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.

I am new to WCF, I have read where you can Bind to a MSMQ, my question is can you also bind to a remote queue running on a Unix box? If this is possible, how would you define your endpoint (address,bining) and what Binding type and binding configuration do you need to use?
using .NET 3.5, IBM WebSphere MQ on unix the QManager is running v6.0.

I am using Kerberos as the Authentication mode for a WCF Client to interact with an ASMX Web Service. I am using customBinding in the WCF Client. I am getting the below mentioned Fault Exception when I invoke the HelloWorld Method by creating a Proxy using SVCUTIL.
`System.Web.Services.Protocols.SoapHeaderException: Server unavailable, please try later ---> System.ApplicationException: WSE841: An error occured processing an outgoing fault response. ---> System.Web.Services.Protocols.SoapException:

I am developing a clickonce application that talks to the server via WCF. So far it works fine with a WCF service that uses wsHttpBinding to talk to the server.Here's what works so far: -
1. I have a WCF web site named "TotemWCF" that runs on an SBS 2003 server (=IIS V6).
2. The service.svc for this is
<%@ ServiceHost Language="VB" Debug="true" Service="Service" CodeBehind="~/App_Code/Service.vb" %>
3. There is a contract: IService.vb, containing several contracts like
<OperationContract()> _
Function NTVSearch() As totem.NTViewDataTable[code]......
In initial testing I used this for ALL communication, but it seems to me that it's a bad idea to use streaming for simple "Get a value from the database" communication and it seems to be introducing errors into my program. So my question is: - "What is the best way of managing this, so that Function1 goes via one binding, and Function 2 goes via another binding. Do I create separate services at the level of the web site, the contract, the service, or the function?

I am using subsonic in asp.net forms C# and I have an instance where I need to loop through a recordset and for each one call the Database to get specific information from a view about that record.
in this instance it is a venue, loop through and for each venue I show there spend and there budget, but I am at a loss as to how I can say use a gridview, execute more code on each row and then add more columns to that row.
just as an update i have been playing with the idea of something like this:
DataSet ds = new DataSet();
ds.Tables.Add(LinqToDataTable(club.All().Where(x => x.level == 1)));
ds.Tables.Add(LinqToDataTable(ViewBudgetSpend.All().Where(x => x.periodfrom == curperiod)));
DataRelation relation = new DataRelation("budgets",ds.Tables[0].Columns["clubId"],ds.Tables[1].Columns["clubid"]);
ds.Relations.Add(relation);
still working this out though.

I am very new to WCF, I have read a lot and seen several presentations about it. I can get the basicHttp endpoint to work on my server but when i wanted to use https, I found that that endpoint binding doesnt work. I think through my research that the wsHttp binding is what i need. I can get the client to work but the service gives me a few different errors when I try to call the ssl endpoint.
Currently i get the following error:
The requested service, 'https://devwcftestsite.crata.ucf.edu/services/Person.svc/Person' could not be activated. See the server's diagnostic trace logs for more information.
Below I have included the web.config for my service project which is hosted at:https://devwcftestsite.crata.ucf.edu/services the service is called:Person.svc

I have a gridview with empty data template. In this empty data template i have a table(HTML) with 4 columns. When user enters data i want to save this in a datatable temporarily at a button click event.. Again if user wants to add one more rows data that also should be added to the same table where i added previous row data. So now the datatable has 2 rows. Like this he may add any no of rows. What i want is all the rows should be displayed when i bind datatable to gridview..At the click event i am adding 1 row at a time to the datatable

I have a gridview databound to an objectdatasource. Everything worked great until I changed 2 columns from asp:BoundField to asp:TemplateField. These are the UPC column and the Part column. I wanted to show a link button for each of these fields that take the user to another page. Now asp.net expects these two fields to be parameters on the update store procedure. Why is this? How do I get it to not assume these columns need to be passed to the store procedure?
Here is the code for the grid view:

I was wondering if anything special is required to add a .NET web services to the "Services" tab in NetBeans to allow my java app to consume a .NET web service. I go and add my WSDL (simple method, 1 operation, takes a string), and I continuously get a NullReferenceError as below:
java.lang.NullPointerException
at org.netbeans.modules.websvc.saas.model.wsdl.impl.WsdlModel.getServices(WsdlModel.java:65)

[catch] at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:1957)
Is this something common? I'm using Netbeans 6.9.1 and yes, the webservice is a stub that takes a string and displays a static message right now.

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 an existing project with a silverlight3 app. First I created SALESservice.svc.This is working fine. Now I added another TARGETservice.svc to my project and rebuilded my entire project but when I am trying to add the service reference in to the silverlight app I get the following error:
There was an error downloading metadata from the address.verify that you have entered a valid address. I didn't write any code in ISALESservice.svc AND ITARGETservice.svc . I have written in SALESservice.svc.cs AND TARGETservice.svc.cs files.Is this causing error? But for SALESservice.svc it is working. I didn't add any code in web.config file.
