When I add a service reference to my VB.Net project all of the properties of type DateTime get changed to type Date. The project is ASP.Net using framework 4.0. The web service being referenced is C# framework 4.0. How can I keep this from happening?

Web Service B - Called directly by same Win32 App and a different set of other Web Applications
I'm working on adding a reference to B into A, so that we can use the functionality B provides without rewriting/reintegrating that code manually into A. I have a develop copy of A on my PC that I'm working with, and am calling a test copy of B on a remote server (the test server is accessed over the internet at our hosting provider)I believe to have my code ready for testing, but every time I go to test it on my local copy, I get the following error.No connection could be made because the target machine actively refused it 10.1.X.XX:8080
at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress)
at System.Net.Sockets.Socket.InternalConnect(EndPoint remoteEP)

It fails on the call to oZip.GetCities() with the above error. The IP in the error message does not in any way indicate it's made it out of our local network, it's a 10.* private IP, whereas the test server has a valid live publicly accessible IP.
I need to add functionality to my web service calls so object translation and automatic retries are done and abstracted away.I would usually override the base class to add the extra functionality, but as the proxy methods aren't over-ridable I can't keep the method names the same. The only other option I can think of to do it this way is to use the 'Shadows' keyword to achieve what I want.What other methods do people use to add functionality to their web service proxy classes without modifying the generated classes?
View 1 RepliesI am trying to consume a web service using VS2008.
The code below works in VS2005 but not VS2008 I, suspecting it's to do with WCF. Please can someone help me to solve the puzzle?[code]...
I'm using Visual Studio 2010 and .NET3.5. I've created a WCF service application. I'm including two DLLs that contain the types I'm returning. The first method I wrote works both in WCF Test Client and also in a console application I created to test. When I move on to the next method that returns a generic list of a type. It works great in WCF Test Client, but when I update the service reference it acts as if the service is unavailable. All my objects say can't find reference, and I can no longer see it in the object browser. It's like it just disappears. I can still see it in the Service Reference folder. If I go back to the WCF app and comment out the contract and implementation of that one method it work again. I created a local class very similar to the class I'm using from the dll, and the it works. Is there something I'm missing here? Can someone point me in the right direction?
View 1 RepliesI have a WCF Service, I won't waste anyone's time with copy/pasting a basic implementation here, just imagine it as being the standard "Echo" example you see scattered around MSDN. Let's say I host the Service Library using IIS / a web app. Let's also say I publish the website to varying environments, local, shared dev server, varying test servers, and of course varying live environments. We'll also assume that the WCF gods smiled down upon us and the deployments went without a hitch.
Now I want to write an app (lets say WPF app for some clarity). When the app starts, I want a drop down listing all the available environments. I don't mind hard-coding or supplying (by means of a config file) those environments, but kudos points for linking any articles showing LAN discovery of deployed WCF services?
When the user has selected their chosen environment, I want the app to be able to call a method on the service (in the correct environment). Now I could do this with a big select case/if statement, instantiating the appropriate proxy class for the environment selected, calling out using the proxy class, etc. I could even pass the class around from method to method as an object and then use select case/if statements alongside TryCast/DirectCast to ascertain which environment the provided proxy class belongs to.
I'm bordering on the idea of selecting an environment (none in particular, just one of them) and on the assumption that all deployments/environments have identical code, instantiate the proxy client with the endpoint details of my chosen environment. I lose a form of type safety, but is that ok? Is that the done way?
I have a WCF Service exposing a single contract and operation:
<ServiceContract(Namespace:="ImageSystem")> _
Public Interface IUploadService
<OperationContract()> _
[Code].....
This subsequently leads to stream casting issues, because the generated function allows me to pass a memory stream as an input (which works correctly when passed through to the service), but instead of passing me back a new stream for the response, it attempts to cast the MessageBodyStream received from the service into my memory stream.
This is, in some ways similar to other posts but as you can see, there are no enums involved in my contracts - presence of Enums caused strange proxy class generation is marked as the answer in the similar post.
Is there anywhere I configure the proxy behaviour to use the contracts I've specified? Clearly I'm within a dev/test environment currently, but when this eventually goes to production it will be memory and file streams passed to the service, and the returned stream can be in any format to be honest, I intend to treat it as the abstract stream class. The only way round this I can see right now is to change my in stream to be the same as the anticipated out stream, but surely there is a better way?
I have a class. In that class is a readonly property the returns a List(Of T) in the class. I dont want that list to be changed. I understand that readonly only actually applies to the pointer and not the object being pointed to. That's fine. But how do I stop people from changing the list?

