javascript syntax-highlighting intellisense visual-studio-2015 typescript1.5

I have lost the support for JavaScript files inside Visual Studio 2015 after updating the TypeScript tools from version 1.5.3 to 1.5.4.

By support for JavaScript I mean intellisense, syntax coloring and the JavaScript options inside Options menu -> Text Editor.

My js files look like txt files now.

I have already tried many things:

  1. The steps in this answer: Visual Studio 2015 CTP - Javascript support missing
  2. Repair TypeScript Tools
  3. Repair Microsoft Asp.Net and Web Tools 2015
  4. Repair entire Visual Studio 2015

Nothing worked.

Does anyone knows a solution for this problem?

This is a known bug that we have fixed in VS 2015, however you could have been affected if you installed the "Universal Windows App Development Tools" during a specific period of time. We will soon be publishing a KB with the following workaround:

If the “Universal Windows App Development Tools” are still installed:

  1. Go to Programs and Features, select Visual Studio 2105, click Change.
  2. In Visual Studio setup, click Modify.
  3. Deselect the feature “Universal Windows App Development Tools”
  4. Select “Universal Windows App Development Tools” again, and click Update.

If you have already uninstalled the “Universal Windows App Development Tools”:

  • Reinstall “Universal Windows App Development Tools”
  • Or, take the following steps to reinstall the JavaScript project system and language service:
    1. Download the installer for your edition of Visual Studio, e.g. vs_community.exe.
    2. Open a CMD window, and run the following command: vs_community.exe /modify /installselectableitems JavaScript_Hidden /passive

Sorry for the trouble. Hope that helps.
