Simple WebService + IIS

Posted on 2013-01-23
Last Modified: 2013-03-07
Hello, I'm trying to make a very simple web service and deploying it with IIS so other machines in my network can access it. I know almost zero about web programming and can't figure out what's going wrong.

Here is my webservice code (the default):
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;

[WebService(Namespace = "")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
// [System.Web.Script.Services.ScriptService]

public class Service : System.Web.Services.WebService
    public Service () {

        //Uncomment the following line if using designed components 

    public string HelloWorld() {
        return "Hello World";

Open in new window

I created it into a Folder (Web Site1). When I try to run it from VS itself I get an error "[No relevant source lines]". When I publish it to "c:\Inetpub\wwwroot" and try to access it via IIS, i get an error "You are not authorized to view this page."

Am I missing a step here?

Thanks in advance.

I suppose this is a web service file (.asmx)? For this to work properly it must be contained in a ASP.NET Web Application. This will not run in any other application type.

You should also ensure that IIS is setup correctly on your local machine if you're using this for testing. Also ensure that your site is configured properly.

 In order to test r-click on the asmx file and select -> view in browser. You should then see a page with the method definition or an wsdl description language.

The WebService technology has now been replaced by the Windows Communication Foundation (WCF).  Therefore (and I've only been learning this myself a few months) I would recommend not pursuing a WebService in the manner you are doing currently.

In VS you can start a new project, then select Templates > Visual Basic > WCF > WCF Service Application and this will give you the code you need which runs perfectly well from the VS debug button.

You can then adapt it to suite your requirements.

You can still use a normal webservice. We're still using it and have been using it for the past few years without any problems.

But I would agree with Rouchie WCF does have lots more benefits.

Cheers @esolve

@toddinho - the main benefit is the WCF provides much better reliability with newer technologies while fully supporting older ones.  This 'just works' facility is priceless when learning as a newbie.  You will probably want to upgrade your .Net framework to 4.5 though as part of this.

Try using aspnet_regiis command to register .net modules.

Yeah, I'm pretty sure it's a permission problem in IIS configuration... I tried the WCF Application and it ran in VS, but when I published it into IIS wwwroot folder i still couldn't visualize it...

In authentication methods I have Anonymous Access ticked and "Allow IIS to control PAssword"

Any ideas how to fix this??

PS: I'm gonna give the WCF a try since i didnt really start to delevop in web service anyway =p

try to create new application pool for this new website

TRy to assign default page for the website

Set the directory browsing settings enabled.

Check whether page is getting opened in IIS through browse option.

Which IIS version are you using?

Three ideas, all fairly basic.
1. Make sure you have the proper .NET frameworks installed.
2. Make sure you have your virtual directory set to the right framework.
3. Run this in the command line to make sure your IIS/.NET permissions are correct.

c:\windows\\framework\v2.0.50727\aspnet_regiis.exe -i

Ok, I used the aspnet_regiis.exe -i (from every framework fodler), but i got the same error...

Im runnning IIS 5.1, VS 2010, Framework 4.0 and Windows XP...

@AkilaPalanimuthu: I checked the forum you posted, I cant find the place in IIS 5.1 to add IIS_WPG permission. Also i Tried to activate Directory Browsing woth no luck.

I actually erased the default files from IIS, I'm trying to visualize the service directly by righ-clicking it and "Browse"...
