title: Can't find OxyPlot.Wpf PlotView
body: <p>Using Visual Studio 2013, my XAML code can't seem to find the PlotView in the OxyPlot.Wpf library. 
  I have used (not at the same time)</p>
  
  <pre><code>xmlns:oxy="OxyPlot.Wpf"
  xmlns:oxy="http://oxyplot.org/wpf"
  xmlns:oxy="clr-namespace:OxyPlot.Wpf;assembly=OxyPlot.Wpf"
  </code></pre>
  
  <p>There are several different ones referenced in the docs, I'm assuming that worked with different releases. I'm using runtime version v4.0.30319
  and version 2014.1.546.0 
  Any ideas on what reference I should be using or what else it could be?</p>
  
  <p>Thanks in advance</p>
