title: Silverlight Slider CustomConstrol properties not available
body: <p>I've create a custom control with Blend 4 to customize a Slide object. Here a snipet of code generated by Blend:</p>
  
  <pre><code>&lt;UserControl
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
      xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
      mc:Ignorable="d"
      x:Class="SilverlightControlCustomSlider.CustomSlider"
      d:DesignWidth="640" d:DesignHeight="480"&gt;
      &lt;UserControl.Resources&gt;
          &lt;Style x:Key="SliderStyle1" TargetType="Slider"&gt;
              &lt;Setter Property="BorderThickness" Value="1"/&gt;
              &lt;Setter Property="Maximum" Value="10"/&gt;
              &lt;Setter Property="Minimum" Value="0"/&gt;
              &lt;Setter Property="Value" Value="0"/&gt;
              &lt;Setter Property="BorderBrush"&gt;
  </code></pre>
  
  <p>Then I've build the project and imported it to VS2010. I can create an instance of the custom slider it has the same look and all. However, the properties Value, Maximum and Minimum (and maybe others) are not available. Like the custom control did not inherited from the slider. What am I doing wrong? </p>
  
  <p>Thanks</p>
