Echo Service Sample error

Question

Hi,

This is newbie question –

 

Echo Service sample from Windows Azure AppFabric SDK V1.0 is giving following exception at "host.Open();" line -

 

System.ServiceModel.EndpointNotFoundException was unhandled

  Message=Could not connect to net.tcp://mynamespace.servicebus.appfabriclabs.com:9351/EchoService/. The connection attempt lasted for a time span of 00:00:21.0362032. TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 208.68.143.50:9351.

  Source=System.ServiceModel

 

Below is the code.

  

Any help would be greatly appreciated.

  

Thanks.

  

Config file -

<system.serviceModel><services><service name="Microsoft.ServiceBus.Samples.EchoService"><endpoint contract="Microsoft.ServiceBus.Samples.IEchoContract" binding="netTcpRelayBinding"/></service></services></system.serviceModel>

Hi,

 

We need a bit more of information to diagnose this issue:

 

• Can you post the full stack trace?
• What version of the SDK do you have V1.0 or V2.0?
• What version of the Samples do you have V1.0 or V2.0?
• Are you using a Labs Namespace? Can you make sure you can hit the service registry?

Thanks,

Answer 2

It's working now. Thanks for the pointers Manuel. Issue is resolved when I had added a reference of Microsoft.ServiceBus in the project to from SDK V1.0. If you add a reference from SDK 2.0, it fails because namespace is different -

SDK1.0: http://azureaspnetpocnamespace.servicebus.windows.net/

SDK2.0:http://azureaspnetpocnamespace.servicebus.appfabriclabs.com/
