use C# DLL in another language

[tylerb]

I am trying to create a C# DLL that is going to be used in SmallTalk. Right now I am creating an extremely simple DLL (see below) within VS 2005 and the SmallTalk side is using the dotnet bridge to call its functionality.

All I want is to create an instance of Class1 from SmallTalk and call the "theString" property which is supposed to return a string. I am unfamiliar with SmallTalk (my mentor is using it) so I am not sure about the implementation there. I do know that the SmallTalk implementation works with other DLLs that have been created, yet I don't have the source for those DLLs. I keep getting an error in the SmallTalk that is stating it can't find the "theString" property.

My Questions:
How do I create a C# DLL that can be used over a dotnet bridge?
Is anyone here an expert on the dotnet bridge?
Would this be easier if I were to use C++ instead of C#? (seems that the dotnet bridge is maybe meant for C++ rather than C#)

using System;
using System.Collections.Generic;
using System.Text;
 
namespace simpleDLL
{
    public class Class1
    {
        private String myString;
 
        public Class1()
        {
            myString = "Hello World";
        }
 
        public String theString
        {
            get { return myString; }
            set { myString = value; }
        }
    }
}

Wow tough problem! I've never used small talk so I am not sure how their dotnet bridge is implemented. If the dotnet bridge is supposed to work with .net technolgies then you should be able to write the dll in any .net language and then pass it on to the bridge. Every dot net language should compile into the same MSIL file. You could try to implement it in C++ as a proof of concept to see if it works.

THANKS FOR THE REPLY!!!!! (first time I have ever posted a software question and someone actually replied quickly)

Yeah I figured the CLR/MSIL would solve any C++ vs C# discrepancies. I might have found a solution. I am going to try to create a .NET assembly rather than a DLL yet I know nothing about what I am doing so... we'll see :)

NOTE: I also just realized that the dotnet bridge is not a Microsoft product but rather a couple people that scrapped something together for Ruby
