Which technology to choose for a desktop service?

Question

Software design

Good afternoon.
You must select a technology to develop the service.
Requirements:
- cross-platform (Win, Linux, Mac).
- the service must work with incoming requests from the desktop software, as well as interact with a remote server (HTTP).
- applications with which the service interacts are usually written in C#/C++ .
- user "communication" with the service is not required, it should provide an API for desktop application developers.
Wish: It would be nice not to pull a bunch of dependencies yet. because setting the service by the user should be as simple as possible.
you probably need something like WCF, but cross-platform. .NET CORE?
