[EntLib 5]: Logging between assemblies

I've got a project that I'm working Enterprise Library logging into, and that application is made up of multiple assemblies. The UI assembly, the domain assembly and some others. Is there a way to have the logging all go to the same location (in the case of rolling flat file)?

Edit> Now that I look at it further, can you even use EntLib loggin in a class library? None of the setup that I've used thus far is开发者_StackOverflow中文版 available because of a lack of an app.config for a class library.

Yes, multiple assemblies can log to the same file provided that they are all running in the same app domain.

For configuration you can use the FileConfigurationSource and use the factory method LogWriterFactory(IConfigurationSource) to create a LogWriter. See External configuration files in Enterprise Library for more information.

An alternative approach would be to forgo file based configuration and use programmatic configuration.
