You probably have been in a situation where you finished your task and ready to create a pull request, but for whatever reason you don’t want your changes to get through (For example, you want to merge your changes back into the main branch after the current release). A common behavior – or let’s say old fashioned way – is to put something like “DO NOT MERGE” or “WORK IN PROGRESS” in the pull request’s title. And as an unwritten rule you should write it in all caps :). In such a situation, you can draft a pull request instead of creating a pull request.
To Draft a Pull Request in Azure Repos, you need to choose “Create as draft” when you want to create a pull request.
If you look at the list of pull requests now, you will see your pull request marked with “Draft” token.
