Possible Errors while running in VS 2010
The namespace or namespace name 'log4net' could not be found
If you have added a reference to log4net correctly and added your usings, you may get a compile error “The type or namespace name ‘log4net’ could not be found (are you missing a using directive or an assembly reference?)”.


This is most likely due to the Target framework being set to .NET Framework X Client Profile. Change this to .NET Framwork 4 (full version) and your application will compile.

IsDebugEnabled, IsErrorEnabled, IsFatalEnabled is flase

Before:

After:    

Use below code before writing the log  

log4net.Config.XmlConfigurator.Configure()
