Visual Studio Code Review Difference Window

c#, visual-studio

Solution

There should be a button on the toolbar like this one that will let you select the 4 different "diff modes".

You can also use the following keyboard shortcuts:

- `Ctrl+\`, `Ctrl 1` - Inline

- `Ctrl+\`, `Ctrl 2` - Side-by-side

- `Ctrl+\`, `Ctrl 3` - Left Only

- `Ctrl+\`, `Ctrl 4` - Right Only

to change the view.

Problem

When I was doing C# code reviews at first in VS 2012 I was getting a side by side comparison of the old and new code. However now I am getting all code in the same window with red lines for old code and green lines for new code. I cannot find the option to change this back to a difference window. I know this is a simple issue but any help will be greatly appreciated!
