将节点js参考添加到现有的mvc 4项目

Question

我在.Net MVC 4项目中添加了对node.js的引用，但是遇到了这个奇怪的异常，请提出任何解决方案..........谢谢

错误：-

  a reference to 'NodejsWebApp2' could not be added.an assembly must have a 'dll' or 'exe' extension in order to be referenced.

server.js：-

var http = require('http');
var port = process.env.port || 1337;
http.createServer(function (req, res) {
    res.writeHead(200, {
        'Content-Type': 'text/plain'
    });
    res.end('Hello world\n');
}).listen(port)
