I am getting this error while loading(adding) it into service References (web client)
The type 'WcfTrial2.Calculation', provided as the Service attribute value in the ServiceHost directive could not be found.
How to resolve it?
How to create an instance of web service without adding web service reference? How to identify the server address/name where the web service is hosted from C# code?
View 1 RepliesI am adding a reference of class library in web service in VS2008 and it is not copying the .config file from class library to web service. I have checked the property "Copy to output directory" of .config file and its value is "Copy Always".
View 3 RepliesI added a service reference via the add service reference method. I can see all of its services in the intellisense but when I run the project and it executes the line where I instantiate the service : MyProjectName.ServiceReferenceName.IServiceReferenceClient
client = new MyProjectName.ServiceReferenceName.ServiceReferenceClient;it throws this error:Could not find default endpoint element that references contract 'ServiceReferenceName.IServiceReferenceClient' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.
when svc.getLookupList(reqobj) will call i get following error.
"There was no endpoint listening at http://rets.newjerseymls.com/rets that could accept the message. This is often caused by an incorrect address or SOAP action."
After moving application to shared hosting I cannot add service reference to .asmx and WCF services that used to work on dedicated server.The error in adding WCF service reference is:

we have an existing ASP.net application that is undergoing expansion. The new functionality is all written in Silverlight 4. As part of that expansion I gutted all the old Linq to SQL and put Entity Framework 4 into place. To do this I created a standard .net Class Library and added my edmx files there. Naturally, the business entities created by this cannot be used in Silverlight. So I created a Silverlight Class Library and added all the business entities to that Silverlight Class Library as linked files. I changed the name space to be the same.
So I have the following assembly / namespaces
Company.Project.Dal.csproj / Company.Project.Entities (.net 4 class library)
Company.Project.Entities.csproj / Company.Project.Entities (SL4 class library)
With this architecture I was able to share my business entities with my SL enabled web services, my asp.net projects, my silverlight projects. Really it's a beautiful thing.
Once this was done I added "message" classes to Company.Project.Dal and again shared them with the other entites using linked files. These messages are things like MyObjectRequest; they are classes that have properties that can set to the ID of the record in the database you want to get, a search string for filtering by last name, first name, etc. (This is in the style of the Web Service Factory if you're familiar with that.)
Finally I turned the whole message into a generic using a base class called EntityRequest

I corrected this error and everything went well for a week until I had to make my first change to the service interface. I added a new operation contract, clicked the handy Update Service Reference on my client and boom.
I have developed the WCF service as follows.
1) Service Contracts in a project
2) Data Contracts in a project
3) Finally adding the reference of service contract project in a Hosting project (Console Application) with complete configurations.
I am adding one more windows app project as a client.When i am trying to add the service reference using the address "http://localhost:8000/Tasks", VS 2008 displays the below error.
There was an error downloading 'http://localhost:8000/Tasks'.

I have a WCF service which has 4 Operation contracts.
I have added a new contract and it gets the data from database and returns the result set.
I can access the new contract and the service get the correct result set. But while passing the result set to the client I get the error of The underlying connection was closed: The connection was closed unexpectedly.
What are the steps to follow after adding a new contract like new binding etc.
when i am adding service reference the Following erro shows Up..where as the same works on the Other machine. The url when tested in Internet explorer works but only while adding shows the error. The request failed with HTTP status 403: Forbidden. The HTTP request was forbidden with client authentication scheme 'Anonymous'.
View 5 RepliesI could really use some help on this one. I've been fighting it now for several days and we are supposed to start testing early next week.I am subscribing to 4 web services all hosted by the same company. The integration with 1, 2 and 3 all went fine, but on the fourth I keep getting the very unhelpful error:
System.Web.Services.Protocols.SoapException = {"Server was unable to process request. ---> Object reference not set to an instance of an object."}

I'm currently trying to work out the best way to build this web application, which will then be intergrated on other systems, such as WinForms, Intranets etc.
We hope to include the usual layers i.e. DAL, BLL, BOL and UI but I have been experimenting with Entity Framework 4 and WCF Data Services and managed to get something in place where I was using WCF as a gateway to EF4.
i.e. Adding a Service Reference to my project and then using the EF4 context and writing LINQ queries against the DB
e.g.[Code]....
Now with the current setup I would still need to write a DAL Class Library, that interacts with the Data Service, because as I said WCF Data Services only seems to be a gateway, I can't see where to put the code (above) in the Data Service and then how I could these methods.
My questions are: 1. How do I develop a WCF Data Service in such a way to allow this behaviour - I know how I could do it using ASMX web service, something like [Code]....
2. If I am to use WCF Data Services, how is serialization handled (if at all) - again I know how to do something in ASMX web services
3. Again, If I am to use WCF, how do I add Security and only allow my applications to access the web service - for obvious reasons
4. Would it be possible / logical to also include the Business Logic Layer into the web service?
How do I add the WCF service built using VS2010 as a service reference to a Winforms app which is written in VB6?
View 1 RepliesI am trying to call web reference "A" in an application.
The web reference "A" will then call a function in another web reference "B" through HTTPS connection (require certificate).
Then I keep getting the following error:

