I am getting the following warning and error message for a C# 2008 application I am working on:

Warning 17 The predefined type 'System.Runtime.CompilerServices.ExtensionAttribute' is defined in multiple assemblies in the global alias;
using definition from 'c:\Program Files (x86)\NLog\.NET Framework 2.0\NLog.dll' sample

Error 21 The type or namespace name 'Nlog' could not be found (are you missing a using directive or an assembly reference?) C:\Sample.cs 15 7 samplef

I am getting this error message since I am trying to add the NLog open source tool to the solution file for 3 different project files in this solution.

I am completing the following task:

1. I add a reference to this dll in the references section of each proejct file.

2. I then place a 'using NLog' statment in each proejct file.

Can you show me code and/or tell me how to fix this problem?
