Visual Studio Tips and Tricks: Increasing your Productivity for .NET

Mika Dumont

The .NET team is constantly thinking of new ways to make developers more productive. We’ve been working hard over the past year to take the feedback you’ve sent us and turn it into tools that you want! In this post I’ll cover some of the latest productivity features available in Visual Studio 2019 Preview.

Code Fixes and Refactorings

Code fixes and refactorings are the code suggestions the compiler provides through the lightbulb and screwdriver icons. To trigger the Quick Actions and Refactorings menu type (Ctrl .) or (Alt + Enter). The list below contains the code fixes and refactorings that are new in Visual Studio 2019 Preview. We’d like to give a big thanks to the community for implementing and reviewing many of these!

You can now wrap chains of method calls with a refactoring.
