This C# solution provides 2 Log4Net appenders.
The first one is an appender to send mail through an Exchange Server.
The second one is an appender to log exceptions (or whatever) as a Work Item (Bug) in Visual Studio Online.
The configuration to do with the SMTPAppender provided by Log4Net is difficult when you have to send a mail through Exchange and a company proxy.
Obviously this appender is not as powerful as the SmtpAppender, but he logs correctly what you want by email.
You have to configure your Log4Net.config with your own settings, and put SendMailExchange.dll in the folder where Log4Net.dll is.
Sample Log4Net.config :
<log4net>
<!-- Beginning of the ExchangeAppender configuration-->
<appender name="Exchange" type="SendMailExchange.ExchangeMailAppender, SendMailExchange">
<recipient value="mail@whatever.com"> <!-- if not setted, will use the defaultRecipient setted in the configuration file-->
<mailAddressForUrl value="mail@company.com"> <!-- if not setted, will use the defaultRecipient setted in the configuration file-->
<layout type="log4net.Layout.PatternLayout,log4net">
<conversionPattern value="LEVEL: %level %newlineDATE: %date{dd/MM/yyyy HH:mm:ss,fff} %newlineLOGGER: %logger %newline%newline%message" />
</layout>
</appender>
<!-- End of the ExchangeAppender configuration-->
<root>
<level value="ALL"/>
</root>
<logger name="DebugLogger">
<level value="DEBUG"/>
</logger>
<logger name="MonitoringLogger">
<level value="INFO"/>
</logger>
<logger name="ExceptionLogger">
<level value="ERROR"/>
<appender-ref ref="Exchange"/>
</logger>
</log4net>
When you work with visual studio online, you may want to have backlog from your application bugs, in visual studio.
You have to configure your Log4Net.config with your own settings, and put VisualStudioOnlineBugAppender.dll in the folder where Log4Net.dll is.
Sample Log4Net.config :
<log4net>
<!-- Beginning of the VisualStudioOnlineBugAppender configuration-->
<appender name="OnlineBug" type="StudioOnlineBugAppender.OnlineBugAppender, StudioOnlineBugAppender">
<vsoProject value ="MyProject"/>
<vsoAccountName value ="MyAccountName"/>
<proxyUrl value ="http://proxy.company:proxyport"/>
<useProxy value ="true"/> <!-- don't set it or use false if you don't want to use a proxy-->
<!-- If you want to authenticate in visual studio online with your token -->
<vsoAuthenticateWithToken value ="true"/>
<vsoToken value ="token"/>
<!--
If you want to authenticate with your visual studio online account :
<vsoAuthenticateWithToken value ="false"/>
<vsoUsername value="username"/>
<vsoPassword value="password"/>
-->
<layout type="log4net.Layout.PatternLayout,log4net">
<conversionPattern value="LEVEL: %level %newlineDATE: %date{dd/MM/yyyy HH:mm:ss,fff} %newlineLOGGER: %logger %newline%newline%message" />
</layout>
</appender>
<!-- End of the VisualStudioOnlineBugAppender configuration-->
<root>
<level value="ALL"/>
</root>
<logger name="DebugLogger">
<level value="DEBUG"/>
</logger>
<logger name="MonitoringLogger">
<level value="INFO"/>
</logger>
<logger name="ExceptionLogger">
<level value="ERROR"/>
<appender-ref ref="OnlineBug"/>
</logger>
</log4net>
