title: The type or namespace name 'Capture' could not be found EMGU
body: <p>I am testing out <code>EMGU</code> for a school assignment, and I am following <a href="https://www.c-sharpcorner.com/UploadFile/shubham0987/creating-first-emgu-cv-project/" rel="nofollow noreferrer">this</a> tutorial to get a basic understanding with the way <code>EMGU</code> works, but I have a problem.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using System.ComponentModel;
  using System.Data;
  using System.Drawing;
  using System.Linq;
  using System.Text;
  using System.Threading.Tasks;
  using System.Windows.Forms;
  using Emgu.CV;
  using Emgu.CV.CvEnum;
  using Emgu.CV.Structure;
  using Emgu.CV.UI;
  
  namespace FacialRecognition
  {
      public partial class Form1 :Form
      {
          private Capture _capture;
          bool CapturingProcess = false;
          Image&lt;Bgr, Byte&gt; imgOrg;
          Image&lt;Gray, Byte&gt; imgProc;
  
          public Form1()
          {
              InitializeComponent();
          }
  
          private void Form1_Load(object sender, EventArgs e)
          {
              try {
                  _capture = new Capture(CaptureType.DShow);
              } catch(NullReferenceException ex) {
                  MessageBox.Show(ex.Message);
                  return;
              }
          }
  
          void processFunction(object sender, EventArgs e)
          {
              imgOrg = _capture.QueryFrame();
              if(imgOrg == null) return;
              imgProc = imgOrg.InRange(new Bgr(50, 50, 50), new Bgr(255, 255, 255));
              imgProc = imgProc.SmoothGaussian(9);
              original.Image = imgOrg;
              processed.Image = imgProc;
          }
      }
  }
  </code></pre>
  
  <p>However, I get the error:</p>
  
  <pre><code>The type or namespace name 'Capture' could not be found (are you missing a using directive or an assembly reference?)
  </code></pre>
  
  <p>and it suggests <code>using System.Text.RegularExpressions;</code>, which is quite strange.</p>
  
  <p>I'm guessing I am missing something, but I referenced all of the DLL's 
  in the tutorial. Here are some screenshots:</p>
