I'm having the following problem:
cannot convert from 'MyProject.DataLayerServiceRef.MyDTO'
to 'WCFService.MyDTO'
when i'm trying to call a method from the service to add an object to the database.
The problem is that my servicereference method is given a MyProject.DataLayerServiceRef.MyDTO TYPE while the service method wants a WCFService.MyDTO TYPE
What am I doing wrong here..? I'm new to WCF and simply cannot see what I have done wrong
What I'm trying to achieve is to create a new object client-side and use my wcf service to save it to the database (I have created a EDMX file in the service).
EDIT
now I get a new error..:
System.ServiceModel.FaultException:

I've tried setting the "includeExceptionDetailInFaults", but that doesnt seem to help.. :(
The error occurs in this line of the homecontroller.cs:
AnsatDTO[] list = dls.GetAnsatList();
dls is my proxy and the GetAnsatList() method is a service method
Problem solved by creating a new WCF service from scratch.. :)

I have an internal web site that is secured with Windows Authentication. This works correctly.
Contained in the site I have several methods accessible via Web API.
The intent is to automate the calling of those API methods from a SQL 2008 SSIS job. This is our preferred process so that all scheduled tasks are in one place.
When I call the Web API from the desktop of a user that is in the appropriate AD security group the Web API call works properly but when I try to call the API from the SSIS job I get an access error. I have tried putting valid credentials in the SSIS job but that didn't work, I still get the same error.
What security context is this job running under? Can I add that security context to the AD group and get everything working?
Web API under a different authentication process? Can this be configured in web.Config or on the page itself?
**** Update
I've confirmed that the account I expected is the account that is doing the call.
I have more details on the exact error message being returned:

I have a wcf web role hosted in azure which has methods to add, delete update etc. When I step through the code in vs2012 and call the add method I receive a ProcessGetResponseWebException.
The add method takes a job object as parameter. This is the only method that's causing a problem. Any method that doesn't have a job object as a parameter works fine.
The service uses message security with custom username. This is not the problem as I've removed this and am still having same problem and also the other methods work when security is left in place.
The strange thing is if I install my client as a service and start it it all works fine and there are no problems it only happens when run from visual studio. I've tried this on another machine using visual studio 2010 and it doesn't work on that either.
When I call the add method from vs and then logon to azure virtual machine I can see that IIS is using 100% of the cpu.
The bindings are correct as I've went through them, all message sizes are set to the max, timeouts are set to 10 mins. I've even copied the config from the running service that's working just in case and it still doesn't work.
I changed the add method to take a string as a parameter and it works, so it's something with the job object that's passed but can't figure out what and confused as to why it works when installed as service.
I've enabled intellitrace but that doesn't show any exceptions.
Anyone have any suggestions of what I could try next?

I have a WCF service that works locally and previously worked (prior to minor changes) on a separate server. It now throws an "Unrecognized message version" CommunicationException. What might be causing this?
In troubleshooting I've found that it's happening somewhere within the WCF "magic" on the server before it resolves to use the custom binding defined for it.
The server itself has had some monkeying around done on it lately to add SSL and change host names so I'm wondering if there's something server-specific happening between IIS (7.5) finding the service and my code getting called.
My services inherit from a base class that includes a simple Ping method that just returns success once contacted. This has worked on a all other internal server deployments, but even calling this method now give the unrecognized message version.
Calling code just uses a VS-generated Service Reference to create an instance then call it:
var MyService = new MyNamespace.MyServiceClient();
var result = MyService.Ping();
Update
The stack trace (no InnerException exists) makes me wonder if it's SOAP-related:

Any Suggestions?
A pretty niche case here: We have a load balancer (F5) that also manages the SSL certs. Requests coming in looked to be getting forwarded to the server correctly, but also were redirecting back to itself as well. I'm not network engineer enough to know all the details but it was F5 configuration not WCF.
I am using Visual Studio 2010 & SQL Server 2008 R2. I have created a project to sync SQL Server CE (*.sdf) file to SQL Server using a WCF service.
It is working fine when I have small SQL Server CE file (18 MB) but when I tried to sync using a large SQL Server CE file (38 MB) then an error happens.
I have increased size of many parameters in web.config of the WCF service & app.config of my application.
But the error keeps occurring.....
The underlying connection was closed: The connection was closed
unexpectedly.

Above exception means that there's something unexpected happened due to which connection is closed, and most of the time it's due to some exception on service side which caused to reject the request. You can enable WCF tracing for the service and check the logs to confirm the exception. Most of the time, exception message suggests you what went wrong ;-)
HTH,
Amit
I was recently getting errors like this from a web service when I had not configured it correctly to handle enough data eg: maxBufferPoolSize, maxReceivedMessageSize and the like.
Also if you are sending a large array the service behaviour and endpoint behavior sections of these files may need:
<dataContractSerializer maxItemsInObjectGraph="array size here"/>
as Amit suggested, you should try enabling WCF Tracing. the error you are getting can mean many things happening on the server side.
unless you're building a Windows Mobile app, I suggest you use the newer SqlSyncProvider/SqlCeSyncProvider/SyncOrchestrator combo as well instead of the older SqlCeClientSyncProvider/DBServerSyncProvider/SyncAgent (the same one used by Local Database Cache Project Item)
the newer providers has functionalities around batching if data size is really your problem.
When my ASP.NET WCF service calls another ASP.NET WCF service the following is returned:

Any ideas?
Update 10:12 AM - After looking at this for a while: my guess is the other service doesn't like some of the data we pass to it. I think it's not validating inputs and then throws an exception on a null reference or perhaps a DB query.
PS. Names of components in the last stack trace line changed for security\privacy reasons.
PS. I tried to do a search. I pasted my title into the search box and then clicked on search to the left of the input box. Nothing happened.
I would search the source code of the calling wcf service for the term Failed to establish a backside connection.
I am fairly certain there is no built-in exception message in the WCF stack with that exact terminology.
Once you have found the code which throws the exception then you will be step closer to solving the problem ;)
