2005 - "could not create type 'service'"

Hi Chaps,

Also a newbie to .NET 2.0 web services, so please forgive if totally obvious.

What solved my build error "could not create type 'service'" was changing the Class="Service" in the header of my asmx file to the same as the name of my public class which implements the web service in the .cs file.

i.e. if webservice1.cs contained public class mywebservice ...

in webservice1.asmx I changed Class="Service" to Class="mywebservice"

Thanks for the other tips as well!

I encountered the same problem....n the mistake that i have made was that i didn gave the fully qualified name of the class in my ASMX file.It is to be noted that the ASMX file needs the fully qualified name of the class, including any namespace.

(eg:

<%@ WebService Language="C#" CodeBehind="~/App_Code/Service.cs" Class="MTC.SSO.MTCSSO" %>

where MTC.SSO is my namespace and MTCSSO is my class name.

Hi guys,

I am new to .NET and for some days I've been trying to create a "HelloWorld" web service, and deploy it properly so that it is accessed from an outside client. Creating the code of the service was a piece of cake actually and it works when I click on 'Preview in browser' in the VS's Solution Explorer but when I deploy it on local IIS I get the error that most of you refer to in this discussion. I browsed through your posts but none of the suggestions actually worked out for me. Here is my code:

using System;

using System.Data;

using System.Web;

using System.Collections;

using System.Web.Services;

using System.Web.Services.Protocols;

using System.ComponentModel;

/// <summary>

/// Summary description for SayHelloWorld

/// </summary>

[WebService(Namespace = "http://myspace.org/")]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

[ToolboxItem(false)]

public class SayHelloWorld : System.Web.Services.WebService

[WebMethod]

public string HelloWorld()

{

return "Hello World";

}

}

and my Service1.asmx file content:

<%@ WebService Language="C#" CodeBehind="~/App_Code/Service1.asmx.cs" Class="SayHelloWorld" %>

I followed an MSDN tutorial precisely ( http://msdn2.microsoft.com/en-us/library/87h5xz7x(VS.80).aspx ) for deploying the service and I ended up with an exe file that was supposed to deploy it authomatically to localhost. Only at the end the familiar to you error "Could not create type 'SayHelloWorld'." appears on the screen. I tried removing the namespace that was generated by default, but it didn't work. Could it be because I don't have the Front Page extensions installed or maybe some issue with the version of .NET (I use VisualStudio 2005 and .NET 2.0)? One more thing - there is nothing in the bin folder when I check the my application folder in IIS manager. Is it normal?

Any hints and conjectures are highly appreciated! Thank you in advance!

What worked for me was creating a virtual root in IIS Manager. I was just copying my website (folder containing Service.asmx and App_Code, App_Data) to the IIS created wwwroot. WHat one should do in addition is:

1. open IIS Manager (one way is Start-> Run -> inetmrg)

2. In the left tree, browse to <your computer name>->Web Sites -> Default web sites.

3. right click on default web sites, choose New->Virtual directory.

4. In the wizard that opens ,CHoose some name for your virtual directory, say XYZ, and next select the folder where your website is copied. Suppose your website main file is named Service.asmx

Now point your browser to http://localhost<or computer name>/XYZ/Service.asmx

This is the link your web service clients hsould also use.

Karl,

you are a *#$%ing genius. I added a namespace to my generated class to make it consistent with the overall project. As you suggested I went back and modified the asmx file to point to the class prefixed with the namespace and everything worked fine.

commonsense - there are a multiple solutions to a single problem.

.net sense - There are multiple causes for a single error message
