Required library for acquiring images in Visual Studio?

[DanFriz]

I am trying using to use Visual Studio (2010 or 2017) C# to run a GigE camera to grab an image and run some compare function set up in NI Vision Development Module and Vision Assistant 2017. I added all the references from the NI folders but I seem to be missing the sessions one? Which reference should be the one that works?

The session is set up using:

            NationalInstruments.Vision.Acquisition.Imaqdx.ImaqdxSession session;

            session = new ImaqdxSession(comboBoxCameraName.Text);

            session.ConfigureGrab();

            uint bufNum = 0;           

            NationalInstruments.Vision.VisionImage img; // reference ?

            session.Grab(img, true, out bufNum);

            session.Close();

and it returns the following error:

Error 1 The type 'NationalInstruments.ISupportSynchronizationContext' 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'. G:\2817\Test2018\NItest\NI_Test\NI_Test\Form1.cs 17

Hi Dan,

Please note that, according to the Readme, Visual Studio 2010 and later are not officially supported:

That said, you could try the steps in the following KB if you think this issue is related. Howebver, I think the lack of support for Visual Studio is the more likely cause.
