title: Why Clipboard.SetText doesn't work?
body: <p>I have problem with copy some text to clipboard.
  My code looks like this:</p>
  
  <pre><code>    using System;
      using System.Windows;
      namespace namespace
      {
          public class Class1
          {
              public void Method1()
              {
                  Clipboard.SetText("some text");
              }
          }
  }
  </code></pre>
  
  <p>but on  line <code>Clipboard.SetText("...");</code>
  There is error message</p>
  
  <blockquote>
    <p>CS0103 The name 'Clipboard' does not exist in the current context</p>
  </blockquote>
  
  <p>What am I doing wrong? </p>
