I don’t know anything about xdebug but I gather that you’re trying to connect from a container that’s running in Docker for Windows to an app that’s running and listening on a TCP port directly on the Windows 10 host?
That’s not really a supported scenario.
Having said that, there’s no reason it should not work.
10.0.75.1 is probably the IP of your Windows host on the
DockerNAT network (it is for me).
If I run a webserver on the Windows 10 host and make sure that it listens for external connections (listening on
locahost will probably not cut it) and completely disable Windows Firewall, I can curl the webserver from a linux container running in Docker for Windows:
curl 10.0.75.1:5000 Hello from ASP.NET Core!
Note that this is not supported and that the networking setup may vary between machines and may change in the future.
