Description

Windows added support (in Win 10.14290) for AF_HYPERV (for Hyper-V hosts/ Windows guests) and Linux support for AF_VSOCK has existed in mainline kernel since 3.9 (for Linux hosts/guests). This is useful for IPC communication between process on the hypervisor and in the guest OS

For example, this is what the Docker Desktop for Windows uses to communicate with the Docker Daemon when running in WSL2. I can see this being super useful for workloads like gRPC.

Research direction
Investigate .NET support for AF VSOCK and AF HYPERV socket families; identify current socket binding code in Kestrel; implement binding using platform specific APIs (e.g., Sockets.PlatformAbstractions). Test on Windows and Linux systems.
