WCF NetTcpBinding - from Microsoft tutorial - getting timeout

I built a project as descripted in this URL:

http://msdn.microsoft.com/en-us/library/ms734784.aspx

I used the app.config version. But using the code-Version does not change anything (the timeout-error still occurs).

To create the ServiceHost I used the following code:

this.serviceHost = new ServiceHost(typeof(Calculator));
// Open the ServiceHostBase to create listeners and start 
// listening for messages.
this.serviceHost.Open();

On the client side I used the following code:

ChannelFactory<ICalculator> factory = new ChannelFactory<ICalculator>("netTcp_ICalculator");
ICalculator communicationChannel = this.factory.CreateChannel();
string test = communicationChannel.GetData(5);

On the last line the program waits one minute, then I get a timeout:

This request operation sent to net.tcp://localhost:8008/Calculator did not
receive a reply within the configured timeout (00:01:00).
The time allotted to this operation may have been a portion
of a longer timeout. This may be because the service is still
processing the operation or because the service was unable to
send a reply message. Please consider increasing the operation
timeout (by casting the channel/proxy to IContextChannel and
setting the OperationTimeout property) and ensure that the service
is able to connect to the client.

The class Calculator and the interface exist. Besides this timeout I get no other error. I set a breakpoint at the GetData 开发者_高级运维method, but the breakpoint was not hit.

I have tried to change the portnumber used for the client from 8008 to 8009, but let the endpoint for the server at 8008. I wanted to test if the client tries to reach the server. Then I get the error that the other side is not answering (EndpointNotFoundException).

When changing the client port back to 8008 I get the Timeout error again.

Is there anything wrong with my code? How can I ensure that the server can reach the client? Client and server are in the same test application.

Thank you for your help!

EDIT:

I have now deleted the app.config settings. And tried to build the server and client by using the sourcecode. To build the server was no problem. But building the client is a problem.

There is no way to call:

CalculatorClient cc = new CalculatorClient(myBinding, myEndpointAddress);

The compiler does not know CalculatorClient.

Can I use the following instead?

NetTcpBinding myBinding = new NetTcpBinding();
myBinding.Security.Mode = SecurityMode.None;

// Create the address string, or get it from configuration.
string tcpUri = "net.tcp://localhost:8008/Calculator";

// Create an endpoint address with the address.
EndpointAddress myEndpointAddress = new EndpointAddress(tcpUri);
ChannelFactory<ICalculator> factory = new ChannelFactory<ICalculator>(myBinding, myEndpointAddress);
factory.Open();
ICalculator communicationChannel = this.factory.CreateChannel();
string test = communicationChannel.GetData(5);

I get again an exception at the last line :(

SOLVED:

Ok, the problem is solved. I needed to call the WCF host initialization via an own thread:

hostThread = new Thread(this.createService);
hostThread.Start();

Now everything works fine!

Thanks for all your help!

You are not adding any endpoints to the service. You did not include the part of the example code that adds the service endpoint:

Uri tcpUri = new Uri("net.tcp://localhost:8008/Calculator");
// Create the ServiceHost.
ServiceHost sh = new ServiceHost(typeof(Calculator), tcpUri);

// Create a binding that uses TCP and set the security mode to none.
NetTcpBinding b = new NetTcpBinding();
b.Security.Mode = SecurityMode.None;

// Add an endpoint to the service.
sh.AddServiceEndpoint(typeof(ICalculator), b, "");
// Open the service and wait for calls.
sh.Open();

Edit: Same goes for your client. You have to specify an endpoint addresses

  // Create a channel factory.
  NetTcpBinding b = new NetTcpBinding();
  b.Security.Mode = SecurityMode.None;
  Uri tcpUri = new Uri("net.tcp://localhost:8008/Calculator");

  ChannelFactory<ICalculator> myChannelFactory = new ChannelFactory<ICalculator>(b,new EndpointAddress(tcpUri));

  // Create a channel.
  ICalculator calculator = myChannelFactory.CreateChannel();

Edit2: I can't currently test this code... Will give it a try tomorrow morning.

Are you using Windows 7?

If so, you likely need to run Visual Studio as an Administrator. UAC will not let you create the service endpoint unless you are a running as an administrator.
