Azure DevOps Git is a version control system (VCS) offered as part of Microsoft’s Azure DevOps Services. It provides source code management and collaboration capabilities for software development teams, allowing them to track changes, collaborate on code, and manage their application’s source code effectively. Azure DevOps Git is built on Git, a distributed version control system, and provides Git repositories hosted in the cloud.

Here are some key features and concepts related to Azure DevOps Git:

1. Git Repositories: Azure DevOps Git allows you to create and manage Git repositories for your projects. Each repository stores the complete history of your source code and related files.

2. Distributed Version Control: Git is a distributed version control system, which means that each developer has a complete copy of the repository on their local machine. This allows for offline work and easy branching and merging of code changes.

3. Branching and Merging: Developers can create branches to work on new features or bug fixes independently. Azure DevOps Git supports easy merging of branches, including pull requests for code reviews.

4. Pull Requests: Pull requests (PRs) are a mechanism for submitting code changes for review and integration. They provide a way for developers to discuss, review, and approve changes before they are merged into the main branch.

5. Access Control: Azure DevOps Git allows you to control access to repositories and branches. You can specify who can read, write, or administer repositories and enforce code review policies.

6. Integration with Azure DevOps Pipelines: Azure DevOps Git seamlessly integrates with Azure DevOps Pipelines, enabling continuous integration and continuous delivery (CI/CD) workflows. Changes in the Git repository can trigger automated build and release pipelines.

7. Code Reviews: Code review features in Azure DevOps Git allow developers to provide feedback on code changes within pull requests. You can use comments, discussions, and approvals to collaborate on code reviews.

8. History and Blame: Git provides a detailed history of changes to code files. Developers can use tools to explore the history of a file, find who made a particular change, and understand when and why a change was made.

9. Git Hooks: Azure DevOps Git supports custom Git hooks, allowing you to enforce specific workflows and policies when developers interact with the repository.

10. Code Search: You can search for code across repositories to quickly find and navigate to specific code snippets or files.

11. Extensibility: Azure DevOps Git can be extended with custom scripts, integrations, and third-party tools to enhance your development workflow.

12. Integration with Visual Studio Code: Azure DevOps Git integrates seamlessly with Visual Studio Code, one of the popular code editors used by developers.
