log4net not working on other machines - vb.net

I created a web service project that uses Log4Net to log to the event viewer and optionally to a .log file. Everything works great on my machine, when I try to deploy it on another machine it won't even log to the text file or the event viewer. The fact that it's not even writing to the text file makes me think it's not able to find the log4net.dll or something to that effect?
I'm also receiving an error message when it hits the noted line below in my global.asax:
log4net:ERROR XmlConfigurator: Failed to find configuration section 'log4net' in the application's .config file. Check your .config file for the and elements. The configuration section should look like:
section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /
I'm stumped, I have no idea why this isn't working, help!
Ran an exe compiled from the following code that adds the source to the eventlog in Windows, like I said, works fine on my machine:
Option Explicit On
Option Strict On
Imports System
Imports System.Diagnostics
Imports System.Threading
Module Module1
Sub Main()
If Not EventLog.SourceExists("LendingService") Then
EventLog.CreateEventSource("LendingService", "Application")
Console.WriteLine("Creating Event Source: LendingService")
Else
Console.WriteLine("LendingService events already defined to this system.")
End If
End Sub
End Module

You are looking for you configuration in your app.config file. To change this you can use:
// Configure log4net using the .log4net file
[assembly: log4net.Config.XmlConfigurator(ConfigFileExtension="log4net",Watch=true)]
// This will cause log4net to look for a configuration file
// called TestApp.exe.log4net in the application base
// directory (i.e. the directory containing TestApp.exe)
// The config file will be watched for changes.
or
log4net.Config.XmlConfigurator(ConfigFileExtension="log4net",Watch=true)]
as reference:
// Configure log4net using the .config file
[assembly: log4net.Config.XmlConfigurator(Watch=true)]
// This will cause log4net to look for a configuration file

VB My.Settings Configuration Error Exception

I am creating a form where I want to save a list of values to My.Settings. In the form, changes will be made to the list and when I close the form, the updated list will be saved to the settings. The next time I start the form my list will get the values from My.Settings.
This is what I have done so far.
To load the list from the settings:
Dim fl As New List(Of String)
For Each Item As String In My.Settings.foodlist
fl.Add(Item)
Next
And then to save the list into settings on closing the form:
My.Settings.foodlist.Clear()
For Each Item As String In fl
My.Settings.foodlist.Add(Item)
Next
My.Settings.Save()
Form1.Close()
In my project settings, I have defined foodlist as a system.collection.specialized.stringcollection. The scope is set to user, and the value is currently blank.
However, when I run, I receive an error which says System.Configuration.ConfigurationErrorsException: 'Configuration system failed to initialize'
ConfigurationErrorsException: Unrecognized configuration section system.diagnostics. (C:\Users\samsj\Downloads\EatWhat_webversion\WinFormsApp_22Feb\bin\Debug\net6.0-windows\EatWhat_webver.dll.config line 5)
In particular, the line that seems to have an issue is
Return CType(Me("foodlist"), Global.System.Collections.Specialized.StringCollection)
What am I doing wrong?
I managed to solve this after looking through suggestions from another forum. I went to my dll.config file and deleted the entire system.diagnostics code:
<system.diagnostics>
<sources>
<!-- This section defines the logging configuration for My.Application.Log -->
<source name="DefaultSource" switchName="DefaultSwitch">
<listeners>
<add name="FileLog"/>
<!-- Uncomment the below section to write to the Application Event Log -->
<!--<add name="EventLog"/>-->
</listeners>
</source>
</sources>
<switches>
<add name="DefaultSwitch" value="Information" />
</switches>
<sharedListeners>
<add name="FileLog"

initializeData="FileLogWriter"/>
<!-- Uncomment the below section and replace APPLICATION_NAME with the name of your application to write to the Application Event Log -->
<!--<add name="EventLog" type="System.Diagnostics.EventLogTraceListener" initializeData="APPLICATION_NAME"/> -->
</sharedListeners>
</system.diagnostics>
I have absolutely no idea why deleting this code works, since I assumed that this is a default code.

