What is the namespace for DispatcherTimer class?
<p>Ok! This sounds like a "Let Me Google That For You", well I did and here is the MSDN link:</p>

<p><a href="http://msdn.microsoft.com/en-us/library/system.windows.threading.dispatchertimer.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/system.windows.threading.dispatchertimer.aspx</a></p>

<p>so in MSDN it says it is System.Windows.Threading   but my VS IDE is giving error on it.</p>

<p>What is going on? I want be able to use DispatcherTimer class.</p>
