Assembly attribute ´System.Runtime.InteropServices.GuidAttribute´ is not valid: Assembly custom attribute ´System.Runtime.InteropServices.GuidAttribute´ was specified multiple times with different values<BR><BR>Above is the error I get when building an application that previously built. What brings on this error??? (Which is followed also by the error: Attribute ´System.CLSCompliantAttribute´ cannot be specified more than once in this project, even with identical parameter values.)<BR><BR>Any input would be greatly appreciated!<BR>
