Am using silverlight4.0 and using the WCF service and my functnalities are working fine and at some point of time am getting an exception as like "The remote server returned an error: NotFound." this was inner exception message and the response status code is"System.Net.HttpStatusCode.NotFound".can anyone help for this ..Thanks in advance.
The problem is that silverlight always shows not found error in many cases, the first thing that can be is that service really not available, second try to make sure that you service function is not throwing exception
Try opening the wcf service in the browser,
also this can help to investigate problem
And here is how you can configure to send real exception to client

I am trying to create a WebSocket client through WebSocket4Net with port 4503.However i could see the the WebSocket status only as "Connecting" as it is neither raising any exceptions nor proceeding further.I was able to throw the Exception OnError Event which states that
"An attempt was made to access a socket in a way forbidden by its access permissions"
Am i missing anything?. Any suggestions or link will be much helpful.Thanks in advance.
ws = new WebSocket("ws://localhost:4503/WSServer");
ws.Opened += new EventHandler<EventArgs>(ws_Opened);
ws.Open();
I've been getting this kind of error today with a different type of socket library. This may be an access permissions problem in Silverlight, but on the server side, I found that I had to shut down Visual Studio, and then launch it with admin permissions in order to start up the service. It's going to be something like that. If it is a Silverlight access permissions thing, you will want to try running it out of browser and turning on elevated trust.
I have to following problem. In my application I used a service reference to a non-WCF service from some external company. I created a proxy class using svcutil.exe tool. Everything worked fine for about a year.
Yesterday however, clients reported that it's not possible to get any response from the service. I figured out that the error returned from the service was:
The formatter threw an exception while
trying to deserialize the message:
There was an error while trying to
deserialize parameter
http://serviceurl:someResponse. The
InnerException message was 'There was
an error deserializing the object of
type specificType
So, what I did I firstly updated the service reference and also generated the new proxy using svcutil.exe. The problem still occurs.
I resolve the problem by using either 1) wsdl.exe tool to generate proxy class 2) add web reference (which behind the scenes using wsdl.exe tool internally to create proxy).
My question is : Why everything worked fine for a quite long time even if I used a service reference? How can I checked whether has something changed in the web service? Any help would be appreciated.
Contact the company that provides the web service and find out what changed.
I have one user who gets the following error when trying to login, "Silverlight client load operation failed for query "Login". [GenericParameterNotValid]". The odd thing is that other users are able to login without issue and I can login using the "problem" account from other machines.
At this point I think it's got to be a client side configuration issue.
My next step is to confirm the Client Side Silverlight Version, but I don't know where to go after that.
Do you have any suggestions?
Install Silverlight Developer runtime on the client to get more details on the error.
Try deleting the user's profile.
This thread might help you.
Just leaving a breadcrumb here. We had the following error in a Silverlight RIA Services application attempting to login:
Load operation failed for query 'Login'. Error in deserializing body of the request message for the operation 'Login'. The OperationFormatter could not deserialize any information from the Message because the Message is empty (IsEmpty = true).
This was in Server 2003 with IE 8. Turns out a restart of the browser made the problem go away! Very frustrating.
I am implementing a WCF based solution and all was working fine until I started to process larger quantities of data.
The Solution worked well in DEV where we added large quantities of daata when we restored the site to QA we got this error . Error rendering Councillors Online web part: [The remote server returned an error: (400) Bad Request.]
Can anyone propose a solution to this problem?
Thank you
My WCF web.config looks as follows :
========================================================
This error can also come if you WCF Code return error -- Object reference not set to an *instance of an object*
As you can track through Fiddler
{"Detail":"Object reference not set to an instance of an object."}
As you can also user Log to treas it out
I have a WCF Web application that uses a WCF Class Library.
My project is a WCF Web project and I am self-hosting.
My problem is that all my web service methods hang with:
And "Unable to automatically step into the server...etc".
The error (not very helpful) returned is:
The operation has timed out
When I invoke the same method(s) using the WCF Test Client
I get the correct response and everything goes smoothly.
So, something must be wrong with my web application.
Following up on a similar post, I used the Service Trace Viewer.
I am getting the error:
The message with To
'http://localhost:8731/Design_Time_Addresses/Authentication/mex/mex'
cannot be processed at the receiver, due to an AddressFilter mismatch at the
EndpointDispatcher. Check that the sender and receiver's EndpointAddresses
agree.
After reading a related post, I tried adding:
[ServiceBehavior(AddressFilterMode=AddressFilterMode.Any)]
And recompiling my class library and updating my services to no avail... still hangs.
I have tried adding both my web service and my web project as startup projects but
I am still unable to step into the code. I also have all the appropriate DEBUG attributes
set in Web.config and App.config.
Any suggestions out there?
From my experience the mex/mex error occurs when I update a service reference in Visual Studio. I have come to the conclusion that this is just part of how Visual Studio figures out how to update the web service rere
Without knowing what your configuration looks like, it's hard to say what's wrong. However, why does your URL have /mex twice in it? Are you sure that's right?