Connection string error between projects with EF

My solution exits out of 3 Projects:
SP_Class_Library contains my EF model
SP_Control_Library is a class library that contains all my custom and
user controls
SP_EF_TEST is my Form Application
I created a custom control cc_User_DropDown with the following code
Protected Overrides Sub OnCreateControl()
MyBase.OnCreateControl()
LoadUsers()
End Sub
Private Sub LoadUsers()
Dim UserList As List(Of SP_User) = Nothing
UserList = (From c In ent.SP_User
Where c.usr_Active = True
Select c
Order By c.usr_Name).ToList
Dim blank As New SP_User
blank.usr_ID = 0
blank.usr_Name = "Please select a user..."
UserList.Insert(0, blank)
Me.DisplayMember = "usr_Name"
Me.ValueMember = "usr_ID"
Me.DataSource = UserList
End Sub
The problem comes when I try and add the custom control to either u_Users or Form1 I get the error:
If I comment the code and build I can add the control, but as soon as I uncomment the code and build I get the following:
I have tried suggestions that say I must add the app.config to all the projects, Copy the connectionstring to all the .config files and remove the .config file from the dll and add it to the Form Application but it does not work.

Initialized GetLogger at the top of the Service class as follows
Private Shared ReadOnly log As ILog = LogManager.GetLogger(GetType(Service))
I have created GlobalContext property for LogName as follows
log4net.GlobalContext.Properties("LogName") = ConfigurationManager.AppSettings("LogPath") & "Service." & Format(Now, "ddMMyyyy") & ".txt"
Logging is done with log.Info as follows
log.Info(strComments)
In this scenario, the log file is created as "null" under Project folder and logging the details.
I want the log location to be "D:\Service\Service.30082012.txt" according to the code above.
What am I missing? Please help me out.
Typically I separate the log4net configuration from my web.config to avoid web application restarts ( How to prevent an ASP.NET application restarting when the web.config is modified? ) when you change the web.config file.
I usually just have a log4net.config file to store all of these settings and I configure it to watch the config file for changes:
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]
Also I'm not quite sure why you are storing your log file directory outside of the log4net configuration unless it's just easier for you to modify. I typically keep the path in the log4net config like so:
<appender name="File" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="${ALLUSERSPROFILE}/CompanyName/Logs/ApplicationName/%date{MM-dd-yyyy} - Whatever.log" />
Make sure you don't have any log commands before you set the LogName property.
Also check that logname is being set correctly ie, check that
ConfigurationManager.AppSettings("LogPath") & "Service." & Format(Now, "ddMMyyyy") & ".txt"
is not evalulating to null

