Affectiva C# SDK crashes

Question

I just started using Affectiva SDK for C#, and after a few runs, I stumbled upon a continuous crash problem. I am using the Camera processing, on x86 architecture and .Net 4.5.1. I have VS 2013 installed. My OS is Windows 10. I have added "opencv_ffmpeg248" and "affdex-native" in my output. The code builds and runs ok, but from time to time, during runtime, it throws this errors and the application closes.

This is the code that I am using:

 public class Class1 : Affdex.ImageListener
{
    private Affdex.CameraDetector _detector;

    public event EventHandler<string[]> AllValuesEvent;

    public Class1()
    {
        _detector = new Affdex.CameraDetector();
        _detector.setDetectAllEmotions(true);
        _detector.setDetectAllAppearances(true);

        String classifierPath = @"C:\Program Files (x86)\Affectiva\Affdex SDK\data";
        _detector.setClassifierPath(classifierPath);
        _detector.setImageListener(this);
        _detector.start();
    }

    public void StopCamera()
    {
        _detector.stop();
    }


    public void onImageCapture(Frame frame)
    {

    }

    public void onImageResults(Dictionary<int, Face> faces, Frame frame)
    {
        if (faces.Count > 0)
        {
            Face face = faces.First().Value;

            Console.WriteLine("Age: {0} Gender: {1} Glasses: {2}",
                face.Appearance.Age,
                face.Appearance.Gender,
                face.Appearance.Glasses);

            string[] names = new string[8];
            string[] values = new string[8];

            names[0] = "Anger";
            names[1] = "Contempt";
            names[2] = "Disgust";
            names[3] = "Engagement";
            names[4] = "Fear";
            names[5] = "Joy";
            names[6] = "Sadness";
            names[7] = "Surprise";

            values[0] = face.Emotions.Anger.ToString("F2");
            values[1] = face.Emotions.Contempt.ToString("F2");
            values[2] = face.Emotions.Disgust.ToString("F2");
            values[3] = face.Emotions.Engagement.ToString("F2");
            values[4] = face.Emotions.Fear.ToString("F2");
            values[5] = face.Emotions.Joy.ToString("F2");
            values[6] = face.Emotions.Sadness.ToString("F2");
            values[7] = face.Emotions.Surprise.ToString("F2");

            RaiseAllValuesEvent(names, values);
        }
    }

    private void RaiseAllValuesEvent(string[] names, string[] values)
    {
        if (AllValuesEvent != null)
        {
            AllValuesEvent(names, values);
        }
    }
}

These are the errors that appear:

Anyone has any suggestions?

Thank you very much.

Hey, One problem might be that you are mixing debug and release DLLs .. Can you make sure that you import the DLLs that match your build profile. — ahamino, Oct 18 '16 at 18:20
Well, apparently, your suggestion seems to have solved my problem. I will continue monitoring it for the next few days to see if I still get the error using the release dlls and come back with the result. — Lupu Silviu, Oct 19 '16 at 07:46
hello, @ahamino your suggestion fixed my problem. Thank you. I don`t know how to flag your comment as the answer. — Lupu Silviu, Oct 31 '16 at 11:46

I am posting this here, to be able to mark as answer, and to have this topic closed.

As suggested by @ahamino in a comment, the issue was the fact that I have accidentally mixed debug dlls into my references. Adding only release dlls fixed my issue.

Thank you again @ahamino.
