New runtime error with Navigation and Legend in Silverlight 5

I have a working project with Map, Legend and Navigation objects. After changing project type from Silverlight 4 to 5 it still compiles. But I get a runtime error at InitializeComponent() in the Constructor.

System.Windows.Markup.XamlParseException occurred
Message=Set property 'System.Windows.FrameworkElement.Style' threw an exception. [Line: 91 Position: 85]
LineNumber=91
LinePosition=85
StackTrace:
       at System.Windows.Application.LoadComponent(Object component, Uri resourceLocator)
       at ***.ArcGisMap.View_ArcGisMap.InitializeComponent()
       at ***.ArcGisMap.View_ArcGisMap..ctor()
InnerException: System.Windows.Markup.XamlParseException
       Message=Failed to create a 'System.Type' from the text 'local:FeatureDataGrid'. [Line: 13 Position: 36]
       LineNumber=13
       LinePosition=36
       StackTrace:
            at MS.Internal.XcpImports.CreateFromXaml(UnmanagedMemoryStream stream, String sourceAssemblyName, Boolean createNamescope, Boolean requireDefaultNamespace, Boolean allowEventHandlers, String xamlResourceUriString, Boolean isBinaryContent)
            at System.Windows.Controls.Control.GetBuiltInStyle(IntPtr nativeTarget, IntPtr& nativeStyle)

The expception goes away if I recompile and run as Silverlight 4. Or get rid of both Navigation and Legend.

That is, I tried and, having something as simple as

    <Canvas x:Name='MainCanvas' Width="800" Height="600" >
        <esri:Map x:Name="MyMap" Background="White" Canvas.Left="5" Canvas.Top="5" WrapAround="True" Height="590" Width="790">
            <esri:LayerCollection xmlns:esri="http://schemas.esri.com/arcgis/client/2009">
                <esri:ArcGISTiledMapServiceLayer Url="http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer" />
            </esri:LayerCollection>
        </esri:Map>
        <esri:Navigation x:Name="Navigation" Canvas.Left="15" Canvas.Top="460" Map="{Binding ElementName=MyMap}" />
    </Canvas>

with this project, gives me this error. While the same Canvas without Navigation works. All library references point to dlls version 2.3.0.774

I would very much like to know what could be the cause of this and how to fix it.

try adding the following assemblies to your project and then building.

System.Windows.Controls.dll
System.Windows.Controls.Data.dll
System.Windows.Controls.Data.Input.dll
