Visual Studio and Visual Studio Code. Because I mainly work on the .NET Stack with things like ASP.NET(MVC, Razor Pages, Blazor) and Xamarin. I use VS Code mainly when I'm doing Web Development stuff like HTML, JavaScript, and CSS.
C# and for web applications, there's ASP.NET (Core or ASP.NET MVC 4/5)
* Visual Studio for debugging
* Unit Testing Tools
* Package manager (Nuget, NPM integrated for front-end if your doing client-side development as well)
A good code coverage tool? well if anyone here knows one...feel free to share :) (testing frameworks as well,I know some but for the purpose of getting info from you guys would be great)
I'm currently a .NET developer using C#/ASP.NET MVC. This year I plan to play around with these things => ReactJS, Xamarin, AWS, Docker, (and hopefully swift)
I know there are a lot of online resource/tutorials that can be found online that are free, though Pluralsight is not free, I would recommend it, you can actually register a Microsoft account at Visual Studio online and get some free courses.
Been coding in C# for several years now, I played with F# and it's fun. question though....do you guys think it will be as a popular as C# or Java? you know "first-class" citizen(if I may say so) when it comes to writing business apps(desktop/web/mobile(xamarin-already supported)). :D
