How can I consume a WCF Data Service without adding a Service Reference.
For a normal WCF service, we use shared contracts and create proxy at runtime to call the service. Is similar concept possible in case of Data Service?

I want to consume a WCF service in my .NET Core application without adding service reference?
I am able to consume WCF by installing WCF connected service and adding service reference but I don't want to add any service reference.
Please refer to the follow link. It has some minors issues, but is easy to fix.
Calling Web Method Without a Service Reference
if you are using wcf service then you can expose it as a restful service. then you can simply consume it. actully i have been use it for many years and its been really useful.
here you can read more about that: REST / SOAP endpoints for a WCF service
you can create a service proxy using svcutil.exe and use the proxy class as a reference.
here is a sample:
SvcUtil.exe http://www.temperatureservice.com:8080/TemperatureService.svc /ser:DataContractSerializer /s /language:cs /out:TemperatureServiceProxy.cs /n:*,WCF.Client.Proxies.Proxy
It will generate TemperatureServiceProxy.cs file, include this file in your project and create a service client by referencing this file.
I've this WCF service hosted in a Sharepoint 2010 web application. The WCF has been created using the following factory:
Factory="Microsoft.SharePoint.Client.Services.MultipleBaseAddressWebServiceHostFactory, Microsoft.SharePoint.Client.ServerRuntime, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"
As you can see this is creating a REST-type service. Because we needed to consume it client-side via jQuery.
Now we also need to access it from a .NET project (WinForms). I've tried adding the Service Reference in VS but it doesn't find anything. I guess that's because it's not a SOAP service right?
So how can I consume it in C# .NET project without breaking the existing jQuery support?
Yes, Add Service Reference does not work for WCF REST services. You have a couple of options here:
Add another endpoint to your service, a SOAP-based one, so that you'll be able to use Add Service Reference on your client. I don't know exactly what the MultipleBaseAddressWebServiceHostFactory does, but you could look how it creates its endpoint(s) and recreate that in another factory - and then add the additional SOAP endpoint
Another alternative is to share the interface definition (the service contract plus any existing data contracts) between the service implementation and the .NET client. Having that interface you can use the WebChannelFactory<T> to create a proxy to the REST service (like you'd have one for a SOAP service).
I am working on a requirement to know what back-end service contracts are being invoked via a service wrapper (wcf service).
This is a enterprise level service platform where we have created a WCF based service which invokes different different Back-end Service contracts.
The requirement is to know which WCF Contract calls which back-end service contracts.
I have a callback service that is hosted over wsDualHttpBinding. I'm looking to add a client that will poll for the data rather than receive the callback (will be a mobile device using wince for demo purposes). I was curious what the best way to do this is? You cannot create a client proxy using NetCFSvcUtil with a service hosted with wsDualHttpBinding (I understand that), but you cannot host a callback service over basicHttpBinding. I really need the same service hosted over both basicaHttpBinding (clients will poll for data) and wsDualHttpBinding (callback will notify clients of data). Any ideas on the best way to handle this without creating two separate services to host the same data?
What do you mean by two separate services hosting the same data? Do you expect to share same service instance to handle both wsDualHttpBinding and basicHttpBinding requests?
Your current problem is that service interface for duplex communication cannot be used for basicHttpBinding. You have to create second service contract and implement it in the same service. In that case you can expose two endpoints for the service: one duplex with WSDualHttpBinding and one with BasicHttpBinding. Endpoints must have different relative addresses. From the perspective of the client those endpoints are separate services - each of them requires separate client proxy. So unless your service is singleton you will have new service instance for each client proxy. New service instance means no data sharing.
Thera are some possibilities to modify this behavior but it means replacing Instance provider.
I need to upgrade our web services to use WCF instead of ASMX. If the signatures of the web services stays the same, will existing clients that already call the ASMX service have to change anything on their end? Is there anyway to still use WCF but not force them to change anything?
Option 1 :
Using the current ASMX's WSDL, generate the client using svcutil.exe
Grab the generated interface and create a WCF service based on this interface
Output : One new WCF endpoint configured with basicHttpBinding. Clients need to update the URL at which they're sending the messages.
Option 2 :
Refactor your ASMX code. Move all the logic into a separate DLL.
Create a WCF service and use the logic in the refactored DLL.
Output : 2 endpoints, one for ASMX and another one for WCF
If you use the BasicHttpBinding for your new WCF service, and implement the same methods with the same message structure, existing callers should be able to call into this new WCF service without any change on their part.
There's also an AspNetCompatibilityRequirements attribute in order to get around some potential compatibility issue - see the MSDN documentation on it.
