Windows 8 Application: String not found

Question

I am developing a Windows 8 App using XAML and C#. I created a resource dictionary for storing localization strings.

While using the " < String > " tag as it is, the compiler recognizes it but says it is not supported.

In my current configuration:

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:s="using:System">

    <s:String x:Key="start">Start</s:String>
    <s:String x:Key="pause">Pause</s:String>
    <s:String x:Key="stop">Stop</s:String>

    <s:String x:Key="deleteSelected">Delete Selected</s:String>

    <s:String x:Key="timer">Timer</s:String>
    <s:String x:Key="timers">Timers</s:String>
    <s:String x:Key="stopper">Stopper</s:String>
    <s:String x:Key="stoppers">Stoppers</s:String>
    <s:String x:Key="alarmClock">Alarm Clock</s:String>
    <s:String x:Key="alarmClocks">Alarm Clocks</s:String>

    <s:String x:Key="recordLap">Record Lap</s:String>
</ResourceDictionary>

This is the debug output:

Answer 1

Use this instead:

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

     <x:String x:Key="start">Start</x:String>
