Hi All
There is strange problem in running the ArcGIS api for windows mobile.
Every thing is installed as per the stated guidelines on ESRI Resource center.
but when after install completion when i tried to make a simple map view application i followed the ways given on resource center.
everything seems to be fine on XAML as the compiler iis not prompting any error.
but when i am debuging it, its going to Unhandled Exception block.
the Detailed error retrieved from Exception Object is as followed:
Ist is MS.InternalWrappedException with message Could not load type 'System.Windows.FlowDirection' from assembly 'System.Windows, Version=, Culture=neutral, PublicKeyToken=7CEC85D7BEA7798E'.[/B
when i saw the internalException object for the above exception
then it was
System.MissingMethodException with message
Could not load type [B] 'System.Windows.FlowDirection' from assembly 'System.Windows, Version=, Culture=neutral, PublicKeyToken=7CEC85D7BEA7798E'.

My XAML File Is

    mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768"
    FontFamily="{StaticResource PhoneFontFamilyNormal}"
    FontSize="{StaticResource PhoneFontSizeNormal}"
    Foreground="{StaticResource PhoneForegroundBrush}"

    <!--LayoutRoot is the root grid where all page content is placed-->
    <Grid x:Name="LayoutRoot" Background="Transparent">

        <!--TitlePanel contains the name of the application and page title-->
        <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
