Invoking NodeJS from C#

I happen to have a need for this. From my research it doesn't appear that NodeJS distributes a library by default. I can't find any recent and maintained PInvoke bindings for anything. So, asking here before I start to build something. I think the idea would be to rebuild node myself as a shared or static library, and then link it into some bridge C/C++ code, and then P/Invoke against that. But checking if somebody is aware of a better way to go about it.

I should alter the topic. I am specifically interested in inprocess scenarios.

there's the IJSRuntime if you want to call JS function from .net would be helpful if you can elaborate your exact use case?

I mean I don't know how I can be any more specific than pinvoking into nodejs. Anyways. My research has found a node has has a build option to produce the runtime into a libnode. Which unfortunately has a really crap C++ API surface. But which can then be wrapped in a flat C API for pinvoke.

And I found this project which is attempting to do the same: https://github.com/microsoft/node-api-dotnet Though it's pretty early, and I don't know what the progress is.
