Sourcemap - names array empty for all files

TypeScript Version: 1.8.34.0 Module System: AMD ECMAScript Version: ECMAScript 5 VS 2015 Update 3

All of my map files have the names array empty. I would expect that to have been populated. This has been an issue with VS2015 with all updates

Code

class HomeIndex {

    someVar: number;

    constructor() {
        this.someVar = 0;
    }

    onLoad = () => { 
    };

    dispose() {
    };

}

export = HomeIndex;

Generated map

{
  "version": 3,
  "file": "Index.js",
  "sourceRoot": "",
  "sources": [ "Index.ts" ],
  "names": [],
  "mappings": ";;IAAA;QAII;YAIA,WAAM,GAAG;YACT,CAAC,CAAC;YAJE,IAAI,CAAC,OAAO,GAAG,CAAC,CAAC;QACrB,CAAC;QAKD,2BAAO,GAAP;QACA,CAAC;;QAEL,gBAAC;IAAD,CAAC,AAdD,IAcC;IAED,OAAS,SAAS,CAAC"
}

Expected behavior: names array should contain values for members and variables Actual behavior: names array empty

This is extremely frustrating. Sometimes it makes it almost impossible to debug the code. I’m surprised this issue is not prioritized.

Is this issue still being actively looked at?