Why is IsInfoEnabled false? log4net

I have log4net implemented in a Visual Studio 2010 VB.NET Windows service. It used to work, but not anymore.
I have a sub RunTasks that gets started by the service every minute.
When I debug this procedure using a console project in the same solution, the logging works. However when I install the service and run it, and debug it using VS by attaching to the process, I found out that IsInfoEnabled, IsDebugEnabled, IsErrorEnabled etc. are all set to false, and I guess that's why the logging is not working, although RunTasks is executed by the service.
I have the following class, if I understand things right the XMLConfigurator is started before GetLogger.
Imports System.Reflection
<Assembly: log4net.Config.XMLConfigurator(ConfigFile:="LogConfig.xml", Watch:=True)>
Public NotInheritable Class Logging
Private Shared _LogName As String
Private Shared _ilog As log4net.ILog
Private Sub New()
End Sub
Public Shared ReadOnly Property ILog() As log4net.ILog
Get
If _ilog Is Nothing Then
_ilog = log4net.LogManager.GetLogger(LogName)
End If
Return _ilog
End Get
End Property
Private Shared ReadOnly Property LogName() As String
Get
If _LogName = "" Then
'If GetType(MySettings).GetProperty("LogName") IsNot Nothing Then
' _LogName = GetType(MySettings).GetProperty("LogName").GetValue(MySettings.Default, Nothing)
'End If
If _LogName = "" Then _LogName = "DefaultLogger"
End If
Return _LogName
End Get
End Property
End Class
The logging itself looks like this:
ILog.Info("Starting RunTasks ... ")
And here is my LogConfig.xml
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<log4net>
<appender name="textfileAppender" type="log4net.Appender.RollingFileAppender">
<file value="myLogFile.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="3" />
<maximumFileSize value="100KB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date{yyyy-MM-dd HH:mm:ss} %-5level - %message%newline" />
</layout>
</appender>
<logger name="DefaultLogger">
<level value="ALL" />
<appender-ref ref="textfileAppender" />
</logger>
</log4net>
</configuration>
I found the answer myself, I had to move the following line of code:
<Assembly: log4net.Config.XMLConfigurator(ConfigFile:="LogConfig.xml", Watch:=True)>
... (see first code block above) to the AssemblyInfo.vb of the solutions startup project. XMLConfigurator has to be executed before GetLogger is.

WCF - One OperationContract sees Web.config, another doesn't

I have a WCF service with two methods, Ping and PutAddress. Ping works fine, but PutAddress was failing to initialize NHibernate correctly. Narrowing down the issue, I realized that the relevant settings from Web.config were not being read by PutAddress.
Strangely, Ping does have access to the settings from Web.config. I removed all of the NHibernate code and boiled it down to just trying to read the settings. Ping is able to read the settings (returns non-null, values in result are correct) while PutAddress' result is null.
Again, NHibernate is now completely out of the picture. Both methods simply try to read the relevant settings from Web.config. Ping succeeds while PutAddress fails.
Any thoughts?
Interface:
[ServiceContract]
public interface IMyService
{
[OperationContract]
string Ping();
[OperationContract]
Address PutAddress(Address address);
}
Implementation:
public class MyService : IMyService
{
public string Ping()
{
NHibernate.Cfg.ConfigurationSchema.HibernateConfiguration result =
(NHibernate.Cfg.ConfigurationSchema.HibernateConfiguration)
System.Configuration.ConfigurationManager.GetSection("hibernate-configuration");
if (result == null)
{
System.Diagnostics.Debugger.Break(); // Does NOT break, "Pong" returned
}
return "Pong";
}
public Address PutAddress(Address address)
{
NHibernate.Cfg.ConfigurationSchema.HibernateConfiguration result =
(NHibernate.Cfg.ConfigurationSchema.HibernateConfiguration)
System.Configuration.ConfigurationManager.GetSection("hibernate-configuration");
if (result == null)
{
System.Diagnostics.Debugger.Break(); // Breaks, result is null
}
return address; // Return version potentially modified with DB-assigned ID
}
}

Found the problem - one call was from a Unit Test that I hand-coded, which uses MyServiceClient that was generated by Visual Studio when I added a Service Reference. The other call was from a unit test that was created by the Visual Studio (2010) Unit Test wizard, which just instantiated MyService as an object. The VS-generated unit test was running in-process as a result.
I had an odd problem myself. I could not return "DataTable" objects from a WCF operation. I wonder if there could be a problem with returning an "Address" object from a WCF operation as well.
I don't know the complete answer to your question, but I would suggest the following
In your code for PutAddress, try replacing Address PutAddress(Address address); with string PutAddress(Address address); and replace return address; with return "Pong"
By doing so, you will ascertain the flow of execution through your code. Make sure that you are actually breaking and returning null as opposed to returning a null value of address.
If the new code returns null, then you are in fact having trouble reading from the file. I suspect that it will actually return "Pong", indicating that your code is returning Address, which somehow contains null because of WCF weirdness.
