Log4Net Depedant library version conflict

[GoogleCodeExporter]

What steps will reproduce the problem?
1.compile your application that uses the latest log4net
2.link the modbus library that links to an older version of log4net
3.watch the assembly loader explode when it trys to execute any modbus calls.

What is the expected output? What do you see instead?
I expect that the modbus library NOT be compiled in such a way that it requires 
a specific version of log4net since the assembly loader can handle loading new 
versions of the same library.

What version of the product are you using? On what operating system?
nmodbus version 1.11.0.0
windows 7 Pro


Please provide any additional information below.
I was able to download source, and recompile the library adjusting a few 
properties on the dependent libraries to accomplish this change. Zero code 
changes to get this working, binaries should be delivered in this state.
