I've variously programmed javascript, Matlab, R, Java, C#, PHP, old ASP JScript, VB, VBA, C++, T/P/SQL, Typescript, etc. Having gotten accustomed to the .NET stack, the type safety, the new open source community efforts etc, I am solidly in the C# (and F# if i can find work in it) camp and would avoid going back to dynamic / scripting languages as much as possible.
VSCode is a great IDE, VSStudio is a beast but still powerful, and I really think Typescript is a great idea. Azure is similarly experiencing pretty solid growth I believe, although I've used it in only limited fashion myself thus far.
You are right though, MS tools still have an enterprise-only perception, so you wont be the trendiest kid in amongst all the hipsters. But with things like .NET CORE and its solid performance, open sourced nature, etc, and with people waking up to the fact that "using json to store all your data structures in a database designed by guys who aren't database engineers could be a bad long term plan" and so instead embracing SQL dbs again (and with cloud hosting providers now providing SQL , MS SQL server moving to Linux hosting, etc) I think/hope that more people keep their options open and consider the .NET stack. It makes me feel productive, and I'd rather build things that work, make money and provide useful results, than endlessly pursue every new trendy thing down the rabbit-hole.
