I have installed the latest version of TypeScript and also the latest version of Web Essentials. I created a new TypeScript project in VS2012.

If have a `utils.ts`:

```
moduls utils
{
    export function getNumber() {
        return 4;
    }
}

```

And a `app.ts`:

```
/// <reference path="utils.ts" />

alert(utils.getNumber().toString());

```

The JavaScript files are both compiled seperatly. But to get `app.js` to work properly, the compiled source code of `utils.ts` has obviously to be included.

It does work when I run `tsc app.ts -out app.js` in my console, but I do not want to run it everytime manually.

**Why cannot Web Essentials do the for me?**
