No worries. You can enable the PowerShell in the GitHub codespaces because many of us have done it already.

1. Go to your GitHub repository

  Github repository - dev container

2. Open the “devcontainer.json”

Open the file "devcontainer.json".
If you haven't configured the dev container already then configure the new one by selecting the "configure dev container" option under the CodeSpaces. Refer to the below image,

3. Launch your codespace

4. Add PowerShell to the dev container

Go to the devcontainer folder -> devcontainer.json and add the below lines to enable the PowerShell inside your container.

  "image": "",
  "features": {
    "": {}

Rebuild the container,
