Error while adding the WCF service

Hi All,
I am a beginner in WCF, So please help me out.

This is my MathService.Svc file

<%@ 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 code

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

<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
<dns value="localhost"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
<behavior name="ServiceBehavior">
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- 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 -->
<serviceDebug includeExceptionDetailInFaults="false"/>

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.
