I am a beginner in WCF, So please help me out.
This is my MathService.Svc
<%@ ServiceHost Language="C#" Debug="true" Service="MathService" CodeBehind="~/App_Code/MathService.cs" %> IMathService.cs
file which is the interface code
public interface IMathService
int Add(int a, int b);
This is my MathService.cs
public class Service : IMathService
public int Add(int a, int b)
return a + b;
When i try to add this service to a console application, i get the below error
The type 'MathService', provided as the Service attribute value in the ServiceHost directive could not be found.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.InvalidOperationException: The type 'MathService', provided as the Service attribute value in the ServiceHost directive could not be found.
In the Web.config file I have changed the config file as <system.serviceModel>
<service name="MathService" behaviorConfiguration="ServiceBehavior">
<!-- Service Endpoints -->
<endpoint address="" binding="wsHttpBinding" contract="IMathService">
Upon deployment, the following identity element should be removed or replaced to reflect the
identity under which the deployed service runs. If removed, WCF will infer an appropriate identity
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
Please let me know what is this error popping up.I am using .Net framework 3.5 and VS 2010.
When i try to run the Default service i.e. Service.Svc it works fine.
