system.diagnostics wcf tracing does not show the service end point that raises an exception

I have added system.diagnostics wcf tracing to my window service that hosts couple of wcf end points.
Because this is a production service i have reduce the 'switchValue' to "Error, Critical, Warning" in order to avoid huge trace files. The problem is that now when I get an exception in the trace there is no reference as to which end point had raised the exception.
Example for such an entry in the trace file bellow.
Thanks

WCF throwing before sending response to client

I have a WCF service where IGameServices contains:
[ServiceContract]
public interface IGameServices
{
[OperationContract]
DtoReturnedMessage<DtoGame> GetGame(Guid gameId);
}
AdminServices contains:
public class AdminService : IGameServices
{
private readonly BoGame _boGame = new BoGame();
public DtoReturnedMessage<DtoGame> GetGame(Guid gameId)
{
return _boGame.Get(gameId);
}
}
I have that BoGame, which is a class with business logics.
My config is:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IGameServices" sendTimeout="00:05:00" />
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:50380/Services/Implementations/AdminService.svc"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IGameServices"
contract="IGameServices" name="BasicHttpBinding_IGameServices" />
</client>
</system.serviceModel>
When I debug it step-by-step, all the business logics works properly, and throws the exception below when the response should be sent to the client.
An error occurred while receiving the HTTP response to http://localhost:50380/Services/Implementations/AdminService.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

It is weird because I have a method to save some data into the DB, in the same IGameServices, which saves normally and returns the success message as expected.
Does any one know what that can be?

I solved the problem. The error was too generic, actually. The issue was with build versions of Postsharp not matching.
I found it out by trying to open the services directly on the browser. I removed Postsharp in that project and BANG.

WCF Communication Exception During Server Call

I'm taking a shot in the dark with this one but I've been experiencing an issue that I'm hoping someone might have come across before...My client makes a server call which pretty much just grabs data from a Sql server DB and returns it to my client however sometimes the client never receives a response from the Server. I put a bunch of logging in and the very last line of server side code is executed but still, the client never receives the response and as a result gets stuck "PROCESSING"... I added a WCF trace and monitored it using the Service Trace Viewer.
And I'm seeing exceptions in the Activity logs that contain the following text:

I don't suppose anyone has seen something like this before and can give me some recommendations as to how I can go about fixing it? Any information would be greatly appreciated.
Thanks!

A CommunicationException with an error message like "The socket connection was aborted. This could be..." is just a general failure condition and is the side-effect of the actual error.
To find out what the actual error is, use your WCF trace output. Select the items marked as Exceptions and look at the details pane for those. One of them will most likely give you more explicit information as to the error - which really could be anything from what you've provided so far.
Establish tracing on both the client and server, and when you see an exception in the trace window, highlight it to show more details in the right-hand-side panes.

WCF Error while receiving the HTTP response to my service

Hi guys I created a service using WCF but when I test my services some completed successfully why some is giving me the error below. Any Idea on how to solve these ? Thanks
An error occurred while receiving the HTTP response to http://localhost:8733/PortOperation/Operator_Service/ws. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

There are many scenarios when this type of error occurs.
First
Check that have you provided proper [DataContract] and [DataMember]? if this is not provided then this type of error occurs. You have to write [DataContract] above the class which you pass in response, and write [DataMember] above the class member which goes into the client response.
eg.
[DataContract]
class Program
{
[DataMember]
public string Example{get;set}
}
Second
Check in the response if some minvalue of Data type is passed. That means some time data member is not initialized at that time it takes the minvalue.
e.g. minValue of int is '-2147483648' so at some time it cannot be serialized and throws an error.
If you want to trace this type of error then add the following code in your server-side web.config
<system.diagnostics>
<sources>
<source name="System.ServiceModel" switchValue="Information, ActivityTracing" propagateActivity="true">
<listeners>
<add name="traceListener" type="System.Diagnostics.XmlWriterTraceListener" initializeData= "D:\Traces.svclog"/>
</listeners>
</source>
</sources>
</system.diagnostics>
I think it will help you.

I was able to solve the problem.
If you are using EF "code first"-approach and you want access to your data using WCF you should consider not enabling lazy loading using the "virtual" keyword in your poco-class because WCF serialization cannot serialize dynamic proxy data.

Although increasing the timeout on both ends of the wire (BTS and WCF Service) may help avoid the error in some instances, you might just be kicking the can further down the road and you probably need to get to the root cause (does this specific web service call NORMALLY take over 20 seconds to complete?).
It is likely that under high load, or low capacity conditions, that your WCF Web Service cannot keep up with the rate of messages that BizTalk is able to send to it.
Depending on what your WCF Service does, you might look at optimising:
Database
SQL blocking while waiting for locks
DB performance may reduced during admin tasks such as Reindexing Jobs, Backups etc
IIS / ASP.NET
See if requests are being queued
Look at any throttling on the WCF Service side (e.g. MaxConcurrentCalls)
If there is no chance of further optimisation (or scale up / out) on the WCF Service side, you may need to look at throttling the number of concurrent orchestrations (using a variant of a Singleton Orch) or limiting the number of threads on your WCF Send Port Adapter (unfortunately, this will affect all messages, so you might need to split out separate SendHost
Be wary when simply 'maxing out' all of the WCF knobs - settings like maxReceivedMessageSize (or maxBufferSize) ="2147483647" will often result in OutOfMemoryExceptions and / or increase the threat surface area.

You need to change the timeout of the WCF service.
I am not sure if that solution is correct, but it is definitely in the web.config file.

I had similar problem when using SOAP adapter(I'm still in biztalk 2006)
You should try the following :
YourMessage(SOAP.ClientConnectionTimeout) = 900000;
900000 is the default value, so increase it to fit your need, the time is in milliseconds.
If this property does not apply to WCF web services, I assume there is a WCF equivalent for that property.
