VS2015 update3 Typescript 'Invalid module name' Error

There is a very annoy issue after installing Typescript 1.8.x on VS2015.

It shows tons of error like this

Error TS2664 Invalid module name in augmentation, module '../../Observable' cannot be found.

Here is how to get rid of it.

Replace typescriptServices.js in

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TypeScript

with the file in https://raw.githubusercontent.com/Microsoft/TypeScript/Fix8518-U3/lib/typescriptServices.js.

First take a local backup though.
