Reviewing Git repositories

While working with Git repositories, you often want to review the changes you’ve made.

Viewing differences in files

You often want to know what you have changed but not yet staged and what you have staged but not yet committed. To find out, you can use the git diff command, which shows the code statements added and removed, also known as the patch.

Let’s see an example:

1. To make it easier to work with the solution and project, open the Chapter03 solution file in Visual Studio or Rider, or open the Chapter03 folder in Code.
2. In the RepoDemo project, using your preferred code editor, in Program.cs, change the message from Hello, World! to Hello, Git!, as shown highlighted in the following code:

   Console.WriteLine("Hello, Git!");
   

3. Save changes to the file.
4. At the terminal or command prompt, show the differences, as shown in the following command:

   git diff
