Im new to Lightswitch and would highly appreciate if someone could advise on the following.
I have Lightswitch Desktop application and WCF Service application in one solution. I would like to add WCF service to LS Client. Im simply adding new Service Reference, however I cannot access it in my code. LightSwitchApplication.ServiceReferenceName is not found. Is it possible to access it somehow?
Thank you.
First, Add a New Project to the existing LightSwitch project.
Create a Class Library called WCF_RIA_Project.
Delete the Class1.cs file that is automatically created.
Add a New Item to WCF_RIA_Project.
Add a Class called WCF_RIA_Service.cs.
Right-click on References and select Add References to add the following references to the WCF_RIA_Project
System.ComponentModel.DataAnnotations
System.Configuration
System.Data.Entity
System.Runtime.Serialization
System.Web
System.ServiceModel.DomainServices.Server

Hi when I trie to create a client for wsdl service (this one: http://webapi.aukro.cz/uploader.php?wsdl) the "add service reference" in VS 2012 creates a client that has no methods in it.
Ive tried to create a test connection on this service in the wcftestclient app and most of the generated methods are marked as errors with message "This opertion is not supported in wcftestclient because it uses type xy", where xy is some type from the service.
Edit: Ive been trying to do this in a windows store app...
Edit2: Ive just tried to add reference in a "windows class library" project at it works without any problems. "Portable class library" project is no go so far.
Any ideas?
I managed to solve a similar problem by doing the following:
Check your Service Reference. Right-click and "Configure Service
Reference". Uncheck "Reuse types in referenced assemblies" and let it
rebuild the proxies.

I have a windows phone application that has WCF service . It works just fine when adding WCF service reference for the first time . But when I want to update the service reference It does not auto generate the code and I can not access the service any more. Any suggestion please ?
Thanks in advance.
Right-click on the referenced service under the folder ServiceRefernce.
Select Configure Service Reference in the menu to access Service Reference Settings.
Above the list of assemblies, Select "Reuse types in specified referenced assemblies:".
Check in the list "System.ServiceModel" and press OK.
I was trying to copy the functionality of an existing WCF service library to use it as a template for a new WCF service library. Since I was going to cut and paste all the code that I needed, and I didn't want it to create the default service stubs, I didn't start it by using the built-in "WCF Service Library" project template. I just added a new blank project to my solution, using the "Empty Project" template.
I then created two new blank .cs code files to my project to hold the interface and class for my service, and copied/pasted the Interface and Class code from my original WCF service library project, and made the alterations that I needed to make.
The new project compiles fine, however...
1) If I go into the project properties, the "WCF Options" section does not appear, as it does in my original WCF service library.
2) With the original WCF service libary project, I could right-click on it and select Debug->Start New Instance, and it would automatically start it using WCF Service Host. With the new project, if I try that, it says, "A project with an Output Type of Class Library cannot be started directly".
How do I get Visual Studio (I'm using 2012 Professional) to see this project as a true WCF class library, short of starting over and using the "WCF Service Library" project template?
You are missing the ProjectExtensions section from your project file
This is from one of my VS2010 projects.
<ProjectExtensions>
<VisualStudio>
<FlavorProperties GUID="{3D9AD99F-2412-4246-B90B-4EAA41C64699}">
<WcfProjectProperties>
<AutoStart>True</AutoStart>
</WcfProjectProperties>
</FlavorProperties>
</VisualStudio>
</ProjectExtensions>
If I remove it, the WCF Options properties section goes away.
EDIT:
I did a comparison of an Empty project to a WCF Service Library, and found that you also need to add this to your project to get the WCF Options to appear in the project properties
<ProjectTypeGuids>{3D9AD99F-2412-4246-B90B-4EAA41C64699};{F184B08F-C81C-45F6-A57F-5ABD9991F28F}</ProjectTypeGuids>
There is another entry in WCF (and not in the Empty project)
<StartArguments>/client:"WcfTestClient.exe"</StartArguments>
which I'm assuming is needed when you do the
Debug->Start New Instance
There is other stuff that you will need however, such as a reference to System.ServiceModel.
To be honest, I think you'd be better off using the proper WCF Service Library template and cutting out stuff you don't want, rather than trying to figure out what you do need.
I understand there are other similar questions, but I haven't been able to find a working response.
I create the default WCF service from the template [which comes with GetData() and GetDataUsingDataContract()].
It runs fine in the browser.
I have a separate web site to which I add this new WCF service:
I do 'Add Service Reference', enter my URL, the service comes up and I click 'OK' to add it.
Under 'App_WebReferences', I see the namespace of my added service: 'ServiceReference1', with 'References.svcmap' under it, and a couple .svcinfo/.wsdl/.xsd files under that.
No proxy files are created, but <system.serviceModel> element is added to my web.config, with what seems to be proper information.
However, with no proxy, I can't access/call any methods in my service (ie ServiceReference1.WCFMethod1())
I can call svcutil, generate the proxy, add it to my App_Code, and everything works as it should.
My question is, why isn't my proxy being created with 'Add Service Reference'?
Everything is under target framework: .NET Framework 4.
EDIT:
Just created a Console App and added the service reference and it created the proxy.
So the issue is my web site is not creating the proxy...
I had this same problem and found that unchecking Reuse types in all referenced assemblies did solve the problem. However, in my case, I needed it to reuse types from some of my referenced libraries. I found this post, covering a very similar problem. In that post, it references a Microsoft knowledge-base article which describes a fix for the the following issue:
Consider the following scenario:
You create an ASP.NET MVC4 Web API project in Visual Studio 2012.
You add a WCF service reference in the project.
In this scenario, the Reference.cs file for the service reference is empty.
