workspaceMount/workspaceMount does not support Windows paths (Windows Containers issue)

[CarlosDomingues]

Problem

Using Windows paths in workspaceMount and workspaceFolder doesn't seem to be possible. Trying to use Windows paths as targets for either volumes and bind mounts will return Workspace folder in devcontainer.json must be an absolute path..

Information

• VSCode Version: 1.55.0-insider
• Local OS Version: Windows 10
• Remote OS Version: Any Windows Container
• Remote Extension/Connection Type: Docker

Steps to Reproduce

1. On a Windows 10 computer, enable Windows Containers.
2. Check if Windows Containers are working correctly, e.g: docker run -it -v c:\Users\<my-user>:c:\Workspace mcr.microsoft.com/windows/servercore:1809 Powershell
3. Try to configure .devcontainer/.devcontainer.json:

{
  "name": "vscode-wincontainer-test",
  "dockerFile": "Dockerfile",
  "context": "..",
  "workspaceMount": "source=${localWorkspaceFolder},target=c:\Workspace",
  "workspaceFolder": "c:\Workspace"
}

.devcontainer/Dockerfile:

FROM  mcr.microsoft.com/windows/servercore:1809
SHELL ["Powershell", "-Command"]

I have tried a few path variations such as \\, as well as using Unix paths (/), but none would work.

Does this issue occur when you try this locally?: Yes
Does this issue occur when you try this locally and all extensions are disabled?: Yes

Hey, just FYI, looks like windows containers aren't supported:
