Entering into a new environment always feels lonely and anxiety. It takes time to adjust in an environment and takes time to build and adjust with setting up things. This similar work in IDEs signifies the visual studio integrated development environment developed by Microsoft used to develop computer programs including website, web apps, web services and mobile apps. Let’s grab the top 20 best visual studio extensions, what they are and how they work. Let’s get started!
What are Visual Studio Extensions?
Visual Studio Extensions functions as an add-ons that adds strength to the editor. They enable you to tailor and expand the development environment to suit your workflow or the particular programming languages and tools utilized.
Visual studio supports 36 different programming languages and allows the code editor and debugger to support nearly any programming language, provided a language specific service exists.
Built in languages includes C, C++, Visual Basic.Net, C#, F#, Javascript, Typescript XML,XSTL, HTML and CSS. Support for other languages such as Python,Ruby, Node.js, and M among others is available via plug-ins. Java (and J#) were supported in the past.
