Automate the release of Azure DevOps web extension on azure market place https://marketplace.visuals

Consider below to automate Azure DevOps Extension release:

1. Prepare Your Extension
•    Make sure your extension is properly structured with a vss-extension.json manifest file.
•    Use the Azure DevOps Extension SDK if needed.
2. Install the tfx-cli Tool
This is the official CLI tool for packaging and publishing extensions.

npm install -g tfx-cli

3. Package the Extension

tfx extension create --manifest-globs vss-extension.json

This will generate a .vsix file.
4. Set Up a Personal Access Token (PAT)
•    Go to Azure DevOps > User Settings > Personal Access Tokens
•    Create a token with Marketplace (publish) scope
5. Publish the Extension

tfx extension publish --vsix [your-extension].vsix --publisher [your-publisher-id] --token [your-PAT]

You can also use --share-with to share with specific organizations.

Automate with Azure Pipelines
Create a release pipeline that:
•    Builds your extension
•    Packages it with tfx-cli
•    Publishes it using the CLI and your PAT

steps:
- script: |
    npm install -g tfx-cli
    tfx extension create --manifest-globs vss-extension.json
    tfx extension publish --vsix my-extension.vsix --publisher myPublisher --token $(marketplaceToken)
  displayName: 'Publish Extension'

Make sure marketplaceToken is stored securely in your pipeline secrets.
