Reference to 'netstandard, Version=2.0.0.0, ...

[raffu]

Hi

Current 8.0.23.0 version says that it support :
.NET 4.8 Upgrade
General
Feature #14630

and it seems that I managed to add to strategy or indicator after installing ML.NET and adding reference to it C:\xxx\xxx ... \Microsoft.ML.152\lib\netstandard2.0\Microsoft.ML. Core.dll ...

using Microsoft.ML;
using Microsoft.ML.Data;

this will compile !

but if I add any next steps like

MLContext mlContext = new MLContext(seed: 0);

to the code, it does not compile but gives an error:

The type 'System.Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'.


Any help ? so what needed and where to be added or configured?
Something simple or not possible?
( the ML.Net support that .Net 4.8 platform)

Hello raffu,

Thank you for your post.

Netstandard is one of the .Net framework versions but it is not used with NinjaTrader. If you were in Visual Studio and changed it to use Netstandard, you'd need to change back to either 4.8 if you've updated or 4.5 if you're not. The project NinjaTrader uses is .Net framework so if you have changed the project over to a Netstandard project you'd need to delete the project and then uninstall and reinstall the platform.

Please let us know if we may assist further.

Hi, I actually installed that Microsoft.ML stuff with visual studio using .net framework 4.8 application and got the libraries from there .. and added references to those libraries got from there.
(Actually I don't even use Visual Studio anyway with NinjaTrader, no idea how .. NinjaScript Editor is good enough for me)


Anyway have anyone able to to use those Microsoft.ML libraries with NT?
That's more or less my q. as this is more or less not NT support issue.

Hey raffu and Brandon, I am having the same issues. I created a project in Visual Studio using .NET 4.8 but when I go to install Microsoft.ML from Nuget it has a dependency of .NetStandard V2.0 even the older version. To overcome this I have my Machine Learning model write to a text file and then NinjaTrader reads from that file on trades it needs to make, this is a terrible solution right now as I have to sleep the thread for Ninja to read the file, it messes up my backtests sometimes but real time so far is decent. Please if anyone has any other solutions feel free to reply, need ML in Ninja.
