Hello - this is my first post so apologies if this is the wrong forum.

I'm trying to define a base class in C# and derive from that class in python / pythonnet. The C# class is very basic:

publicclassOrder{publicstringsymbol;publicvirtualvoidEvaluate(Barb){Console.WriteLine("from Order.Evaluate() - hello!");}}

In python I have the specific order class defined as:

classLimitOrder(Order):def__init__(self):self.symbol="SQ"defEvaluate(self,bar ):print("LimitOrder.Evaluate() - yay python!" )

In C# I have an OMS class with a method:public void AddOrder( Order order )

When I pass inLimitOrder and call a method in the OMS that callsEvaluate, theOrder classEvaluate method is called instead of theLimitOrder.Evaluate method.

I'm using python 3.6.7 and VS 2019 / .NET 4.7.2

In searching for this I'm only seeing 1 instance of a similar question being asked but no solid response. TheEvaluate() method (and entireOrder class for that matter) can be abstract but when I try that I get an error creating theLimitOrder object saying I can't create an abstract class.

Any help would be appreciated. Thanks in advance.
