Building is driven by make (or mingw32-make.exe). By default both Linux and Windows binaries are build.

Linux builds are done via Dockerfiles and create static binaries.

Windows builds require MSBuild, Visual Studio and Windows SDK installed with a minimum version of 14290. The project/solutions assumes 14291, so you may have to adjust the WindowsTargetPlatformVersion in the project files.

All sample application assume a service ID of 3049197C-FACB-11E6-BD58-64006A7986D3 which needs to be registered once using:

$service = New-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization\GuestCommunicationServices" -Name 3049197C-FACB-11E6-BD58-64006A7986D3

$service.SetValue("ElementName", "Hyper-V Socket Echo Service")

The echo server is started with:

hvecho -s

The client supports a number of modes. By default, with no arguments supplied it will connected using loopback mode, i.e. it tries to connect to the server on the same partition:

hvecho -c

The client can be run in a VM and started with:

hvecho -c parent

which attempts to connect to the server in the parent partition.

Finally, if the server is run in a VM, the client can be invoked in the parent partition with:

client -c <vmid>

where <vmid> is the GUID of the VM the server is running in. The GUID can be retrieved with: (get-vm <VM Name>).id.
