i need it for DispatcherFrame function

Hello buildorbust, thanks for your post and welcome to the NinjaTrader forum.

Please first add a reference to the DLL by right-clicking the code>References.

After that, you must add "using System.Windows.Threading;" then you can instantiate a DispatcherFrame object.

Kind regards.
