I am trying to implement yaf in my existing asp.net web application.For this purpose I downloaded C# yaf sample code “YAF.SampleWebApplication-v2.1.2-C” and configured to my IIS V5.1 WindowsXpSp3. I run this application under 4.0 framework of IIS. Whenever I run the application I am getting error ” System.IO.FileLoadException: Could not load file or assembly 'System.Core, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)”. I searched internet, but did not get if anyone else got such message. I checked the virtual directory for .net version through IIS , it shows 4.0.

Please help me find problem deploying YAF on my local machine. Then I plan to copy files to my live host.
