Developer productivity is not just about maximizing your speed in editor. It also includes additional software to help you be more productive. Below is some of my favorite Windows software that I use.
LastPass - Password Manager. Remembers passwords so you don’t have to. Auto log you into web sites, store secure notes, wifi passwords, etc. Web interface and desktop is free. Mobile device application
is premium version at $12 per year.
Pocket - Save web pages/rss feed articles for later and view when ready including offline. Way better than keeping a ton of bookmarks around that you never get back to.
Linqpad - Scratchpad for .NET. Rich formatted output. Intellisense. If you are a .NET program this is a much have application. Well worth the small amount of money to get the license to use the Intellisense.
Visual Studio Code - great all around text editor and development environment. Focused on code first.
