I have a project I made in Visual Basic 2008 Express. I converted it from someone else\'s C# project, but it works. It has several DLL dependencies. I went to publish my pro
I just had this problem too. In my case the blabla.dll was referenced in my solution but blabla.dll was also used in another.dll which i had referenced in my project.
On checking the versions of both blabla.dll they were not the same. So i updated another.dll with the correct blabla.dll and then referenced the new another.dll in my solution. The error was gone.
In short: i was using 2 versions of blabla.dll
I hope this makes sense, if not let me know. :)
