Problem :
I am trying to run some of the unit tests in the C# Windows Forms application (Visual Studio 2005), however I am facing the below error :
System.IO.FileLoadException: Could not load file or assembly 'Utility, Version=1.2.0.200, Culture=neutral, PublicKeyToken=764d581291d764f7' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)**
When I try to look in my references, and I can only have the reference to Utility version 1.2.0.203.
Any pointers on how can I figure out what is trying to reference the old version of my DLL file?
