I would like use from Spring.NET Aspect library Logging aspect together with log4Net. I found this article how to use log4Net with Common Logging API.
My test application is console and based on .NET 4.0 Client profile.
1st Attempt
So I refer in my project these libraries:
- Spring.Core version 1.3.2.40943, runtime v4.0.30319
- Spring.AOP version 1.3.2.40943, runtime v4.0.30319
- Common.Logging version: 1.2.0.0, runtime v1.0.3705
Assemblies above I have from Program Files\Spring.NET 1.3.2\bin\net\4.0
- log4net version: 1.2.10.0, runtime v2.0.50727
I couldn’t find assembly Common.Logging.Log4Net.dll in Program Files\Spring.NET 1.3.2\bin \net\4.0 so I download this assembly from SourceForge:
- Common.Logging.Log4Net version 2.0.0.0 runtime v2.0.50727
I configured logger in app.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<sectionGroup name="spring">
<section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
<section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core"/>
</sectionGroup>
<sectionGroup name="common">
<section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
</sectionGroup>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
<common>
<logging>
<factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net">
<arg key="configType" value="INLINE" />
</factoryAdapter>
</logging>
</common>
<log4net>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger %ndc - %message%newline" />
</layout>
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="ConsoleAppender" />
</root>
<logger name="myLogger">
<level value="DEBUG" />
</logger>
</log4net>
<spring>
<context>
<resource uri="config://spring/objects"/>
</context>
<objects xmlns="http://www.springframework.net">
</objects>
</spring>
</configuration>
and tried this:
ILog log = LogManager.GetLogger("myLogger");
log.Error("hello world");
I got this runtime error:
{"Could not configure Common.Logging from configuration section 'common/logging'."}
Inner exception:
{"An error occurred creating the configuration section handler for common/logging: Unable to create type 'Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net' (E:\C# PROJECTS\STUDY\SPRING.NET\SpringNet.Aspects\LoggingWithLog4Net\bin\Debug\LoggingWithLog4Net.vshost.exe.Config line 18)"}

at Common.Logging.LogManager.BuildLoggerFactoryAdapter()
2nd Attempt
I think problem must be in version of assembly Common.Logging.Log4Net version 2.0.0.0 runtime v2.0.50727. Because I used Common.Logging version: 1.2.0.0, runtime v1.0.3705.
So I changed Common.Logging version from 1.2.0.0 to 2.0.0.0. I used Common.Logging from SourceForge.
And tested again. I got this error:
Unable to create type 'Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net'
Inner exception:
{"Could not load file or assembly 'Common.Logging.Log4Net' or one of its dependencies. The system cannot find the file specified.":"Common.Logging.Log4Net"}
StackTrace:

3rd and last attempt
Finally I found assembly Common.Logging.Log4Net version 1.2.0.2 in spring examples so I used it.
- Common.Logging.Log4Net version 1.2.0.2
- Common.Logging version 1.2.0.0
- log4Net 1.2.10.0
Tested and got again error:
{"Could not configure Common.Logging from configuration section 'common/logging'."}
Inner exception:
{"An error occurred creating the configuration section handler for common/logging: Unable to create type 'Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net' (E:\C# PROJECTS\STUDY\SPRING.NET\SpringNet.Aspects\LoggingWithLog4Net\bin\Debug\LoggingWithLog4Net.vshost.exe.Config line 18)"}
StackTrace:
{"Unable to create type 'Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net'"}
I am really confuse what I do bad? Some problem with assemblies version?
