visual studio .net enterprise tools: Hi

I am new to application blocks. I have been asked to write some
customized formatters. This is what I need to do,

1. Using Tracer I need to be able to write trace log for methods of
interest.
2. The format of the written out trace log should be,
- Time
- Namespace
- Class name
- Method name
- Parameters and variables inside the method
- Elapsed time for executing that method

Is there anyone who has done something similar? I would like to know if
this can be acheived.
Looking at the Tracer class, I noticed that overriding this class
doesn't help.

Thanks in advance.

Maybe the log4net will be suitable for you.
