HRESULT: 0x80131040: The located assembly's manifest definition does not match the assembly reference

Question

The located assembly\'s manifest definition does not match the assembly reference

getting this when running nunit through ncover. Any idea?

Answer 1

In my particular situation, I got this as a result of a CreateObject done in VBScript. The cause in my case was a version of the assembly that resided in the GAC, that was older than the one I had compiled. (trying to solve an earlier problem, I installed the assembly in the GAC).

So, if you're working with COM visible classes, then be sure you remove older versions of your assembly from the GAC, before registering your new assembly with RegASM.
