Microsoft has released its Azure Repos app for Teams in a bid to entice developers to its collaboration platform a day after competitor Slack upgraded its app developer toolkit.

The Azure Repos app will drop helpful (or annoying) notifications in Teams channels when repos get fiddled with – for example, code being pushed or checked in, or Pull Requests created or updated. Devs can then have a chat in Teams about the content of the messages.
