ES6 methods don't work with typescript syntax check

• VSCode Version: 1.6
• OS Version: fedora 23

my current tsconfig.json is

  {
      "compilerOptions": {
          "target": "es6",
          "module": "commonjs",
          "sourceMap": true,
          "outDir": "src",
          "typeRoots": ["./typings/modules", "./typings/globals"]
      },
      "include":[
          "src/**/*"
      ]
  }

let's say I have this:

  Object.assign({});

if I compile the project with tsc --lib es6 or with a gulp task, it works correctly. However, vscode syntax check gives:

  [ts] Property 'assign' does not exist on type 'ObjectConstructor'

the same happens with Promise

@m3l7 thank you for opening this issue. I have confirmed this happens with the latest bits. This is a language service issue. Moving to that repo.

The issue here is that the tsconfig.json as listed above includes no files. The include list includes "src", but then the output directory is "src" as well. the compiler does not want to recompile the files it outputted last cycle, so it excludes the output directory by default. so the net results is no files to compile..

To solve this either:

• use a different outDir
• Do not set outDir at all, by default a .js file is emitted next to its source .ts file
• add an empty "exclude": []

I have logged #11650 to track showing an error message if the compilation included no files.

sorry for the late reply.
not setting an outDir seems to fix. However, setting an outDir different from include array results in the debugger failing to start. (Cannot launch program 'api.ts'; setting the 'outFiles' attribute might help.')
But this seems like a different issue
