Navigation Samples failing with Silverlight 3 because of URIMapping

[Yusuf]

The Books Sample and Car samples for Page Navigation are failing in Silverlight 3 with the following error.
System.Windows.Markup.XamlParseException occurred
  Message="AG_E_PARSER_UNKNOWN_TYPE [Line: 8 Position: 26]"
  LineNumber=8
  LinePosition=26
  StackTrace:
       at System.Windows.Application.LoadComponent(Object component, Uri resourceLocator)
       at BooksExample.App.InitializeComponent()
       at BooksExample.App..ctor()
  InnerException:

In order to debug the issue I tried the Silverlight Navigation Framework and that too failed. Further analysis showed that earlier navigation:Frame element we didn't specify the UriMapper. After explicitly setting the same it works fine. So is the issue with Book Sample similiar to this one? But I didn't see any property like UriMapper in the RadFrame? How to solve this issue?

Thanks & Regards,

Hello Yusuf,

This exception happens because you try to access internal or private resources .
In order to have working example in Silverlight 3 you have to do the following:

1.Go to Resource.Designer.cs ,  now you have the following code:

[global::System.Diagnostics.CodeAnalysis.SuppressMessageAttribute("Microsoft.Performance", "CA1811:AvoidUncalledPrivateCode")]
        internal Resource() {
        }

in order to work correctly  you have to make the constructor public:

[global::System.Diagnostics.CodeAnalysis.SuppressMessageAttribute("Microsoft.Performance", "CA1811:AvoidUncalledPrivateCode")]
        public Resource() {
        }

2.Go to App.xaml and verify that you reference the resource file correctly. For example :
 xmlns:local="clr-namespace:BooksExample"

<local:Resource x:Key="Resources"/>

I hope that this answers your question.
