Michele,

Your webcasts on the WCF are excellent. Thank you very much for making these videos available to us.

I have a question regarding the end points.

I have a WCF service proxy residing in a separate dll (class library project) with end points defined in the app.config file. This dll is referenced from my asp.net web application. I thought I should be able to just instantiate the proxy class and access the service without redefining the end points in my asp.net application web.config file. However it is not working.

What is the reason behind this?

Your help is very much appreciated.

Thanks

Just letting you know the WCF videos seem to be down at the moment.

Michele,

I would just like to say a huge thank you for this awesome 15 part series. I'm going through a major learning curve at the moment and this series has laid a clear foundation in my mind of WCF of which you have answered the key question for me superbly. "Why should I use WCF?"

Thank you so much for your time and effort on this series, you've helped me tremendously.

The link to the webcast is not working correctly (Or is it just me?). Great sessions by the way!!!

Hi Michele,

To my understanding both of them implement ISerializable and IXmlSerializable. So can you please tell me why DataTable does not work with WCF and DataSet does?

The code that I am using is given below.

Thanks and Regards
Vishal Kaushik

/*------------------ WCF Service Code -----------------------*/

namespace TestServiceLib
{
[ServiceContract(Namespace = "http://www.MyWeb.com/TestService/2007/10")]
public interface ITestService
{
[OperationContract]
DataTable GetDataTable();
[OperationContract]
DataSet GetDataSet();
}
public class TestService : ITestService
{
#region ITestService Members
public DataTable GetDataTable()
{
return new DataTable();
}
public DataSet GetDataSet()
{
return new DataSet();
}
#endregion
}
}
namespace TestServiceHost
{

class Program
{

static void Main(string[] args)
{

using (ServiceHost myServiceHost = new ServiceHost(typeof(TestServiceLib.TestService)))
{

myServiceHost.AddServiceEndpoint(typeof(TestServiceLib.ITestService), new NetTcpBinding(), "net.tcp://localhost:8000/HelloService");

myServiceHost.Open();

Console.ReadLine();

}

}

}

}


/*------------------ Client Code -----------------------*/
namespace MyTestServiceClient
{

[ServiceContract(Namespace = "http://www.MyWeb.com/TestService/2007/10")]
public interface ITestService
{

[OperationContract]
DataTable GetDataTable();

[OperationContract]
DataSet GetDataSet();

}

class Program
{
static void Main(string[] args)
{
ITestService proxy = ChannelFactory<ITestService>.CreateChannel(new NetTcpBinding(), new EndpointAddress("net.tcp://localhost:8000/TestService"));

//This works
DataSet ds = proxy.GetDataSet();

//This does not work
DataTable dt = proxy.GetDataTable();
Console.ReadLine();

}
}
}

change text on page to say "replay" instead of "reply"

I am sorry the line in TestServiceHost to add service end point is:

myServiceHost.AddServiceEndpoint(typeof(TestServiceLib.ITestService), new NetTcpBinding(), "net.tcp://localhost:8000/TestService");

First at all I have to say thank you for this great wecasts...

I have seen the 10 first sessions, but the final 5 sessions could not be reached, I was trying to get registered online for them this morning but all of them thrown the same error message:

Unknown Error

I will appreciate any help about.(Or is it just me?)!!!

I really love your webcast on WCF. I can't access it on MS site. It gave me "Unknown Error" inside MS frameset. Can you fix it? Thanks.
