Answer 1

Enterprise Library is a solid alternative to log4net and it offers a bunch of other capabilities as well (caching, exception handling, validation, etc...). I use it on just about every project I build.

Highly recommended.

Lots of log4net advocates here so I'm sure this will be ignored, but I'll add my own preference:

System.Diagnostics.Trace

This includes listeners that listen for your Trace() methods, and then write to a log file/output window/event log, ones in the framework that are included are DefaultTraceListener, TextWriterTraceListener and the EventLogTraceListener. It allows you to specify levels (Warning,Error,Info) and categories.

Writing to the Event Log in a Web Application
UdpTraceListener - write log4net compatible XML messages to a log viewer such as log2console

Answer 3

You can use built in .NET logging. Look into TraceSource and TraceListeners, they can be configured in the .config file.

Answer 4

As I said in another thread, we've been using The Object Guy's Logging Framework in multiple production apps for several years. It's super easy to use and extend.

Answer 5

Another good logging library is NLog, which can log to a lot of different places, such as files, databases, event logger etc.

Answer 6

I use The Object Guy's Logging Framework--as do most people who try it. This guy has some interesting comments about it.
