NationalInstruments. common dll version 8.7.35.131

Hello

I am using Visual Studio 2010, and I am trying to access  The digial ports on my NI USB-6210.

below I have C# code.  Trying to access the daq.  It is simple, but I can't use any NI device due to the dll that I have.

I have version 9.0.35.6  I would think that this would work with the previous versions for backward capatibility.

When I try to build the program it gives me this error.

Error 2 The type 'NationalInstruments.ISynchronizeCallbacks' is defined in an assembly that is not referenced. You must add a reference to assembly 'NationalInstruments.Common, Version=8.7.35.131, Culture=neutral, PublicKeyToken=18cbae0f9955702a'. 

I'm not sure if I need a different dll to reference or if there is something wrong with the dll.

Thanks.

using

{

(Task DRT = new Task())//Task DRT = new Task();

//find the correct port and use the default first value. DaqSystem.Local.GetPhysicalChannels(PhysicalChannelTypes.DIPort, PhysicalChannelAccess.External)[0],

DRT.DIChannels.CreateChannel(

                             "port0",

                             ChannelLineGrouping.OneChannelForAllLines);

DigitalSingleChannelReader reader = new DigitalSingleChannelReader(DRT.Stream);

int data = reader.ReadSingleSamplePortInt32();

It sounds like you need to add a reference to the DAQmx driver.  Here is another forum that discusses this. http://forums.ni.com/t5/Multifunction-DAQ/DAQmx-API-reference-Visual-Studio-2010-Windows-7/td-p/1408...
