TypeScript "Compile on save" feature not working in Visual Studio 2015

Question

The "Compile on save" feature isn't working for me after upgrading to Visual Studio 2015. When I make a change to a .ts file in my project and save, the status bar at the bottom of the IDE says Output(s) generated successfully, but the generated .js file doesn't change.

Here's what I've tried:

• adding the following to the root <Project> element in my .csproj:

  <PropertyGroup>     <TypeScriptCompileOnSaveEnabled>True</TypeScriptCompileOnSaveEnabled> </PropertyGroup> 

• checking and unchecking the "Automatically compile TypeScript files which are not part of a project" option in Tools -> Options -> TypeScript -> Project:

  

• double checking to make sure "Compile on save" is checked in my project's TypeScript Build properties:

  

What am I missing?

As a side note, the TypeScript compilation step does work as expected when triggered by a regular build.

For me it was this option in tsconfig.json:

"compileOnSave": true, "compilerOptions": { ... }, 

Restart Visual Studio for this change to take effect.
