Log4net in Azure

Question

Hi,
I have an existing application which uses log4net framework for Logging purpose.Now i want to use log4net  in azure with minimal change in my existing code.
I have gone through various  post regarding log4net in azure development  forum but it didnt help me .
I have gone through following post :-

Now what i would like to do is save all the log from log4net to azure  table storage(azure storage service) .
In all the post it was mentioned that to set up config file for log4net in
SERVICECONFIGURATION.CSFG but when i try to set up configuration in service configuration for log4net ,the project doesn't compile.please help me on this to configure service configuration for log4net .
SO i am stuck up  in setting up log4net confing file, and specify the config
file in ServiceConfiguration.cscfg and setting up DiagnosticMonitor and log4net in OnStart method of WebRole.cs
Any tutorial for setting up log4net in windows azure will be very helpful.
Any help will be appreciated .

Hi,
If you use an log4net appender that writes to the diagnosticsonly, you can configure you log4net straight from code no config nessecary:
This is my config which works for me:
 in your webrole:
public override bool OnStart()
var config = DiagnosticMonitor.GetDefaultInitialConfiguration();
config.Directories.ScheduledTransferPeriod = TimeSpan.FromMinutes(1);
config.Logs.ScheduledTransferPeriod = TimeSpan.FromSeconds(20);
config.WindowsEventLog.ScheduledTransferPeriod = TimeSpan.FromSeconds(20);
config.WindowsEventLog.ScheduledTransferLogLevelFilter = LogLevel.Verbose ;
DiagnosticMonitor.Start("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString", config);
return base.OnStart();
in you global.asax.cs
void Application_Start(object sender, EventArgs e)
CloudStorageAccount.SetConfigurationSettingPublisher((configName, configSettingPublisher) =>
var connectionString = RoleEnvironment.GetConfigurationSettingValue(configName);
configSettingPublisher(connectionString);
// Code that runs on application startup
var appender = new AzureAppender();
appender.ActivateOptions();
BasicConfigurator.Configure(appender);
