Service Reference Stops Working When Make Changes To WCF Service?
May 26, 2011
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?
I'm having trouble getting my archive service working. The service counts files in a directory and sends a email. Pretty simple. However, it randomly stops working. I debugged the service and found nothing wrong. I also have it writing to the eventlog so that I can use it to determine where it fails It progresses through each function normally. I thought my program was failing at on point, because it was only posting "Email Notification Service is Running". However, I realized it wasn't posting to the eventlog source so I've been playing around with different ways to post the message to the eventlog. Am I missing something from my code below? I'm really scratching my head with this one.
I'm having complications with imlementing a service that uses a timer to send emails. In my code, it stops in GetDocuments() after TisValid() validates the directory path. I tried using a addhandler and threading but neither worked.
We have a server with multiple services written in .Net 1.1 and 3.5 running on a Win 2003 server. Everything runs fine, but when we stop a certain service, an unrelated service stops. I have checked and neither has any dependencies. The service we stop is in 3.5, and the unrelated service that incorrectly stops is in 1.1. We get no error messages, nor event log errors, so we are baffled.Does anyone have an idea as to what may be causing this?
i was trying to make my service act dynamically... i have set time for my service about for 2 min ,if suppose it was doin huge amount of work means it will exceeds that 2 min time limit then we need to check the service condition if work is pending means we need to run that instance until upto finish.
public static void StartService(string serviceName, int timeoutMilliseconds) { ServiceController service = new ServiceController(serviceName);[code]............
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.
I have a solution that has three projects. One is a service, one is a form, and one is a class library. I use the form for debugging, my logic is complete now I would like to just call.
I created a service which monitors a few servers and file shares for exchange. Written in VB.NET 2.The service is installed and running fine(ish) but randomly and without any warning or entries in the event log it stops.Upon noticing it stops (the web front end that it generates stops working) we have to manage ther hosting server to attempt to start it again.If we simply try to restart it, it fails to start with a logon failure.
I have a VB2008 application which can control a windows service i.e. start, stop, pause etc. This runs ok on a Windows XP machine but not on a Win 7 machine (message is - Service error cannot open <service name> service on computer '.') ( if I stop the UAC then it runs ok ). It seems to be a rights issue,
i 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...
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?
I want to make a program that will ask the user to enter the service reference URL in the text box then click a button to add the service reference. how to add and remove a service reference?
I'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();
I got this warning that I don't know what it means.Warning1 The service System.ComponentModel.Design.IInheritanceService already exists in the service container.Parameter name: serviceType00
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:
I'm integrating one of our apps with a third-party provider's web service. I've added the service reference, but when I go to dimension a var as one of their types, the types aren't showing up for me in Intellisense. I'm using VB.NET/VS 2008 on Windows 7 and a 2.0 Framework web site running on local IIS. I have imported System.Web and System.Web.Service in my codebehind. I also made sure to check the "Always generate message contracts" checkbox.Types not showing up for service reference
I am trying to communicate with a Windows service on a remote machine on the network but i keep getting an exception saying the following: "System.InvalidOperationException: Cannot open Service Control Manager on computer 'machine001'. This operation might require other priviledges. ---> System.ComponentModel.Win32Exception: Access is denied.
Is it possible to have a dotnet windows service which monitor other services and upon stop of any service, the monitoring service would be able to start the stopped service.
This is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.
Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.
In the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website. I did this by executing an OleDbCommand with a query and a connection string.How do I accomplish the same thing with the new "Windows Search Service" (Windows Server 2008) by using VB.NET? Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?
I had a problem getting a VB.NET web service client to receive the response object from a Java web service.In the process of posting this question someone from another department volunteered some code written for a similar situation.I couldn't find this anywhere on the net so I'm completing my question to help others out.[code]The web service is Apache CXF with some Spring elements mixed in.
Makeing a service that should call a DLL.. When I run it i a Windows form app it works but in the service nothing happens. no error?? Is there some considers that i have to take care of when calling a DLL from a service app?
Today I was build one Windows Service Application which has the reference to 4 Dll. After building the Release I found that there was one more DLL in addition to the reference I have. I checked using ILDASM and it only showed 4 dlls.What could be the issue ? How I can I check why it is getting unwanted DLL's in Release Folder?
I'm currently trying to call a WCF service dynamically See here, therefore, I'm trying to understand what happens behind, when I add a service reference by the GUI of Visual Studio... What's generated..? An object is created and an implicit reference is created...
Are the references contained in a specific container, a sort of pool?
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?
I am building an application and I am using web services for getting data from a server. It was working fine when I was developing on my XP machine but had to switch to Windows 7. On the new machine I grabbed the latest version of the code using sourcesafe.However, when I try to add a service reference in the solution or update an existing one I get the following error:
There was an error downloading 'http://localhost:52490/Service/CustomerService.asmx'.
