Debashish,

The logger named 'ClassLibrary1' references to an appender called 'application' which doesn't exist in the configuration file, this is an invalid reference that will throw and exception internally in the log4net assembly.

You can read debugging output from log4net by adding these key to your application cofiguration file:

<appSettings>
<add key="log4net.Internal.Debug" value="true"/>
<add key=""log4net.Internal.Quiet" value="false"/>
</appSettings>

Also, remember to call XmlConfiguration.Configure()