I want to add web service reference but we are using proxy. Is there a way to bypass proxy and add web service reference?
View 1 RepliesI have a UI that communicates with a service. I made some changes to the service- added some code and a property in the Interface associated with the service. After I made the changes, I updated the service reference in my UI and I couldn't access my newly added property. I also tried deleting the reference and adding in back again, it still doesn't work. I get the following error:
xxxxxxx(filename) does not contain a definition for xxxx(propertyname) and no extension method accepting a first arguement of type xxxxx could be found(are you missing a using directive or an assembly reference?)
When I look in the Reference.cs file, I don't see the newly added property in it.
I have developed an asp.net web service and deployed it Win 2003 server on IIS 6. I tried to access it from my asp.net application which is in developer pc, i'm getting a dialog-box "Discovery Credential for Proxy Server"... which asks for a user and password.
Even when I provided right credentials it is not accepting. May be this is because of firewall. How can I get rid of this.
I have a number of .Net web sites built in VS2010 using Framework 4.0that reference a web service to send emails.
My most recent site I created as a web application as opposed to a web site. In the Solution Explorer you can add a 'Service Reference' and, if you click the Advanced button you can then add a reference to a web service.
I did that and now the (web application) site won't build - it says it cannot load the Ajax dll. If I remove the reference to the web service, the site builds okay - if I add the reference back in, the site will not build.
Do I need to abandon the idea of using a 'Web Application' and turn it into a 'Web Site'?
I am getting an error when i try to add a service reference of a WCF service. Error details is below. My web service is hosted on a different server and my client is on different server. When i run the service directly from IE i can see the service but adding it in .net web application i get error.

I have web project and class projects. one of the Class project has web reference. and i am consuming it in web project.Question: can I change class projects web reference url depending on environment DEV, Release, Test?Question: While in runtime why does not web reference's url take value from app.config?(it is taking value from Settings.settings.)
View 1 RepliesThing is, when my service is providing result of type string my client .aspx page is working fine and it gives reference in my code. But now I changed my service to provide custom data type and I can't see service reference in my code, intellisense doesn't offer it at all. What am I missing here? WCFTestClient.exe is giving good results but I can't create my own in VS 2008

View 1 RepliesI am having a strange issue in my C# Console Application:
Name Space: WcfConsoleApp
Main Class: Program.cs
Name Space: WcfConsoleApp.ServiceReference
this namespace contains the WCF service reference
After building the project, the Program.exe avaliable in Debug folder is executing fine as expected.But when i move the exe to Client, where i need to actually run this exe, it works fine up to the line where i am referencing the Service, the line is:
WcfConsoleApp.ServiceReference.ServiceClient service = new WcfConsoleApp.ServiceReference.ServiceClient();
the consoel app crashes on the client machine at this line. (i know this because before this line, i display some mesage on the console)the same .exe and works fine at my development machine.I am sure it has to do some thing with reference path, i think the program is not getting to the path where service reference is avaliable. I have copied the full project folder as it is to the client, but still its is not working.
created a web reference to this web service
http://soap.search.msn.com/webservices.asmx?wsdl
using the VS(2008) Data configuration wizard, and it found the web service and displayed various items from the service. I want to make a simple call to this web service (mainly to learn how to do it). Here is some sample code I found, but I just
don't know how to implement it.
private void Call_Web_Service_Method()
{
ServerName.WebServiceName CallWebService =
new ServerName.WebServiceName();
String sGetValue = CallWebService.MethodName();
Label1.Text = sGetValue;
}
I named my web service reference LiveSearchService. What code do I need to implement, what libraries, to retrieve any information from this web service?
I have an ASMX web service which, in turn, creates a Service Reference which ultimately calls a third party web service. So, in essence, my ASMX is acting as a proxy to the thrid party service. This works fine on my development box.When I deploy to a target server and call my ASMX web service, it fails with an object instance not set error. On closer inspection, it looks as if the failure is in the line of code which creates an instance of the Service Reference - DIM XXX as new ServiceReference.I'm guessing that something has gone missing in the deployment, but can't see what.
