res.sendFile is not a function Node.js

Question

I am not able to send a HTML file using node.js

So first off this is the error I am getting

Application has thrown an uncaught exception and is terminated:
TypeError: res.sendFile is not a function
    at Server.<anonymous> (C:\Program Files\iisnode\www\test\app.js:4:6)
    at emitTwo (events.js:88:13)
    at Server.emit (events.js:173:7)
    at HTTPParser.parserOnIncoming [as onIncoming] (_http_server.js:529:12)
    at HTTPParser.parserOnHeadersComplete (_http_common.js:89:23)

and my app.js code is

var http = require('http');

http.createServer(function (req, res) {
    res.sendFile('test.html', { root: __dirname });
}).listen(process.env.PORT);  

If I am missing something simple, I am sorry as this is the first node.js program I have made

This specific issue has already been answered, but it's worth mentioning that if you're using "express" version 3.x, the fix could be as easy as switching res.sendFile('path-to-file'); to res.sendfile('path-to-file');

This was the problem in my case. So you can either upgrade the express version (or) change the method name with lower case to fix this issue.
