System.Drawing Reference Missing

[dsh2687]

When converting several custom indicators I created under Ninjatrader 7 to Ninjatrader 8, I am trying to define the Using reference System.Drawing at the top of my script (see attached picture). However the Drawing reference does not show up under the System object.

I am receiving the compiler error "The type or namespace StringFormat could not be found" which is defined under the System.Drawing object.

I am running Ninjatrader 8 under OS Windows 10. I am able to see the .Net 4.6 System.Drawing object under MS Visual Studio object browser so I know its there. Plus I am able to see the System.Drawing reference object when I run Ninjatrader 7 - just not under Ninjatrader 8.

Any ideas?

Hello dsh2687,

Thank you for writing in. NinjaTrader 8 uses System.Windows.Media instead of System.Drawing so System.Drawing is not included by default. To add a reference to the System.Drawing namespace so it can be used please follow the steps below:

Create a new NinjaScript Editor.
Open a file and right click in the editor.
Choose "References...".
Click "add".
Browse to the .Net assemblies folder (should be %windowsdir%\Microsoft.NET\Framework\v4.0.30319 or something similar).
Select "System.Drawing" and click add.

This will add in the System.Drawing.dll to the references for NinjaTrader.Custom.dll so you can add a using declaration.

Please let me know if this does not resolve the issue or if I may be of further assistance.
