Unable to load System.Text.Json

[dastaan]

Hi NT,

I am trying to add System.Text.Json file in NinjaTrader. However, It is throwing an error :

Could not load file or assembly 'System.Text.Json, Version=4.0.1.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.

The parent .NET version is the same i.e 4.8. I have placed it in the bin/custom folder and referenced it under script editor, the same way as I do with other dlls. While the other dlls are working fine this specific is giving an error.


Also, When I restart NT I get the below error :

Hello dastaan,

NinjaTrader uses the C# programming language for developing custom NinjaScript AddOns. Using external programming languages is not documented or supported and we would not be able to provide assistance.
Documents\NinjaTrader 8\bin\Custom is the proper place for a 3rd party referenced assembly dll.

Support for 3rd party assemblies is limited. Our team is able to assist with adding the dll and a reference to the dll, however we cannot assist with its use, or with any errors or unexpected behavior that may occur.

With that said, we are happy to forward any insightful information we happen to be aware of.

Below is a link to the help guide on referencing a 3rd party assembly dll.

Any referenced managed assembly will need to target .NET Framework 4.8 or lower. Other versions of .NET will not work, such as .NET Core or .NET 5.


Due to an internal change with 8.0.26.0, calls to Newtonsoft must be made to an external .NET 4.8 equivalent or to the netstandard.dll.

As a heads up, NinjaTrader does not guaranteeing the version of Newtonsoft.Json.dll that NinjaTrader is using internally.
