WCF service selfhosting - wcf

Question

I am creating a WCF service with self hosting. I have found the following error i.e.:
The target assembly contains no service types. You may need to adjust the Code Access Security policy of this assembly.
The codes are as follows:
namespace MyJobs
{
public interface IJobsSvc
{
[OperationContract]
DataSet GetJobs();
[OperationContract]
Job GetJobInfo(int JobId);
[OperationContract]
List<Job> GetAllJobs();
}
}
namespace MyJobs
{
[DataContract]
public class Job
{
[DataMember]
public int JobId { get; set;}
[DataMember]
public string Description{get;set;}
[DataMember]
public int MinLevel { get; set; }
[DataMember]
public int MaxLevel { get; set; }
}
}
namespace MyJobs
{
public class JobsSvc:IJobsSvc
{
#region IJobsSvc Members
public System.Data.DataSet GetJobs()
{
string str = #"data source=PERSONAL-659BE4;database=practice;integrated security=true";
DataSet ds = new DataSet();
SqlConnection cn = new SqlConnection(str);
SqlDataAdapter da = new SqlDataAdapter("select * from Job1",cn);
da.Fill(ds);
return ds;
}
public Job GetJobInfo(int JobId)
{
string str = #"data source=PERSONAL-659BE4;database=practice;integrated security=true";
SqlConnection cn = new SqlConnection(str);
SqlCommand cmd = new SqlCommand("select * from Job1 where JobId="+JobId,cn);
cn.Open();
SqlDataReader dr = cmd.ExecuteReader();
Job obj = new Job();
if (dr.Read())
{
obj.JobId = JobId;
obj.Description = dr[1].ToString();
obj.MinLevel = Convert.ToInt32(dr[2]);
obj.MaxLevel = Convert.ToInt32(dr[3]);
}
else
{
obj.JobId = -1;
}
return obj;
}
public List<Job> GetAllJobs()
{
throw new NotImplementedException();
}
#endregion
}
}
The app.config file is:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
<compilation debug="true" />
</system.web>
<!-- When deploying the service library project, the content of the config file must be added to the host's
app.config file. System.Configuration does not support config files for libraries. -->
<system.serviceModel>

<behavior>
<!-- To avoid disclosing metadata information,

<serviceMetadata httpGetEnabled="True"/>
<!-- To receive exception details in faults for debugging purposes,

to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="False" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>

Answer 1

You need to add [ServiceContract] attribute to your IJobSvc interface
Update
Create the behavior to expose the metadata.
<serviceBehaviors>
<behavior name="SimpleServiceBehavior">
<!-- 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" />
</behavior>
</serviceBehaviors>
Then configure your service with this behavior:
<service name="MyJobs.Job" behaviorConfiguration="SimpleServiceBehavior">
<endpoint address="" binding="wsHttpBinding" contract="MyJobs.IJobsSvc">