View 1 Repliesi have a WPF application that uses a service reference to a web service.Now i have a GUI component that tracks the progress of this...But i seem to have some sort of bug here, it only occurs on some machines and not often..I start a call with MethodNameAsync and display the progress bar until the matching Completed event occurs.
some times i call 3 different async methods in a row but only the two of them get their Completed event raised so the GUI will be locked and the application has to be restarted.After being totally frustrated a few weeks i found the event AppDomain.CurrentDomain.FirstChanceException, so i hooked up to it and started logging all FirstChanceExceptions..
[Code]...
Fix this temporary by not using async methods and instead using a thread that will call them one by one.. now this is not a elegant solution, i should be able to use the async methods...

View 2 RepliesI'm just a starter in silverlight and WCF. I came across a very good article here by Miguel A. Castro which teaches to add the WCF manually. I have the contract service setup and the only thing I left is to get the data back from the service in the silveright. I have a hard time translate the code to vb.net.
BasicHttpBinding basicHttpBinding = new BasicHttpBinding();
EndpointAddress endpointAddress = new EndpointAddress("/Person.svc");
IPersonService personService = new ChannelFactory<IPersonService>(basicHttpBinding, endpointAddress).CreateChannel();

How should that be written in vb.net?
I've got a service running (well, it doesn't crash), but when I try to add a Service Reference to it, I keep getting:
Metadata contains a reference that cannot be resolved: 'net.tcp://localhost:55555/mex'.
Metadata contains a reference that cannot be resolved: 'net.tcp://localhost:55555/mex'.
If the service is defined in the current solution, try building the solution and adding the service reference again.The pertinent parts of my config file are:
<netTcpBinding>
<binding name="ReliableDuplexBinding" closeTimeout="00:00:10"
openTimeout="00:00:10" receiveTimeout="00:00:30" sendTimeout="00:00:15"

The service must be self hosted.

I'm attempting to consume a HTTP Basic Auth Secured PHP WebService using VB.NET. I've so far managed to get 100% perfect integration by adding it as a Web Reference and doing the following:
Dim Credentials = New System.Net.NetworkCredential("username", "password")
Dim CredentialCache = New System.Net.CredentialCache()
CredentialCache.Add(New Uri(MyWebService.Url), "Basic", Credentials)
MyWebService.Credentials = CredentialCache
MyWebService.PreAuthenticate = True
I can also successfully add the webservice as a 'Service Reference' and this also works fine, as long as i turn off all HTTP authentication on the SOAP server.
My problem is that I can't find any documented means of sending basic HTTP Auth Credentials when using Service References as opposed to 'Web References'
Am I right in my understanding that 'Web References' are a legacy method of Web Service consumption?

View 6 RepliesWe have an asp.net 3.5 web application calling a WCF service. Originally the app used a "Web Reference" to register the service however after having some trouble and burning an incident with Microsoft their solution was to replace the "Web Reference" with a "Service Reference" to the WCF service.
This is great except the problem is that when we create a Service Reference, the method signatures are different than they were when a Web Reference was used.
From what I've read this may be expected, however in our case this would mean some significant changes to the application and of course it was due yesterday...so...
...I'm wondering two things:
Is it normal/expected that method signatures will change based on the reference type? Is there a way to create the Service Reference that will generate method signatures identical to the original Web Reference?

It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.
