Can't you do the following?

No!
The class given as parameter to typeof(..) have to implement the
interface. The interface is the service contract, which the server
implements.
I have worked around the problem with a stub, that loads and runs the
python script, see attachment. For each stubbed method it calls the
python implemented method:
It would be smart to get rid of the stub.
You could at least define the stub in C# with empty implementations -
and then have your Python class subclass that directly rather than from
the interface. You could then cast pyClass to the concrete type rather
than the interface.
A *bit* less work and cleaner. The joy of statically typed languages. :-)

C# stub:
public class CalculatorServiceStub : ICalculator
{
private ICalculator pyCalc;
public CalculatorServiceStub()
{
if (Program.pyr != null)
{
Program.pyr.loadscript(@"..\..\..\Calculator\Calculator.py");
Program.pyr.run();
pyCalc = (ICalculator)Program.pyr.getInstance("PyCalculator");
}
}
public double Add(double n1, double n2)
{
return pyCalc.Add(n1,n2);
}
public double Subtract(double n1, double n2)
{
return pyCalc.Subtract(n1, n2);
}
public double Multiply(double n1, double n2)
{
return pyCalc.Multiply(n1, n2);
}
public double Divide(double n1, double n2)
{
return pyCalc.Divide(n1, n2);
}
}
The class PythonRunner is an adapter for loading, compiling, excuting,
instantiating objects and exchanging variables in and out of the
script Calculator.py.
