title: What does this code means?
body: <pre><code>namespace myApplication    {
      public partial class Form1 : Form
      {
          public Form1()
          {
              InitializeComponent();
          }
      }
  }
  </code></pre>
  
  <p>What is <code>partial class Form1 : Form</code></p>
  
  <p>and what is <code>InitializeComponents();</code></p>
  
  <p>and why it is used <code>Form1 : Form</code> instead of only <code>Form1</code></p>
