I have created a new "WCF service library" type project. I have created a file for my contract and one file which implements the interface. Both files have the .cs extension.
Please can anyone tell me how can I consume it. I mean where should I add my .svc file
You have to create another project - Web application or WCF Service application (generally it is the same as Web application with some added references). Then you have to reference your service library in the new project and add .svc file. Delete code behind file from newly created .svc file and open markup of that file. Modify Service attribute of #ServiceHost directive. The attribute has to point to your service implemented in library (full name with namespace). Then add configuration to web config.
If you use WCF 4.0 you don't have to create configuration (default will be used) and you even don't need to define .svc file. WCF 4.0 supports configuration based activation.

I use a wsdl file to generate web service with the help of svcutil but it generates class instead of simple int or string parameter for the service contract.
What I did:
I created a WCF Service Application
I created a Console Application then added the service reference to the project
I used svcutil.exeto generate service from thy wsdl and xsd files in console project
Why does it do that and how I can rewrite the wsdl to solve this problem, please?
Most likely you used /messageContract switch in svcutil.
If you added service via service reference, then right click on service->configure service reference and uncheck Always generate message contracts
Ok, so I have implemented my services, created a new WCF service website to host my services in IIS and used svcutil to export metadata to the .xsd and .wsdl files. From these files I generated the service proxy.cs and .config files and added them to the client.
One of my service operations returns a Generic List to the client though. I know how to change the CollectionType of the deserialized DataType by configuring the Service Reference when it has been added from visual studio (Add Service Reference), but how do I change (or set during the creation of the proxy with svcutil(?)) the CollectionType?
There is a switch /collectionType:<type> you can add to specify the type. See the MSDN docs for all the detail.
I have a Silverlight application communicating with the server side through WCF services. Initially I had everything in the main Silverlight application, but now I wanted to factor our some classes to a separate Silverlight Class Library project. This however gave me some odd issues...
I wanted to factor the classes that does the WCF communication out to a separate project. So I:
Created a new project; Silverlight class library
Moved the classes from my Silverlight application to my Silverlight class library
Removed the Service reference in the application as I no longer call it from the app.
Added a Service reference from the class library project.
Now - compiling is fine and I get intellisense for the service stuff in the Class Library, so it seems to be fine. I also updated the service and got the updates in the Class Library.
But when running the application it fails when doing a service call giving the following error:
InvalidOperationException was unhandled by user code
Could not find default endpoint element that references contract 'MyServiceReference.IMyService' 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.
Seems like it can't find the service, but why? I assume there should be no problem to have service references from a Silverlight Class Library as it allows me to add one?
IT can't find any service configuration - where do you have the config for the WCF service? By default, the client app (the EXE) will have a app.config that contains the service endpoints to connect to.
Also by default, class libraries (DLL's) don't have their own configuration but rely on their hosting app to provide the configuration for them.
So all in all - you're probably missing the config for the client endpoint. Most likely, it has been created as an app.config in the class library project, but that's not being used, really - you'll have to move the <system.serviceModel> section up to the main app's config (I'm not fluent in Silverlight, but you'll know where to put it).

I need to add a .svc file to WCF Service Library I have added to a solution (This doesn't have the .svc file). If I specify this file through ad new item (eg test.svc), this is an installer file not the WCF file.
How can I add this file to my project?
Thanks
You cannot add a .svc file to a WCF service library - you need to add the WCF service file to a ASP.NET web site or ASP.NET web application in your solution.
In a web application or web site, you can right click on the project, choose "Add New Item", and then pick "WCF Service" from the dialog. This will add the necessary .svc file to your web site or web app.
The svc file must to be in a web app/web site as a container - it cannot reside in a WCF service library.

Just right click on sub folders and select "convert to Application"
I have a wcf web service and I need to provide the client with the wsdl files.
Previously I used svcutil on the .dll and everything was fine.
However, recently I implemented the factory to Flaten the wsdl file (re: http://wcfextras.codeplex.com/).
My questions is this: Is there anyway of either using svcutil on the .svc to extract the Flattened .WSDL files or maybe somehow hit up the web service when it is running in the local webdev server to retrieve the .WSDL files?
As far as I'm aware, if I was to navigate to my local web dev server (http://localhost:2916/Service.svc?wsdl) and if i was to view source and saved that as .wsdl that this is wrong and would not provide all the relevant information.
note: See below for how the Factory is used in the .svc file....
<% #ServiceHost Factory="CompanyName.ServiceModel.Extensions.Description.FlatWsdlServiceHostFactory" language=c# Service="CompanyName.WebServices.Service"%>
Thanks,
Steven
Yes, you should still be able to use svcutil to extract the WSDL from your service, even if you have an extension installed that will flatten the WSDL.
To download the metadata document(s) from your running service, use this command:
svcutil /t:metadata http://service/metadataEndpoint
You need to point your URL to the metadata endpoint defined in your config, e.g. the endpoint that's defined to use "mexHttpBinding" or "mexTcpBinding" and the "IMetadataExchange" contract.
If you don't have any metadata exchange endpoints defined, you won't be able to retrieve that information, obviously.
