We have a legacy application that is built in Windows Forms and C# but in recent years we've been doing a lot of work in Python. We want to evolve this tool and gradually move all of the backend code to Python but still have a Windows desktop front-end either in Windows Forms (as is currently) or WPF.

I have already looked at different options building parts of the core libraries in IronPython or even using a REST web server to call the Python core but quite sure yet. Has anyone does this and are there any example applications that you know off using this idea?

I was wondering if there are any open source engines that would allow us to build on in order to connect different APIs together. There are a lot of very expensive SaaS platforms out there that do this kind of thing but we would like to use something open source and add multiple sources and targets. We want to be able to connect Google Analytics API calls for example as a source with a middle layer that runs some transformations and then targets a marketing tool. Any suggestions?
