WCF / ASMX :: Add Service Reference Reading Svc File But Not Reading Service?
Mar 10, 2011
I was trying to go through this tutorial:
[URL]
but when I tried to add the service reference to the silverlight app, the Add Service Reference window would show me that there was a service file, but the node wouldn't expand to show the rest of the files that contain the services and what not. I got this error instead:
"An error occurred during the processing of a configuration file required to service this request. review the specific error details below and modify your configuration file appropriately."
"Parser Error Message:There is no service behavior named 'AdventureWorks_WebServer.Service1Behavior'."
"Metadata contains a reference that cannot be resolved: 'http://localhost:55579/Service1.svc'.
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
If the service is defined in the current solution, try building the solution and adding the service reference again."
I have a requirement in which i have a database table which has 4 columns Id,Name,position,city.....now i have a form in which the user will be filling in the id and then the other three columns should auto populate ....now i want a web service which will make a data connection and get the Id from the form and then query the database and get the other three columns..i am pretty new to web services ..can somebody give me some heads up on how to achieve this...let me know if i have to provide more details.
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?
I 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".
I know this is probably a pretty easy thing to do and it is if I can upload the file and store it onto the hard drive of the server. What I need to do is read the text file into memory and then parse through it one line at a time. Anyone have any code that demonstrates that?
I 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 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.)
Thing 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
I have created WCF Application in vs2010 and using it in window application . i have added WCF service reference using "Add Web service Reference" from visual stuio. i want to do it by programming.
I 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.
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.
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.
I have a webservice - called MyCompany.WebService1
I reference this using a web reference in my ASP.net web application.
Theres a method called "GetDeal" in this web service, that returns a "Deal" Object.
The deal object currently looks (for example) like this:
[code]....
This class is in a different assembly: MyCompany.Model
The web service references this assembly.
In my web app, I can call the GetDeal method. This returns Service1.Deal (service1 is just the name of the web reference)
I can access both properties above. I have now changed the Deal class, and added a couple more properties.
However, I can't see these new properties in my web application. I've updated the web service in the web application. I rebuilt the web service several times, tried removing the MyCompany.Model reference and re-addding it etc...
I can't figure out what has changed... This was working - I have changed the model before, and it's updated the reference correctly...
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."
I have built a WCF Service that is being consumed by a Silverlight app. At first I created one method that was very simple:
public String SfTest() { return "SF Test"; }
No poblem. My silverlight app references my service and displays "SF Test" in a textbox. Now I add a method to my wcf service like this:
public List<String> GetTest() { List<String> list = new List<string>(); String a = "a"; list.Add(a); String b = "b"; list.Add(b); return list; }
I update the reference to the service in my Silverlight app and the using statement in my xaml cs page throws an error like the service doesn't even exist although it is there. I am assuming the problem has to do with datatypes or serialization or something like that but it is driving me up the wall. Why can't I consume a simple generic list in my Silverlight app through the WCF service.
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?
<Application architecture>I'm developing ASP.NET Web Application by Visual Studio 2008.(.Net Framework Version = 2.0)I put followin two projetcs in the solution.a. Class library which implements all the buisiness logic for application. (I'll call it "ClassLib" in the followin sentence)b. ASP.NET Web applicatoin which presents UI.(I'll call it "WebApp")ClassLib uses Web Service which located on other server. So, I set web reference in it. Method for url settings for this web reference is "Dynamic".
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
[code]...
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.
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'.
Unable to connect to the remote server
No connection could be made because the target machine actively refused it 127.0.0.1:8000
Metadata contains a reference that cannot be resolved: 'http://localhost:8000/Tasks'.
Could not connect to http://localhost:8000/Tasks. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:8000.
Unable to connect to the remote server
No connection could be made because the target machine actively refused it 127.0.0.1:8000
If the service is defined in the current solution, try building the solution and adding the service reference again.
I have a .net app developed in .net 4.0 version. And I implemented an asmx web service in this. Now I want to call one of the webservice method in another classis ASP application java script function.
Is it possible to run a web service as a particular user/service account in the same way a Windows service can?I have a service account used for connecting to the DB and want to run the webservice under this account as the users using the webservice won't have DB access.The way I see to do it is to include the Impersonate option in the Web.config file, but is there any better way to do this?
