I downloaded the solution and the Button did not even have an Event Handler attached to the Click event. Is the solution supposed to work?! :-)
:) sorry about that. there were a lot of codes in my application so that I cleaned them up and I think I accidentally remove the event handler.. :)
I thought you wanted know why response stream is null?
I just removed Astoria stuff and let the Your default [web service] page to return string "AAA" and I got "AAA"
I think IIS 6 should work arlight. if II7 works why not 6?
Yes. I want to know why response steam is null. but I'm not sure why it doesn't work with Astoria. I'm very sure that Astoria service is working fine since I have tested. maybe, HttpWebRequest or HttpWebResponse are missing some features?

Infact, the button click event is hooked in the code. So the button clearly fires click event.
Just to clearify what I did was, since what goes to server and also comes back are json string, I just changed your code to send request to default.aspx page without using Astroia.
Then when I run your app using ASP.NET Development Server, you are right, I was dazzling, because I get NULL response stream. But again if you change Content-Type to something else, you can get response stream with ASP.NET Development Server too.
One thing I notice is that regardless of MIME type, the request still coming through as I see it in the debugger (Default.aspx page gets called)
However with the same thing when that App runs on IIS, It work with application/json MIME type.
I think SL maybe reading MIME type from header when response is returned from server?? Maybe?? And it gives up because you requested json type but it returned OCTET type or something...??
I added this to default.aspx, and manually set content type as suggested by the link I posted ealier. and now I get response stream alright with asp.net development server.
I haven't tried yet. but I mailed to Yi-lun (Microsoft) about this problem. I'm waiting his reply. I hope he will be able to confirm whether this is a known issue or not.
Thanks for your solution too. but it's a workaround, right? Hosting Astoria and SL on IIS instead of cassini, using web handler, using xmlhttprequest wrapper might solve the problem but those are workarounds. I would like to know whether this is my mistake
in my coding or HttpWebRequest & HttpWebResponse
are missing something. What do you say?

Hi Michael,
I added this to default.aspx, and manually set content type as suggested by the link I posted ealier. and now I get response stream alright with asp.net development server.protected override void OnPreInit(EventArgs e)
{
Response.ContentType = "application/json";Response.StatusCode = 200;
Response.Write("{hello:123}");Response.End();
}

In short, answer to this is to
1. use IIS
2. make HTTP Handler or something if you don't have IIS
I gotta go, fat controller is looking for me

Hi Michael,
Have you tried your app in IIS yet?
I am not sure what I suggested was relevant to you,
Anyhow, It would be nice to hear from you if some hours of my study helped you somewhat.

It's good you did that Michael,
It's always good to hear a defnite answer and avoid unnecessary workround whenever possible.
I read your latest blog, that seems a fine solution too.
Thanks for letting me know :-)
