WCF with SQL table - exposing metadata - sql

Question

I developed small WCF service which takes all records from table. It looks like that:
IService1.cs:
[ServiceContract]
public interface IService1
{
List<badanieCis> GetRecords();
}
Service1.svc.cs:
public List<badanieCis> GetRecords()
{
przychodniaEntities dataContext = new przychodniaEntities();
return dataContext.badanieCis.ToList();
}
And I am getting a message: Failed to add a service. Service metadata may not be accessible. Make sure your service is running and exposing metadata
What I have made after some research was changing markup in svc file for this one:
<%# ServiceHost Language="C#" Debug="true"
Service="Harvesting.Service.HarvestingService" CodeBehind="Service1.svc.cs" %>
But still nothing.
My web.config file:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
</assemblies>

<add name="przychodniaEntities" connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SqlClient;provider connection string="data source=DAREK-PC\SQLExpress;initial catalog=przychodnia;integrated security=True;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />

Answer 1

You are missing service definition in the config file. You need something like:
<services>
<service behaviorConfiguration="..." name="Service1 with namespace">
<endpoint address="..." name="..." binding="wsHttpBinding" bindingConfiguration="...." contract="IService1 with unterface" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
<services>
...
You may use this tool to help with config.
