I was getting exception while making a call the my WCF service more larger request XML object content length 65708, where it is working without any issues with request XML file content length less than this.
This is service we are exposed to external clients and I used SoapUI to debug the service and I am getting the exception HTTP/1.1 400 Bad Request[\r][\n] and not even hitting to the debug point. I searched the web and applied the configuration values provided, but none of them helped me to resolve the issue.
After all the config changes, my web.config file is looks like this (only binding part).
<bindings>
<basicHttpBinding>
<binding name="GDASHttp" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" messageEncoding="Mtom" textEncoding="utf-8" transferMode="Streamed" useDefaultWebProxy="true">
<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Windows"/>
</security>
</binding>
</basicHttpBinding>
I didn't changed any settings in the client file as I can getting the exception from SoapUI and issue is related to server configuration only. I do understand the issue with some the settings is accepting according to the file size, but not sure what is maximum values we can provide in the above settings.
I modified the IIS settings as per some of the Google advises in the server and this is my changed applicationhost.config file.
<location path="Default Web Site/GDAS.FY15R2.3.1/Trusted" overrideMode="Allow">
<system.webServer>
<handlers accessPolicy="Read, Execute" />
<security>
<ipSecurity>
<add ipAddress="127.0.0.1" subnetMask="255.255.255.255" allowed="true" />
</ipSecurity>
<requestFiltering>
<requestLimits maxAllowedContentLength="40000000" />
</requestFiltering>
</security>
<serverRuntime uploadReadAheadSize="2147483647" />
</system.webServer>
</location>
This is the value you would use: 2147483647
But for WCF you need to configure that in both the client and the server. You can not just change the Server Binding, as the two Bindings are basically shaking hands so the MAX value should match in both configs.
I would turn on tracing and see exactly what is happening.

I'm having an issue with my basicHttpBinding configuration in web.config file, all configuration was configured through "Edit WCF configration" VS2013 tool, but when I called method in "WCFTestClient" tool it returned:
The maximum message size quota for incoming messages (65536) has been exceeded.
I know that my configuration is OK and it's being ignored because when I open that config "WCFTestClient" tool it shows me different values, default values. Then why MS is offering that configuration if it's being ignored brutally, that's stupid, I guess. But the main question would be, how can I resolve it, or to tell him to take my configuration not his, compiled from somewhere?
P.S my Web.config basicHttpBinding
<basicHttpBinding>
<binding name="BindingConfiguration" closeTimeout="01:50:00"
openTimeout="01:50:00" receiveTimeout="01:50:00" sendTimeout="01:50:00"

maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
</binding>
</basicHttpBinding>
and usage:
<endpoint address="PersonService" binding="basicHttpBinding"
bindingConfiguration="BindingConfiguration" name="PersonSvcBasicHttpBinding"
contract="WebService.IPersonService" />
Usually having both maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" works for me.
I have been battling to resolve wcf issues on our production servers. One of the errors thrown is "The server rejected the upgrade request." among other weird errors I'm receiving. Our applications runs on the Citrix environment for the front end and our application servers host our WCF Services. We have two application servers set up for load balancing and this KEMP server supports sticky ip's since we are using nettcpbinding. However, I am not sure if we have configured our NetTCP settings correctly as the application frequently uses 100% CPU, when more than 5 users log onto an application. After an iisreset, it takes about an hour for this to re-occur. Please find below the configuration of the NETTcpBinding below:
<bindings>
<netTcpBinding>
<binding name="NetTcpLargeBindingEndpoint"

</security>
</binding>

I have tried searching articles for the correct settings to have for nettcpbindng, but not luck and the most helpful is this msdn article:
https://msdn.microsoft.com/en-us/library/vstudio/hh273122(v=vs.100).aspx
Is there something I'm doing wrong in these settings? Please assist
I'm accessing a third party WCF service (I have no access to the service configuration) We're using SSL certificates for the authentication.
I'm getting this error when trying to access to any of the provided methods
The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The
authentication header received from the server was 'Negotiate,NTLM
I checked many google links and no luck so far- No idea what else to check on my side.

