Does WPF have a Timer control?

I can't seem to find it in the Toolbox.

I've did a Google search, and found: http://www.c-sharpcorner.com/UploadFile/mahesh/WPfTimer09292009090518AM/WPfTimer.aspx

However, I can't seem to add a reference to System.Windows.Threading because 开发者_如何学Goit isn't displayed as an available library.

I've even made sure to use the full .NET4 framework, and not the client framework.

Any suggestion on what to try next?

Thank you.

No there is no timer control. You can for example use a DispatherTimer for this purpose.

It is defined in WindowsBase.dll, System.Windows.Threading is just the namespace of it.

It does,

it's System.Timers.Timer. It doesn't have any graphical component though.

Dim otimer As System.Timers.Timer

you can also find from System.Windows.Threading namespace's DispatcherTimer control
