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
Mark

One options for getting at the Soap message content is to use a "universal"
client such as the System.Net.Http WebRequest 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.De scription.IEndp ointBehavior

Public Sub AddBindingParam eters(ByVal endpoint As
System.ServiceM odel.Descriptio n.ServiceEndpoi nt, ByVal bindingParamete rs As
System.ServiceM odel.Channels.B indingParameter Collection) Implements
System.ServiceM odel.Descriptio n.IEndpointBeha vior.AddBinding Parameters

End Sub

Public Sub ApplyClientBeha vior(ByVal endpoint As
System.ServiceM odel.Descriptio n.ServiceEndpoi nt, ByVal clientRuntime As
System.ServiceM odel.Dispatcher .ClientRuntime) Implements
System.ServiceM odel.Descriptio n.IEndpointBeha vior.ApplyClien tBehavior
clientRuntime.M essageInspector s.Add(New MyInspector)
End Sub

Public Sub ApplyDispatchBe havior(ByVal endpoint As
System.ServiceM odel.Descriptio n.ServiceEndpoi nt, ByVal endpointDispatc her As
System.ServiceM odel.Dispatcher .EndpointDispat cher) Implements
System.ServiceM odel.Descriptio n.IEndpointBeha vior.ApplyDispa tchBehavior

End Sub

Public Sub Validate(ByVal endpoint As
System.ServiceM odel.Descriptio n.ServiceEndpoi nt) Implements
System.ServiceM odel.Descriptio n.IEndpointBeha vior.Validate

End Sub
End Class

Private Class MyInspector
Implements ServiceModel.Di spatcher.IClien tMessageInspect or

Public Sub AfterReceiveRep ly(ByRef reply As
System.ServiceM odel.Channels.M essage, ByVal correlationStat e As Object)
Implements
System.ServiceM odel.Dispatcher .IClientMessage Inspector.After ReceiveReply
results = vbCrLf
results &= "=====AfterRece iveReply======= ========="
results &= vbCrLf
results &= reply.ToString
results &= vbCrLf
results &= "============== =============== ========="
results &= vbCrLf

End Sub

Public Function BeforeSendReque st(ByRef request As
System.ServiceM odel.Channels.M essage, ByVal channel As
System.ServiceM odel.IClientCha nnel) As Object Implements
System.ServiceM odel.Dispatcher .IClientMessage Inspector.Befor eSendRequest
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.Endpoi nt.Behaviors.Ad d(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!
