i am new in wcf. i am facing this error ServiceHost only supports class service types
.
here i will say i am doing & running my win service & wcf together.
i added windows service project and also add few reference like System.ServiceModel
for wcf in win service project. when i am trying to run wcf service from win service then i am getting error called ServiceHost only supports class service types
i search & got many answer like
ServiceHost host = new ServiceHost(
typeof(subservice.ISubService), new Uri("someuri"));
If this is your usage, change it to use the implemented service class type of ISubService
ServiceHost host = new ServiceHost(
typeof(subservice.SubService), new Uri("someuri"));
If configuring the service in .svc then:
<%@ServiceHost Service="subservice.SubService"%>
Also in you config file, change service name to the service instead of the service contract as:
<services>
<service name="subservice.SubService">
...
other search result also said very similar things to get rid of this problem.
i have no svc file for my wcf service. i have just one file where i have contract and service classes. i also have config file.
namespace SageDataImportWCF
{
[ServiceContract]
public interface ISagePart
{
[OperationContract]
string SageInsertionProcess(string SQLConnectionString, string CountryCode);
// TODO: Add your service operations here
}
public class SagePartInsertion : ISagePart
{
public string SageInsertionProcess(string SQLConnectionString, string CountryCode)
{
}
}
}
namespace SageDataImportWCF
{
public partial class SageDateInsertionService : ServiceBase
{
#region Local Variables
ServiceHost serviceHost;
#endregion
#region Constructor
public SageDateInsertionService()
{
InitializeComponent();
serviceHost = null;
ServiceName = "Sage DataInsertion Service";
}
#endregion
protected override void OnStart(string[] args)
{
string strAdrHTTP = "http://192.168.6.2:11000/SagePartInsertion";
if (serviceHost != null)
{
serviceHost.Close();
}
serviceHost = new ServiceHost(typeof(SageDataImportWCF.SagePartInsertion));
serviceHost.AddServiceEndpoint(typeof(SageDataImportWCF.ISagePart), new BasicHttpBinding(), strAdrHTTP);
ServiceMetadataBehavior behaviour = new ServiceMetadataBehavior();
behaviour.HttpGetEnabled = true;
serviceHost.Description.Behaviors.Add(behaviour);
serviceHost.Open();
}
protected override void OnStop()
{
if (serviceHost != null)
{
serviceHost.Close();
serviceHost = null;
}
}
}
}
<configuration>

here i have pasted all the relevant code and i like to request some one please have a look at my code and tell me why i am getting the error message like ServiceHost only supports class service types
when try to run it from windows service. did i miss anything in code ?
should i have a separate project for wcf class library and another separate project for windows service because i have one project there i have files for wcf & windows service both.
so looking for suggestion like what i need to rectify in code as a result win service can start the wcf service. please help.

Check the definition of the service in the Markup:
Right click on the SagePartInsertion.svc file and select "View Markup".
Make sure the service is the implementation of the interface, like this:
<%@ ServiceHost Language="C#" Debug="true" Service="SageDataImportWCF.SagePartInsertion" CodeBehind="SagePartInsertion.svc.cs" %>
In the past it failed because I was referencing the interface.
