I have implemented log4net ver 1.2.13.0 without major problems.(.Net ver 4.51 C#4)
I add an AdoNetAppender following documentation.
But here is my piece of code causing some troubles :
<appender name ="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<bufferSize value ="1" />
<connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
I have a warning message not blocking my app but annoying and very disturbing :
The 'value' attribute is invalid - The value
'System.Data.SqlClient.SqlConnection, System.Data, Version=4.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089' is invalid according
to its datatype 'connectionTypeTypes' - The Enumeration constraint
failed.
Where is the problem and the solution to get rid off this message ?
Many thanks in advance.
The log4net schema file (http://csharptest.net/downloads/schema/log4net.xsd) has this definition:
<xs:enumeration value="System.Data.SqlClient.SqlConnection, System.Data" />
If you change your setting to match this value, the warning will disappear.

I have inherited an application which uses the configuration manager class to store and retrieve settings. In the app.config class there is custom section group "userSettings" which includes a "Server" property.
In the app.config file this value is defined as "a14". In Settings.Designer.vb the default is specified as "a5" yet when I try to access My.Settings.Server it brings back the value "a10", which is a value I previously used in the app.config file.
Not having much experience with the configuration manager, I am at a loss to determine where it is retrieving this value from and what I need to change so that it retrieves the correct server value.
For brevity, I have removed other settings from the code sample.
app.config:
<sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
<section name="WorkstationApp.My.MySettings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
...
<userSettings>
<WorkstationApp.My.MySettings>
<setting name="Server" serializeAs="String">
<value>a14</value>
</setting>
</WorkstationApp.My.MySettings>
</userSettings>
Settings.Designer.vb:
<Global.System.Configuration.UserScopedSettingAttribute(), _
Global.System.Diagnostics.DebuggerNonUserCodeAttribute(), _
Global.System.Configuration.DefaultSettingValueAttribute("a5")> _
Public Property Server() As String
Get
Return CType(Me("Server"),String)
End Get
Set
Me("Server") = value
End Set
End Property
Application code: (server is being set to "a10", but I want it to have the app.config value of "a14").
Dim Server As String = My.Settings.Server
It looks like I was expecting the wrong thing (well duh). I had these settings set as User settings, which are stored in the /appdata/ folder and had nothing to do with the app.config file at all.
The user config file had been set with the initial values and had never been modified subsequently with a My.Settings.Save. More details in this answer: Where are My.Settings saved in VB 2010 .NET?
I am trying to understand how log4net works so I've added this to my app.config (I should add that Console Appender and FileAppender work perfectly, I only have trouble with the AdoNetAppender).
How can I debug this, to see if at least the connection to db succeeds?
The problem is the INSERT statement isn't executed.
I should add the
Data Source=MyWorkgroup\SQLEXPRESS;Initial Catalog=MyNewDatabase;User ID=juan;password=juan,
works perfectly when I try to connect to SQL Server manually, so not sure if that's the problem.
Also, the ConnectionType was taken from the official site:
https://logging.apache.org/log4net/log4net-1.2.11/release/sdk/log4net.Appender.AdoNetAppender.ConnectionType.html
<?xml version="1.0" encoding="utf-8" ?>

Later edit (after using the debug method recommended by David):
haacked.com is indeed extremely interesting, great tip! However, it seems that it's describing what I'm instructing log4net to log, but not the result of those actions(?), if I'm reading this well (no failed/or succeeded?)
e.g.

I am trying to use PRISM for my application. I have been following Mike Taulty's video s on the same. I would like to know, if there is any sample code available for app.config file mentioned while loading modules without references. What I mean is I am looking to copy paste the configuration related information, instead of typing them from start to avoid mistakes. Also I would liek to know if the version number of the assembly is needed or not in the config file while we follow this approach.
My ModulesCatalog.xaml looks like this:
<Modularity:ModuleCatalog xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

I would also check PRISM samples (in PRISM installation folder)
Version needed, yes
I'm using the code here : ASP.NET How to get List of Groups in Active Directory
Specifically :
using System.DirectoryServices;
DirectoryEntry objADAM = default(DirectoryEntry); //compiler error!
Problem: compiler says that it doesn't know what DirectoryEntry is.
I tried to add it to my web.config:
<assemblies>
<!-- ... -->
<add assembly="System.DirectoryServices, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
</assemblies>
But it didn't seem to help so I tried to add a reference:
Someone suggested setting Copy Local = True but that didn't help either.
I noticed that I don't see a reference for System.DirectoryServices - only System.DirectoryServices.Accountmanagement
Can anyone help me get this code to compile? I'm not sure what to try next.
Take the .net 3.5 filter off in the Add Reference dialog, and then put a reference in your project to:
System.DirectoryServices, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
You can take the filter off by changing you project setting : http://msdn.microsoft.com/en-us/library/bb398202.aspx
If you want to use the DirectoryEntry from the System.DirectoryServices namespace - you need to add a reference to the System.DirectoryServices assembly - NOT the System.DirectoryServices.AccountManagement assembly!
This is only the 2nd time I've tried to use log4net. This is a Windows form app and I thought things are set up OK but I was not getting any logfile created. I found some advice about needing to explicitly make it read the app.config file so I added log4net.Config.XmlConfigurator.Configure() here:
public partial class GridForm : Form
{
public static readonly ILog log = LogManager.GetLogger(typeof(GridForm));
public GridForm()
{
InitializeComponent();
// Initialize log4net (make him read the app.config file)
log4net.Config.XmlConfigurator.Configure(); // this gives the exception
}
I have a little uncertainty about how I'm referencing the log4net.dll.
I have 2 projects in the solution - CBMI.Common which is a class library project and CBMI.WinFormsUI which is my forms project (startup form).
I copied log4net.dll to the bin directory of CBMI.Common (NOT the bin\debug folder)
then added a reference in my forms project that points to that location: CBMI.Common\bin
This compiles without error. I think that it should be OK, but...
I cannot determine what to do from the exception raised and messages shown:
System.IO.FileNotFoundException crossed a native/managed boundary
