How is \\wsl.localhost implemented?

[fiddyschmitt]

Hi,

The \\wsl.localhost\ share is a nice way of accessing folders within WSL. Could you please let me know how it was implemented? I normally use Dokan to implement Virtual File Systems, so I'd like to understand how the \\wsl.localhost\ share works (preferably in C#).

Thanks!
Fidel

My understanding is that's 9P in both directions (windows->linux and linux->windows), if it's WSL2

I did the exactly same steps with you and got the same result.
