Debug webservice

[Peter K]

Hi

I have a VS2005 c# solution which includes a webservice and a windows
application which uses the webservice.

How do I "debug" into the webservice from the application?

I can for example debug/attach to aspnet_wp.exe and access the webservice
from a browser - and there I can hit breakpoints in the webservice (but
unfortunately not access the more complex methods in my webservice).

But I can't work out how to achieve the same from my windows application.
Thanks,
Peter

How do I "debug" into the webservice from the application?

On a related note, how would one get a look at the soap packets (request and
response) when using the wrapper classes generated from a wsdl? The wrapper
classes try to hide the conversation and it would be nice to see the
specifics of the question.

And in my case, I'm talking to a web service written in php that doesn't
seem to give proper soap error responses, so I really need to see what's
getting sent back.

Thanks

One options for getting at the Soap message content is to use a "universal"
client such as the System.Net.HttpWebRequest object to send and recieve raw
Soap (see the second post to WebClient generates exception: header must be
modified using ... 6/22/07). If you have a WCF client to your web service,
you can add the following local to the class containing the client object
creation and web service call:

Public Shared results As String

Private Class MyBehavior
Implements ServiceModel.Description.IEndpointBehavior

Public Sub AddBindingParameters(ByVal endpoint As
System.ServiceModel.Description.ServiceEndpoint, ByVal bindingParameters As
System.ServiceModel.Channels.BindingParameterColle ction) Implements
System.ServiceModel.Description.IEndpointBehavior. AddBindingParameters

End Sub

Public Sub ApplyClientBehavior(ByVal endpoint As
System.ServiceModel.Description.ServiceEndpoint, ByVal clientRuntime As
System.ServiceModel.Dispatcher.ClientRuntime) Implements
System.ServiceModel.Description.IEndpointBehavior. ApplyClientBehavior
clientRuntime.MessageInspectors.Add(New MyInspector)
End Sub

Public Sub ApplyDispatchBehavior(ByVal endpoint As
System.ServiceModel.Description.ServiceEndpoint, ByVal endpointDispatcher As
System.ServiceModel.Dispatcher.EndpointDispatcher) Implements
System.ServiceModel.Description.IEndpointBehavior. ApplyDispatchBehavior

End Sub

Public Sub Validate(ByVal endpoint As
System.ServiceModel.Description.ServiceEndpoint) Implements
System.ServiceModel.Description.IEndpointBehavior. Validate

End Sub
End Class

Private Class MyInspector
Implements ServiceModel.Dispatcher.IClientMessageInspector

Public Sub AfterReceiveReply(ByRef reply As
System.ServiceModel.Channels.Message, ByVal correlationState As Object)
Implements
System.ServiceModel.Dispatcher.IClientMessageInspe ctor.AfterReceiveReply
results = vbCrLf
results &= "=====AfterReceiveReply================"
results &= vbCrLf
results &= reply.ToString
results &= vbCrLf
results &= "======================================"
results &= vbCrLf

End Sub

Public Function BeforeSendRequest(ByRef request As
System.ServiceModel.Channels.Message, ByVal channel As
System.ServiceModel.IClientChannel) As Object Implements
System.ServiceModel.Dispatcher.IClientMessageInspe ctor.BeforeSendRequest
Return Nothing
End Function
End Class

The calling code would do the following to invoke this behavior assuming the
service object is name WsClient and you have a Textbox control named
txtResults:

WsClient.Endpoint.Behaviors.Add(New MyBehavior)

''' code to invoke your service goes here

'Display the response from the web servive:

txtResults.Text &= results

''' rest of your code...

Hope this helps!
