突然丢失的Visual Studio打字稿Intellisense

Question

I am using visual studio community 2015 writing typescript in a MVC 6 application. Everything was working fine last time, when I opened the solution today typescript lost its intellisense, When I compile using gulp it compiles, but visual studio doesn't want to see anything. when I add the "reference directive" on the top of the files the intellisense work, but visual studio still cannot understand html in react tsx files and highlight the tags with red lines which if you hover on them you see "React is not found"! I wonder what happened suddenly!! I didn't change anything I was just writing ts and tsx files.

Answer 1

This happened with me most of the time. I do these steps when VSCode intellisense doesn't work in my mac:-

1) Command+shift P for opening commandPallete.

2) Search for Reload Window.

Answer 2

Try Reset all settings it will start working:-

Tools -> Import and Export Settings -> Reset all settings
