What is the namespace for DispatcherTimer class?

Question

Ok! This sounds like a "Let Me Google That For You", well I did and here is the MSDN link:

http://msdn.microsoft.com/en-us/library/system.windows.threading.dispatchertimer.aspx

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

What is going on? I want be able to use DispatcherTimer class.

Answer 1

The MSDN page also says:

Assembly: WindowsBase

Did you reference this assembly? Is your project even a WPF project? (WindowsBase is a WPF library.)

Answer 2

You need to add a reference to WindowsBase.dll. It's a WPF assembly.
