code behind -----------------

[WebMethod()]
    public static string LoginFromFacebook()
    {
        return "helloworld";
    }

This is very simple code I have only one web method in my default.aspx file when i am calling the webmethod I am getting response code 200 ok. I investigated using fiddler response is as below HTTP/1.1 200 OK Cache-Control: private Content-Type: text/html; charset=utf-8 Server: Microsoft-IIS/7.5 X-AspNet-Version: 2.0.50727 X-Powered-By: ASP.NET Date: Mon, 15 Aug 2011 09:16:21 GMT Content-Length: 1535

don't know why this is happening. I am expecting only string as response where i am getting whole page's html as response.

there is a problem with web site and web applications in visual studio. you can just put the design code in your aspx file or just use web-service instead of the default.aspx.
