Typescript internal module not recognized by VS Code

main.ts

/// <reference path="car.ts" />var c = new Car("red");

car.ts

class Car {    color: string;    constructor(color: string) {        this.color = color;        console.log("created a new " + color + " car");    }}

tsconfig.json

{    "compilerOptions": {        "sourceMap":  true,         "outFile": "main.js"    },    "files": [        "main.ts",        "car.ts"    ]}

tasks.json

Kokodoko: I finally found the problem! You have to OMIT the "args" option inside "tasks.json", only then will the arguments in tsconfig.json be used! I found the answer here: github.com/Microsoft/typescript/wiki/tsconfig.json. It says: When input files are specified on the command line, tsconfig.json files are ignored

For further information about Modules, don't forget to have a look at the TypeScript Handbook

To compile several .ts files into one big .js file using a VS Code task, you need to remove the 'args' from tasks.json and add the "out" argument to tsconfig.json

tasks.json

{    "version": "0.1.0",    "command": "tsc",    "isShellCommand": true,    "showOutput": "silent",    "problemMatcher": "$tsc"}

tsconfig.json

{    "compilerOptions": {        "sourceMap":  true,        "out": "myapp.js"    }}

Note:When input files are specified on the command line, tsconfig.json files are ignored.
