All about code tracking and management for example, Azure DevOPS branching and merging, Release management, Continuous integration (CI) and Continuous deployment (CD).

Create folders inside Branches in Azure Devops

To manage work, we need to create folders inside Branches. The key folders that can be created inside Branches are;

  • Features
  • Releases
  • Users

The main branch has to be in the root of repository. All working branches can be branch out from man into above folders;

Click on three vertical dots on main branch and create a working branch, feature/shahzad. You will see a folder and branch inside Branches. Very simple.

Here is the reference to article that will walk you through tf.exe and Git working for enforcing permissions;
