Today I was working on a fairly large class and needed to compare two different areas of code. I’m used to using text editors such as notepad++ and sublime where I would normally just open the file multiple times. It turns out that Visual Studio has a similar feature, although it’s admittedly a lot less intuitive:
– Open the file you want to duplicate and make it the active tab (just click on it somewhere)
– Select window from the menu up the top
– Click New Window
This will duplicate your active tab. To place them side by side simply right click on one of them and then select ‘New Vertical Tab Group’.
