I am writing a class library assembly in C# .NET 3.5 which is used for integration with other applications including third-party Commercial-Off-The-Shelf (COTS) tools. Therefore, sometimes this class library will be called by applications (EXEs) that I control while other times it will be called by other DLLs or applications that I do not control.
- I am using C# 3.0, .NET 3.5 SP1, and Visual Studio 2008 SP1
- I am using log4net 126.96.36.199 or greater
Any solution must:
- Allow for the class library to enable and configure logging via it's own configuration file, if the calling application does not configure log4net.
- Allow for the class library to enable and configuring logging via the calling applications configuration, if it specifies log4net information
- Allow for the class library to enable and configuring logging using it's own configuration file at all times.
When my stand-alone class library is called by a DLL or application that I do not control (such as a third-party COTS tool) and which doesn't specify log4net configuration information, my class library is unable to do any of it's logging.
How do you configure and enable log4net for a stand-alone class library assembly so that it will log regardless if the calling application provides log4net configuration?
