Question

After creating a new Silverlight application from the JetPack theme template that was installed, I try to follow the instructions provided in the App.xaml file about how to enable themeing of silverlight toolkit controls,

            <!--
            <ResourceDictionary Source="Assets/ToolkitStyles.xaml"/>
            To extend this theme to include the toolkit controls:
            1. Install the Silverlight Toolkit for Silverlight 4
            2. Add a Toolkit control to your project from the toolbox. This will add references to toolkit assemblies.
            3. Change the "Build Action" for ToolkitStyles.xaml to "Page"
            4. Uncomment the resource dictionary include above.

            If you do not intend to use toolkit controls, delete this comment and the ToolkitStyles.xaml file.-->

I follow the instructions correctly but the project now does not compile, here are the 39 or so errors it throws out.

I’m new to Silverlight (coming from MVC/jQuery) and it might be something I’m doing.

Answer 1

Looks like Toolkit problems. What references have you got in the project?

There are quite a few assemblies that make up the toolkit. Looks like some of them it wants are ‘System.Windows.Controls.DataVisualization.Toolkit’ and ‘System.Windows.Controls.Input.Toolkit’. The DockPanel is part of ‘System.Windows.Controls.Toolkit’ or something similar so that one might have been added when you dragged a DockPanel in.
