Question

Very basic question – but I couldn’t find an answer.
I have got a asp.net web service which is located in an asmx file. This should call a function from a helper library.
Using a different asmx file in Visual Studio everything is working fine – I just had to add the assembly to the dependencies of this project.

Altough I have copied the assembly to the bin subdirectory on the webserver (I think this was what the descriptions I’ve read said) it returns this error message:

Server Error in ‘/’ Application
CS0246: The type or namespace name
`XXXFunctions’ could not be found. Are
you missing a using directive or an
assembly reference?

Description: HTTP 500. Error
processing request.

Stack Trace:

System.Web.Compilation.CompilationException:
CS0246: The type or namespace name
XXXFunctions' could not be found. Are

This is the asmx file I’m using:

<%@ Assembly name="System.Web.Extensions" %>
<%@ Assembly name="System.Runtime.Serialization" %>
<%@ Assembly name="System.ServiceModel.Web" %>
<%@ WebService Language="C#" Class="FCWService.FCWService" %>

using System.Web;
using System.Web.Services;
using System.Web.Script.Services;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;
using System.IO;
using System.Text;

namespace FCWService
{
    [WebService (Namespace = "http://tempuri.org/NumberService")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [ScriptService]
    public class FCWService : System.Web.Services.WebService
    {
        [WebMethod]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
        public XXXFunctions.Data GetData(double length)
        {
            return XXXFunctions.Functions.GetData(length);
        }
    }
}

Any ideas ?

I found out that there was a <%@ Assembly name=”XXXFunctions” %> directive was missing on top the asmx page.
