[Netcommon-developer] Common.Logging v2.0 preview ready for download

[Erich E. <eei...@gm...>]

The signed preview build for the upcoming version 2.0 of Common.Logging is
ready for download at 

<http://www.springframework.net/downloads/netcommon/>

What's new?
-----------
- added support for EntLib 4.1 logging
- extended ILog interface now includes XXXFormat( string format, params
object[] args ) signatures
- leveraging lambdas, the ILog interface offers a new & safe way to write
log statements:

   log.Debug( m=>m("value= {0}", obj.Value) );
  
  this ensures, that the whole expression is only evaluated when
LogLevel.Debug is enabled and thus saves 
  you from writing
  
   if (log.IsDebugEnabled) 
   {
     log.Debug("value={0}", obj.Value);
   }

  to avoid this overhead.


Upgrading
---------
All that's necessary for upgrading from 1.2 is copy the new assemblies in
place and specifying a version redirect. Recompiling your application of
course links your app to the new version w/o a redirect.
2.0 runtime (Common.Logging.dll) is fully binary backwards compatible.

Note to implementors of the ILog interface: Due to the extensions, you need
to extend your implementations as well. As an added benefit, 2.0 comes with
some convenience classes, making it easy to implement your own log system
integration. Check out AbstractLogger and AbstractSimpleLogger for more
information.


Spring.NET
----------
I removed the dependency of Spring and it's SPI implementation of ILog for
testing purposes, thus compiling & testing the codebase against the new
version is no issue anymore starting with the next nightly build of
Spring.NET

Give the new version a whirl and please send your feedback!

enjoy,
Erich
