Also, using the library directly from the ipy shell does not trigger the
observed behavior.

app

 

How exactly are you doing this?  

.

 

I have a C# app that embeds python to run scripts.  

 

Given a script both the script and the app need to access the same library.
Both the script and the app create objects using the library.  The app links
to the shared library.  In addition, each hosted script has a preamble to
add a reference to, and imports namespaces from the shared library.

Subject: [IronPython] strange runtime error hosting Iron Python in C# app

 

Given a set of classes in a c# Library like the following:

 

    public interface IFoo

    {

        int Bar { get;}

    }

 

    public abstract class FooBase : IFoo

    {

        public abstract int Bar { get;}

    }

 

    public class FooConcrete1 : FooBase

    {

        public override int Bar { get { return 1; } }

    }

 

and a C# consumer:

       public class FooUser

    {

        public static int FooInt(IFoo a)

        {

            return a.Bar;

        }

    }

 

if I call FooInt from Python I'll get: "We Encountered an error: expected
IFoo, got FooConcrete1".

 

I suspect the error stems from adding an assembly as a reference inside the
python code in addition to referencing it in the C# project.  If this is the
case, how do I make referenced assemblies visible to the hosted python
module w/o using AddReference.?

 

Thanks,

 

Matt
