Why does System.Windows.Markup.XamlParseException throw when I try to use RadChartView in UserControl XAML?

[Eugene]

.I have the following error when I use RadChartView: 'System.Windows.Markup.XamlParseException' in PresentationFramework.dll with message: "Could not load file or assembly Telerik.Windows.Controls.Chart, PublicKeyToken=5803cfa389c90ce7 or one of its dependencies. The system cannot find the file specified". Below is UserControl XAML code where the exception is thrown.

<UserControl x:Class="DeviceStatus.Views.DeviceStatusView"

</UserControl>

I develop my WPF MVVM application using Prism 6. I use MS VS 2015 Professional as IDE. I had created the my app solution and shell project there using Prism Template Pack. The type of solution is Prism Unity App. After its creation I added Prism Module (WPF) and then added Prism UserControl (WPF) in Views folder of the Prism Module. XAML markup of this UserControl is shown above. Why does this error occur? Please help me eliminate it.

I've solved this problem in three steps:

1) Delete the View with RadCartesianChart from my Prism Module project,

2) Create a new View as Prism UserControl (WPF) in the Prism Module project,

3) Drug CartesianChart from Component Pannel to this new View.

So there is miracles and only! But nevertheless, why the error had place in old View deleted?

Hello Eugene,

With the code provided so far we could not reproduce the issue on our side. 

You can try to restart the Visual Studio, clean and rebuild the solution and delete the.suo files. Sometimes in such situation can be helpful even to restart the computer. Most probably the Visual Studio has cached something that is causing the exception.

I had recreated the instance of the control in XAML and error was eliminated.
