Before every commit, it pays to look at what you're about to save: which files changed, which lines, and which of those changes are actually going into the commit. Two Git commands answer all of that. This guide makes a small change in a .NET C# project and walks through git status and git diff with their real output, including the one surprise that confuses almost everyone: git diff showing nothing after git add.

A .NET C# project fills up with files that should never be committed: build output in bin and obj, editor settings, and secrets such as .env. The .NET SDK ships a ready-made .gitignore that covers all of them, and one command adds it to your project. This guide adds it, shows what it ignores, and proves a file is really ignored.

Git keeps a history of every change you make to a project, so you can see what changed, when, and go back if something breaks. Three commands turn any folder into a Git repository with its first saved snapshot: git init, git add and git commit. This guide runs them on a real project and shows every line of output.

I changed four lines of a .NET project file, and Git reported 32. The ASP.NET Core Web API template creates its files with Windows line endings (CRLF), even on a Mac, while the dotnet commands that later edit a file save it with LF. To Git, every line of such a file looked different. One .gitattributes file, as Git's own documentation describes, stores every text file with LF and ends the noise.

You do not need a terminal to get code from GitHub onto your computer. Visual Studio 2026 clones a repository in a few clicks, either from the URL GitHub gives you or straight from your GitHub account, and this guide walks through both routes screen by screen.

Seeing Permission denied (publickey) when connecting to GitHub means GitHub could not authenticate your SSH connection with any key your computer offered. The usual causes are an unloaded key, an incorrect remote URL, a key attached to another GitHub account, or an SSH configuration problem.

This guide checks each cause in the fastest order so you can get git clone, git pull, and git push working again.

You logged into Azure DevOps and noticed the Repos option is completely missing from the left sidebar. You cannot clone, push, or even browse any repository. This is most commonly caused by having Stakeholder access level, but there are other reasons too.

A complete walkthrough of generating an SSH key and adding a new SSH key to your GitHub account, then cloning a repository over SSH. Covers macOS, Windows, and Linux with every command you need for passwordless GitHub authentication.

You are new to an organization and your Team leader added you to a project in Azure DevOps. You don't see the Repos option to collaborate with your team members.

Azure Repos is a set of version control tools that you can use to manage your code. Whether your software project is large or small, using version control as soon as possible is a good idea. Version control systems are software that help you track changes you make in your code over time.
