title: CallMethodAction: can it be used in WPF?
body: <p>When i use <code>CallMethodAction</code> in MVVM-WPF i get this error:</p>
  <blockquote>
  <p>&quot;CallMethodAction&quot; does not exist in the namespace
  &quot;http://schemas.microsoft.com/expression/2010/interactions&quot;.</p>
  </blockquote>
  <p>knowing that i include the following namespaces in my xaml:</p>
  <pre><code>xmlns:i=&quot;http://schemas.microsoft.com/expression/2010/interactivity&quot;
  xmlns:ei=&quot;http://schemas.microsoft.com/expression/2010/interactions&quot;
  </code></pre>
  <p>And if it is for SL only, what is the equivalent in WPF</p>
