It's a web project that initially was in Coldfusion in a windows environment and much of the code that does the heavy duty work was moved into a C#.net DLL. Now I am Mac based I would like to be able to test on my machine. But it may be that I can't.

This is beyond me, how would I go about doing that?

Thanks for the reply Dave, To confirm i have understood, are you saying that I need to install the J-Integra .NET bridge? 

I don't need to install this on production only development on my Mac. There isn't much documentation that relates to Mac on this but I wanted to first check I understood you. Thanks again.

I would be very surprised if this worked with .NET Core. I doubt it's documented one way or the other, because this integration predates .NET Core and it's a third-party product. I also don't know if this has been upgraded since it's been included, either. I would look at the documentation for the embedded third-party product (JIntegra? I don't remember offhand) and see what that has to say.

I would also try to avoid using this product in production, too. I left that out of my initial reply, but I don't think very much of it. I don't think it's especially reliable, etc.
