General - Error - Asp.net webservice error

Hai all,
Am a newbie to this group and .net platform.For my flex project I need to with a asp.net webservice.
Am having the most difficult time trying to deploy a web service created with Visual Studio 2005.* I'm hoping that I'm just missing one small detail and that someone can point it out to me.

I have stripped this down to the most basic "Hello World" web service.* In fact, all I did for this was create a new web site, ASP.NET web service
Here are the steps to reproduce:
1) In Visual Studio 2005, create a new web site, ASP.NET
web service and place it in flle
system c:/inetpub/wwwroot/sample and a virtual directory
sample was created in my
IIS 5.1.*When I create the webservice the service.asmx,
web.config, App_Code , App_Data
are created automatically. Ok
2) Then Right click on the service.asmx file in the Solution
Explorer and select View in
Browser.* The webservice runs in asp.net development
server.That works fine
3) Then fire up my web browser and navigate to the web
service.* For example:
http://localhost/sample/service.asmx.

4) Now it shows the following error



What am I missing here .* What do I need to do to get the web service to work * I know that it actually does work from the results in step 2.* I'm missing something ....For my urgent anybody direct me in right way plz?

Thank you for any help with this!
Sorry for long such code.Hope this helps.

Here is my service.cs :

Imports System.Web
Imports System.Web.Services
Imports System.Web.Services.Protocols

<WebMethod()> _

Regards:
quotez.

please use code tags when posting code.

regarding your problem: in step #2 when the browser opens with
the web service, what is the full address? usually the Studio will
use some random port, not virtual directory.

also, if the Service is not hosted in IIS you must have the browser
with the service from step #2 still opened while trying to browse
with other browser, otherwise there will be no server to host it.

Thanks for the kind reply Mr.Shadow.Now i findout the error
