Microsoft released a free (not open source though) IDE called “Visual Studio Code” or “Code” for short. It has built in code integration the’ve dubbed “IntelliSense” that’s backed by their TypeScript library. Interestingly enough they’ve even released a Linux desktop package.
It seems like Microsoft is trying hard to gain any kind of relevance in the web development space built on the Open Source Software development model — especially in the Nodejs and Angular communities. Building multi-platform tools for web developers is a step in the write direction, but they have a big ditch to dig themselves out of. Any web developer that uses Unix or Linux has to break the association of software quality and Internet Explorer, before really being able to use a Microsoft product for their job.
It my hunch that these products are less for the Unix/Linux converts, but more likely intended for developers already using MS technologies and needing to be developing in either a Unix or Linux environment.
