Description

I've a .Net 4.0 windows service application that uses log4net.

Here's my log4net config.
<log4net>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property

{Context}] - %message%newline" />
</layout>
</appender>

<appender name="ColorConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
<mapping>
<level value="ERROR" />
<foreColor value="Red, HighIntensity" />
</mapping>
<mapping>
<level value="FATAL" />
<foreColor value="Red, HighIntensity" />
</mapping>
<mapping>
<level value="WARN" />
<foreColor value="Blue, HighIntensity" />
</mapping>
<mapping>
<level value="INFO" />
<forecolor value="White, HighIntensity" />
</mapping>
<mapping>
<level value="DEBUG" />
<forecolor value="Green, HighIntensity" />
</mapping>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{Context}

] - %message%newline" />
</layout>
</appender>

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<appendToFile value="true" />
<datePattern value="yyyyMMdd" />
<file value="Logs/Server.log" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property

{Context}] - %message%newline" />
</layout>
<maximumFileSize value="10MB" />
<rollingStyle value="Composite" />
<staticLogFileName value="true" />
</appender>

<appender name="EventLogAppender" type="log4net.Appender.EventLogAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{Context}

] - %message%newline" />
</layout>
</appender>

<root>
<level value="ALL" />
<appender-ref ref="ColorConsoleAppender" />
<appender-ref ref="RollingFileAppender" />
</root>

</log4net>

Logging works as expected when the service starts up while using the exe that was built in debug mode (log files are created at the right file path), but doesn't work when it is using the exe built in release mode.

I've even tried using a recompiled log4net dll for .Net 4.0 following the steps mentioned at this blog.. http://tseonet.blogspot.com/2010/07/making-log4net-run-on-net-40.html.
That didn't work either. I was able to compile and run the service. But the result was the same; no logs when using the exe build in release mode.

Not sure what's going on. Cannot deploy the application built in debug mode into production.

Any help is greatly appreciated.
