I have added webservice support to an OLD PocketPc 2002 application written in VS2003. I don't have the ability to choose dynamic path as in VS 2005, which is the best way to switch URL from dev, test and prod environment for this application? Should I create some factory class that read a value from the app.config and return a service reference with the correct URI?

View 1 RepliesI'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 RepliesUsing VB.NET 2008 SP1 on Windows XP Pro SP3:
I am using an existing COM dll that works fine in VB6, on the same development machine. The VB6 app compiles and uses this dll without issue.
I start from scratch to design a new Windows Form application in VB.Net. Then when I try to add a reference to this dll, the reference is added to the references list but the path shows as <The system cannot find the reference specified>. If I select this reference in the list, the properties window shows a blank for both the reference name and the path. At the same time, a reference is added for VBA, and it shows the reference name (Interop.VBA) and path correctly.
I used dependencywalker to find the dependencies for this dll. It has 3: user32.dll, kernel32.dll, and msvbvm60.dll. So presumably I have all necessary dependent files.
I have tried un-registering, re-registering the dll. I have tried the command line switches for devenv.exe to reset settings and to launch in safe mode. I created a new user account to see if it was related.
I have tried picking the dll from the Add References, COM tab and also via the Browse tab to select the file directly. Same result all cases. I also tried putting the dll and msvbvm60.dll in my bin folder.
I don't understand how the reference name and path are missing in the properties window when the reference name is right there in the list and I select the path directly when I added it. There are no other instances of this dll registered.
I tried using tlbimp from the command prompt with verbose switch, I get the error:
System.Runtime.InteropServices.COMException - Error loading library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRAY)). I wish it would tell us what is missing.
It must be registered properly and all dependencies available for it to work in my VB6 app, Re-writing the dll is not currently an option.
Suppose I have a solution containing several projects. I set the compiling path as ..in folder. A reference file xxx.dll is used in project aaa, yyy.dll is used in project bbb etc.
xxx.dll and yyy.dll are stored in c:sharedlls folder.
My question is that if I compile the entire solution, do xxx.dll and yyy.dll are draged into ..in folder automatelly?
I am not clear the purpose of the compiling of the solution exactly.

View 4 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..

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.

Suppose in a solution there are two projects A and B. A is a class library project, B is a console project. I set the output path of project A as ..in elease, after I compiled it, I found it is ture that a created file testA.dll is there. Just curiously I checked the folder ..indebug, it is empty. Likewise, I set the output path of project B as ..in
elease. Okay, then I add the file testA.dll to the project B and run the solution etc..
My question is that after these procedures, I found that testA.dll is also in the ..indebug of project A. And also when I checked the folder ..indebug of B, testA.dll is there as well but nothing in the ..in elease of B. I just want to know the secrets of the build path, I am always confused in the real world because there are several projects in a solution.
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"

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?
We have upgraded our project from Visual Studio 2008 to Visual Studio 2010 without any issues until now. Our project contains a folder call Libraries which contains different versions of Oracle ODP.NET DLL's as well as different versions of Telerik DLL's. Our project contains references to one of the versions of each. The problem is once we remove the reference and re-add it by browsing to the new version, again inside the Libraries folder inside the project, it adds the reference, but to the same version we just removed. We can even copy the DLL to our desktop, remove the reference and add to the new one on our desktop and it still will point to the Libraries folder version???. The only we we can actual change the reference to the new DLL is by manually changing the path in the .vbproj file, which is obviously not going to work for us. The same behaviour worked perfectly in VS 2008. We switch our references quite often, when new versions come out, but also far more often to QA different versions of ODP.NET and Telerik Control DLL's, so manually editing the .vbproj file is becoming quickly cumbersome. If I browse to a specific version at a specific path, Visual Studio should ALWAYS do what I'm telling it to do..
I did some seaching and came across a few other people with the same issue. This better not be as designed and if it's a bug, which I believe it to be, when will it be fixed?[URL]..
i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
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.
