[Solved] UserControl: XamlParseException

Jun 18, 2014 at 10:51 AM
Hi everybody,

I'm a newbie to OxyPlot and WPF. I was able to run this example and adding some more fun stuff in a stand-alone application.
But when I try to make a User Control Library I keep getting a XamlParseException: impossible to load OxyPlot.Wpf, PublicKeyToken=75e952ba404cdbb0

In the main program I simply have an empty window with my control. The xaml in VS renders fine!

I'm using VS 2013 Update 2, Win 7, .net 4 or 4.5 behaves the same.
Oxyplot is 2014.1.318.1

It's probably a stupid trivial error, but I need somebody to point me to the right direction!
<UserControl x:Class="WpfControlLibrary1.UserControl1"
             d:DesignHeight="300" d:DesignWidth="300">
        <oxy:PlotView Title="{Binding Title}">
                <oxy:LineSeries ItemsSource="{Binding Points}"/>
namespace WpfControlLibrary1
    /// <summary>
    /// Interaction logic for UserControl1.xaml
    /// </summary>
    public partial class UserControl1 : UserControl
        public UserControl1()

    public class MainViewModel
        public MainViewModel()
            this.Title = "Example 2";
            this.Points = new List<DataPoint>
                                  new DataPoint(0, 4),
                                  new DataPoint(10, 13),
                                  new DataPoint(20, 15),
                                  new DataPoint(30, 16),
                                  new DataPoint(40, 12),
                                  new DataPoint(50, 12)

        public string Title { get; private set; }

        public IList<DataPoint> Points { get; private set; }

Yep, this was very trivial.
For some reason VS was not copying OxyPlot.wpf.dll in the necessary path... I had to do it manually.
Oddly enough this happened also on another PC with Windows 8.1...

Did you use the OxyPlot.Wpf NuGet package? Maybe there is something that should be fixed..

Yes, I installed it from the NuGet Package Manager (not the console).
