NUnit and log4net Simple Example Console Application Tutorial

Prerequisites : you do know something about C# and building console applications

Download NUnit
Download log4net

While installing remember where do you install them, since later on you would have to find the following 2 dlls:
log4net.dll ( for the using log4net; using log4net.Config; part )
and nunit.framework.dll ( for the using NUnit.Framework; part of the code )

Create a new project in VS ( or another IDE in your choice )
Add the references to the above mentioned dll's

Copy paste the bellow code. Build your solution.
Start the Nunit GUI. Create new Nunit project. Navigate to the bin folder of the project copy paste the path of the produced executable ( it contains also the tests in it - than press F5 to verify that all the tests are ran.
