Unix domain socket support for Windows

[Insvald]

What is the problem you're trying to solve Containerd works via named pipes in Windows, but gRPC over named pipes is not supported in C# in the meantime. Good news that we can use sockets: https://docs.microsoft.com/en-us/aspnet/core/grpc/interprocess

Describe the solution you'd like Support gRPC clients working with Unix domain sockets in Windows as well as in Linux, and two types of configuration in config.toml for Windows system: both named pipes and Unix domain sockets.

Kestrel has built-in support for UDS endpoints. UDS are supported on Linux, macOS and modern versions of Windows.

Wow. I didn't know that. If Go supports Unix domain sockets in Windows, containerd should work without any changes in our side. Isn't it?

Yes, hopefully

This would be pretty cool, can look into this. iirc there were some issues/bugs with uds on some newer versions of windows. Have to remember what the issue(s) were first..

@Insvald I was able to make a PoC to talk to containerd on windows via named pipes. Please look at https://github.com/danespinosa/containerdclient/blob/main/Program.cs

It does work pretty well, although I am trying to talk to the .NET team to understand if this would be the best way :) Please let me know your thoughts, I hope this helps.

@danespinosa Great job! I absolutely must see how this work with my tests )).

@Insvald I have updated the sample, hope it helps you :)
