Getting error on xaml binding code for BooleanToVisibilityConverter in MVVM
<p>I used progress bar in View as below:</p>

<pre><code>&lt;ProgressBar  IsIndeterminate="{Binding IsBusy}" Visibility="{Binding IsBusy,Converter={StaticResource BooleanToVisibilityConverter}}" HorizontalAlignment="Left" Height="33" Margin="46,222,0,0" VerticalAlignment="Top" Width="358"/&gt;
</code></pre>

<ul>
<li>BooleanToVisibilityConverter is defined in ViewModel</li>
<li>Getting Error on xaml code of view
<code>&lt;phone:PhoneApplicationPage.Resources&gt;</code>
<code>&lt;BooleanToVisibilityConverter x:Key="BooleanConverter"/&gt;</code>
<code>&lt;/phone:PhoneApplicationPage.Resources&gt;</code></li>
</ul>

<p>*Error is:</p>

<p>The name "BooleanToVisibilityConverter" does not exist in the namespace "<a href="http://schemas.microsoft.com/client/2007" rel="nofollow">http://schemas.microsoft.com/client/2007</a>".</p>
