole="true"
xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<targets>
<target name="normalLogfile" type="File" fileName="${basedir}/Rebus.Tests.Output.log" />
<target name="normalConsole" type="Console" detectConsoleAvailable="true" />
</targets>
<rules>
<logger name="NormalLog" minlevel="Trace" writeTo="normalLogfile, normalConsole" />
</rules>
</nlog>
</configuration>
And here is my static Main in the Console Application:
var logger = LogManager.GetLogger("NormalLog");
logger.Error("This is a log error line");
But nothing is logged neither LogFile nor Console.
The application.exe.config is in the bin/Debug runtime folder.
And I am looking for the log file with SearchEverything so it will found in any folder where it is.
Adding some information to this question if I put a breakpoint to inspect logger variable I can see no configuration was read:

Try to change
var logger = LogManager.GetLogger("NormalLog");
to
var logger = LogManager.GetLogger("normalLogfile");
because as far as I know you have to get the logger via target-name and not via rule-name.
//edit
Have you tried to remove the nlog attributes in you app.config? Just to be sure none of them is the problem.