Cause
This issue occurs because the DataContractSerializer class has encountered a type (Newtonsoft.Json.Linq.JToken) that it does not support. In this case, it throws an exception, and then stops generating the service reference.
I wasn't referencing that JSON library, but, based on that bug description, I surmised that one of my referenced libraries must have had a similar problem. I figured that one of the libraries that I was referencing probably contained a type that was not supported by the DataContractSerializer, it was throwing the same kind of exception, and it was therefore failing in the same way.
Sure enough, I found out that, in my case, the culprit was one of my own libraries which happened to include a public proxy for the same WCF service. I suspect it was that public proxy that was causing the trouble. In any case, by selecting Reuse types in specified referenced assemblies, and then selecting all of the assemblies except that one, the service reference automatically generated the proxy classes correctly.
When you are adding a ServiceReference : References -> Add new service reference.
Clik on advanced button and uncheck "Reuse types in all referenced assemblies".
This option sometimes causing errors.
Here is the main issue.
The issue source is when you are not able to find Add Web Reference in your visual studio. If the service is asmx, in my case it wasn't generating proxy class until I found these steps -> click on Sercice Reference -> Click on Advanced -> There you will see Add Web Reference... Provide your service URL hit OK issue resolved.
Hope this helps.
I'm using Visual Studio 2008 and have a WCF client working against a WCF service. They are both located in the same Visual Studio solution. After I've made a change in my WCF contract, I want to update the service reference on the client so that changes made to the contract is also made in the proxy.
My problem is that the proxy code is not re-generated.
When I select to update the service reference, the following happens:
A dialog with the title "Updating service reference 'name-of-reference'" is shown. This dialog has a progress bar.
The progressbar moves and the status text in the dialog is changed to "Updating configuration"
The progressbar moves a bit more, and the status text is chnaged to "Configuration update complete"
The dialog doesn't show the text "Generating \something\" (can't remember the exact wording) which I would expedct.
If I delete the service reference and add it again, the proxy is properly generated. I add the service using the exact same settings as before, so I don't think it's a issue I can solve by changing the service reference configuration on the client.
One thing I suspect may be the problem is that I've renamed the default wsHttpBindings in app.config. I've also renamed the default endpoints. The reason behind this is that I need more than one endpoint and having one named 'some-default-name' and one with my own name is just confusing.
The problem with deleting the service and adding it again is that Visual Studio adds a new binding in app.config (among other things) which should not be there.
Anyone seen this problem before? Anyone knows of a solution to it?
When we have had this problem it has usually been one of these errors:
The size of the contract has increased, and is now so large that the WCF configuration does not allow it to be transferred.
A new class has been added to a WCF Interface and that class is not marked as serializable.
There is a compile error that stops the code from building and it therefore uses the old dll
I've run into this problem with the following conditions:
Our workstations are connected to an Active Directory domain (nearly everything uses Windows Authentication)
The service reference I'm trying to update is hosted on localhost, and is running under IIS Express (so the Application Pool user is running as the developer's personal domain user account)
Another developer has added or updated the reference to the project more recently than me.
The only way I have figured out how to workaround this issue is to edit the configuration.svcinfo file for that service reference (you will need to show all files for the project to see it in visual studio), locate the following section:
userPrincipalName value="user#domain.com"
and change the user to my own domain user. After saving the file, I have no trouble updating the reference until another developer updates the service reference (likely using the same workaround). Unfortunately, I haven't been able to figure out a permanent solution to this issue.
My error was that I forgot to add the OperationContract attribute.
In my case the problem was that the previous developer had added the service reference using his machine name rather than localhost. So when I told Visual Studio to update, it connected to his machine, which did not have the changes. I modified the service reference files and replaced his machine name with localhost and it was able to update the reference.
I had this problem too. Deleted the service reference and recreated it again.
My problem was that I had two methods with the same name. Everything builded fine, but I couldn't update service reference. When I tried to start just the WCF service, the error pops up.
Two easy steps to solve that:
Run Service, then stop it.
Update service reference.
Highlight the service as the active project, F5 to run it in VisualStudio, it will start up in the service test app. Stop debugging. Then try to update your service reference - worked for me.
I know this solution is a bit late, but after trying the posted solutions with no success, this worked:
When you create a WebService, it generates a .dll file that you reference as your service reference. This .dll is (as most know) not recreated everytime you make changes to the .SVC file. You can see this if you go and view the date modified property of the web service .dll file, in my case it was three hours old!
My solution was to make appropriate changes to the service contact, save it, and re-build the project which will cause it to recreate all the .dll's reflecting the changes you made to the service contact file (.svc).
After this, update the service reference on the client app, and the changes are evident.
Spades
I had the same problem. Modified some of the data contracts. Tried to "Update Service Reference" and did not see the change. Dropped and re-added the service. Still didn't see the change when writing code in the client. Opened my client with Reflector and saw the service types had the change! So why was intellisense still showing old properties? Restarted Visual Studio and the modifications finally showed in intellisense.
I had the same problem, this by me it was caused by GIT Merge Conflict, i was missing the following code from my csproj file
<ItemGroup>
<None Include="Service References\<SERVICE NAME>\Reference.svcmap">
<Generator>WCF Proxy Generator</Generator>
<LastGenOutput>Reference.cs</LastGenOutput>
</None>
</ItemGroup>
I have added this onder the line of Reference.svcmap
Another solution to these kinds of problems is if your namespaces get jumbled in referenced projects that both consume the service. So:
ProjectA - Consumes ServiceA
ProjectB - Consumes ServiceA, Has Reference to ProjectA
If you change ServiceA and update ProjectB, sometimes the namespaces can can change to look at ProjectA's version of the service.
