visual studio code - Connecting to remote linux server with VSCode through WSL - File location issue?

Question

When attempting to use VS Code / WSL to remote into a linux server hosted as a Digital Ocean droplet, we're getting this error:

As far as I can see, the issue lies with

[17:38:26.931] > no such identity: /home/user/.ssh/id_rsa: No such file or directory

However

ssh -vv [email protected] -i /home/user/.ssh/id_rsa

Successfully connects in the debug and server is accessed

debug1: Authentication succeeded (publickey).

So this must be some issue with specifying the location of id_rsa in the config file for VS Code.

Host 100.100.10.100
  HostName 100.100.10.100
  User root
  ForwardAgent yes
  IdentityFile /home/autosermo/.ssh/id_rsa

We have tried everything we can think of for the value of IdentityFile (...~/.ssh/id_rsa etc) but cannot nail it down.

What are the other possible locations / what path should be provided to IdentityFile here?

Thank you

WSL is a bit of a red-herring here. When you are using the "Remote - SSH" extension in VSCode, you aren't going through WSL at all. As you can see from this line in the output ...

[17:38:25.713] > OpenSSH_for_Windows_7.7p1, LibreSSL 2.6.5

... It's using OpenSSH for Windows.

The location for your private key in OpenSSH should be %userprofile%/.ssh (so something like C:Usersusername.ssh). Try placing it there. Also try executing your ssh command from PowerShell or cmd rather than WSL, since that's the one being used by VSCode.
