Duplex workflow service, chat, IM application

G'day,

I was following the simple introduction to WWF at http://msdn.microsoft.com/en-us/netframework/ff802403.aspx and I've noticed that a new C# WCF Workflow Service Application project created will then compile and run WcfTestClient.exe.  If I create the VB Version of that same project I get a Browser web page, not the WCF client. Is this a bug in the VS2010 VB bits?  How do I change the project to correctly execute WcfTestClient.exe manually in my VB Project?

I am facing an issue in consuming WCF duplex service (WCF service library) 4.0 in c#.net web application project developed in 4.0 framework.

I have defined a callback contract with one callback function in WCF. When this callback function is called from my service implementation, the client application crashes and closes abruptly.
If i remove the callback implementation from WCF, everything works fine.

I tried changing the framework for client to 3.5 from 4.0 and to my surprise the callback works perfectly. I am not able to get why callbacks are not working in 4.0 framework.

Would appreciate help on this issue! 

Source Code:

Interface:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace WCFDuplexServ
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract(CallbackContract = typeof(IClientCallback))]
    public interface ITemperature
    {
        [OperationContract(IsOneWay = true)]

 I created project as a  WCF Service application and now according to recuriment that needs to be converted as a self hosting application

How can i do this?

Converting WCF service app to Self hosting app?

I have a silverlight application and WCF service all made in VS 2010 , i had hosted my site to web server which contain Window 2008 and IIS 7.0

now the problem is i have another application which is a window application developed in VS2008 , when i try to add the service reference it gives me error

::::

The document at the url http://72.44.172.77/HRDev3/Service.svc was not recognized as a known document type.

The error message from each known type may help you fix the problem:

- Report from 'DISCO Document' is 'There was an error downloading 'http://dev_qa.emspa.com/HRDev3/Service.svc?disco'.'.

  - The request failed with HTTP status 400: Bad Request.

- Report from 'WSDL Document' is 'The document format is not recognized (the content type is 'text/html; charset=UTF-8').'.

- Report from 'http://72.44.172.77/HRDev3/Service.svc' is 'The document format is not recognized (the content type is 'text/html; charset=UTF-8').'.

- Report from 'XML Schema' is 'The document format is not recognized (the content type is 'text/html; charset=UTF-8').'.

Metadata contains a reference that cannot be resolved: 'http://72.44.172.77/HRDev3/Service.svc'.

Due to the distributed nature of a business process it makes sense for a workflow to be deployed as a distributed application. See how Windows Workflow and Web Services hold the key.
