QUESTION: I am looking for some VB.Net samples and have not been able to 
find any. This would be a lot of help.

QUESTION/PROBLEM:
Specify the version of log4net you are using. ->Latest Beta 1.2.0 Beta 8
Specify what your assembly type is, i.e. exe or dll, and how your code is 
launched, e.g. console application, windows application, ASP.NET project, 
COM+ hosted object, etc... ->Console Application

Specify which runtime platform (e.g. MS .NET, Mono, SSCLI) you are using and 
which version. -> .Net

MY ERROR IS:
