  • VSCode Version: all versions, tested also on latest: 1.4.0-insider 50a0945
  • OS Version: OS X 10.11

Steps to Reproduce:

  1. Create a TypeScript file with a .js extension
  2. Change the language mode inside VSCode to "TypeScript" (defaults to JavaScript in files with a .js extension)
  3. Add some TypeScript specific code, e.g. interface ABC {}

Causes an error:

'interface declarations' can only be used in a .ts file.
