It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
In your project are you referencing to the right dll aswell as it will be calling that dll in GAC? can you check for duplicates in GAC of the same DLL but different version?
