Developer expectations...
"... will treat TypeScript as a first-class language, complete with ... code refactoring... developers have come to expect from Microsoft's tools."
Made me laugh. Hollowly, of course. The only way to give VS any real refactoring capability (for C# at least) is to buy and install Resharper.
I cried (inside, obviously) when I returned to using VS (2010) after a break of over 10 years. It seemed like it had hardly changed. VS is so far behind IntelliJ IDEA (from JetBrains, the developers of Resharper) it is like returning to stone slabs and chisels after using a word processor.
