es6 intellisence vs2015 support
Чтобы убрать подсветку ошибок es6 в visual studio нужно скачать дополнения для vs node.js tools ,
In VS2015 Update-3 and NTVS 1.2 installed, simply setting TypeScript Editor as the default editor for file extension jsx did the trick for me.
1) Open Tools>Options>Text Editor>File Extension.
2) Type jsx in Extension, select TypeScript Editor as Editor, and click Apply.
