Do you happen to have the device driver CD? I think you should be able to find the 2.0 support that you need if you install the drivers from the device driver CD, instead of the drivers from online.
Thankyou for your advise. I will test the compatibility of it.
One thing I have noted is that the help function of the Measurement Studio cannot be integrated into the VS2005's IDE as like that in VS2003 edition.
PS. I install the device driver from the CD and cannot found the 2.0 Languages Support.
Have you tried implementing the same strategy as above, but using the folder:
\Program Files\National Instruments\MeasurementStudioVS2005\DotNET\Assemblies\Current.
