ReSharper

Answer 17

ReSharper is a commercial plug-in for Visual Studio that you see I use in my courses all the time. You don’t need to have ReSharper to take my courses, but having it installed, helps you write code a lot faster with less work.

You can get a free 30-day trial version of ReSharper if you like to use it while watching my courses. Based on Udemy’s policies, I’m not allowed to add the link to ReSharper here. So I leave it to you to download and install it.

If you’re a student or work in open-source projects, you can get a free license.