Try setting your clientCredentialType="Windows" to clientCredentialType="Certificate" I usually use hard-coded WCF config, not config file, so I'm not really sure on this, but either way, take a look at the following link: Selecting a Credential Type on MSDN.
Good luck. I'm surprised what/whom you're connecting to didn't give explicit endpoint connection instructions, but hey, you deal with every kind when working with 3rd-party stuff.
Ok, this may be a little vague so I aplogise in advance, essentially the server is telling you you are not authorised, normally for this you would add something like the below onto the proxy you generated
svc.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;
where svc is your generated proxy. I have also seen this on a misconfigured IIS hosted endpoint where the virtual folder does not have allow anonymous set (though you say you cannot access the service configuration so that may not be to helpful). hope this helps
edit added more info,
It may be, depending on security, that a setting similar to below may be more usefull
svc.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Anonymous;
Edit 2
The config above shows that the wsHttpBinding you are using has Windows set as clientCredentialtype for the transport security and user authentication, this mean that you will be sending through the credentials of the currently logged on user to the service for authentication using NTLM (as negotiateServiceCredentials is true) have you confirmed that the user logged on has rights on the service?
We have a .Net 3.5 Workflow hosted as a service that sometimes stops unexpectedly. This has occurred at times while it is writing a file and, most recently, when receiving a reply from another WCF service. There are no exceptions being caught, as these all get logged, and there are no messages in the event logs on the server where both are hosted. I added logging to verify that the service is completing it's logic, which it is (taking about 6 minutes). All my timeouts are far higher than they need be. I'm starting to think the issue might be that the channel is getting closed and, due to the very high timeouts, an error is not yet thrown. Of potential relevance, the workflow is calling the wcf service asynchronously and then using a WaitOne() on the AsyncWaitHandle. I have a feeling this is maybe not the best idea, but I'm not sure if it could cause this issue. Also, persistence is not set up on the workflow (I had previously thought that the unloadOnIdle setting might have been causing issues with getting return values from the called service, as I'm not very clear on how this is supposed to work).
Any help/advice would be greatly appreciated.
Have you checked the timeout settings on the client. I know in the past I had to update both the client timeout settings as well as the server settings.
In the workflow App.config (missing a timeout for the hosting of the workflow?):
<bindings>

In the DalService WCF web.config:
<httpRuntime

executionTimeout="6000000"
/>
<basicHttpBinding>
<binding name ="LargeMessageBinding"
closeTimeout="00:01:00"

useDefaultWebProxy="true"
/>
<!--maxReceivedMessageSize="6553600" -->
<!--maxBufferSize="6553600" -->
Turns out, the workflow was not being hosted in its own worker process, as I had thought. Another app was crashing the process. The WCF service was correctly configured to use its own worker process, hence it would correctly return, but to a no longer running app.
I have a Console application hosting a WCF service:
Updated this code to run off the app.config file instead of initialising it programatically
Uri baseAddress = new Uri("http://localhost:8000/ChatServer/Service");
ServiceHost myHost = new ServiceHost(typeof(ClientServerChat.ChatServer), baseAddress);
myHost.AddServiceEndpoint(typeof(IChat), new WSHttpBinding(), "ChatService");
ServiceMetadataBehavior mb = new ServiceMetadataBehavior();
ServiceBehaviorAttribute attrib = (ServiceBehaviorAttribute)myHost.Description.Behaviors[0];
attrib.IncludeExceptionDetailInFaults = true;
mb.HttpGetEnabled = true;
myHost.Description.Behaviors.Add(mb);
myHost.Open();
The Console app compiles and runs. svcutil runs perfectly.
Svcutil runs against the new service code perfectly and generates the Client code and the ouput file
I'm calling svcutil via the Visual Studio Command Prompt like so: svcutil.exe http://localhost:8000/ChatServer/Service
It generates this output.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="WSHttpBinding_IChat" closeTimeout="00:01:00" openTimeout="00:01:00"

transactionFlow="false" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
allowCookies="false">

</bindings>
<client>
<endpoint address="http://localhost:8000/ChatServer/Service/ChatService"

contract="IChat" name="WSHttpBinding_IChat">
<identity>
<userPrincipalName value="Bedroom-PC\Roberto" />
</identity>
</endpoint>
</client>
</system.serviceModel>
</configuration>
Along with the bundled client code (which is in the same directory as the output file, I should add) I should be able to call the service with this:
ChatClient client = new ChatClient();
The new output from svcutil (both code and config) still throws this exception.
But it throws an exception saying:
"Could not find default endpoint element that references contract 'IChat' 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."
Interestingly, Visual Studio 2008 will crash when adding the same Service reference to a Client project.
VS2008 still crashes with the updated code.
It will find the service, get all the operations and what not. When I click Add, it crashes.
Any one have a clue whats going on??
Thanks in advance

Have you tried using the configuration file setup rather than doing it programmatically? Then at least you'll know if it's a general settings problem or something to do with your code. You could then roll out the code bits one by one; mex, then endpoint and see which kills it.
I fixed it.
I copy and pasted the system.serviceModel section from output.config into app.config after the the userSettings section and commented out the entire output.config.
I also specified the name of the endpoint when inistializing ChatClient("name").
It seems to be working.
Does VS2008 just die without any feedback? If so, check windows event log (app log) for error messages.
One plausible cause: VS2008 + System.Core.dll 3.5 + bad NGen images can cause crashes when VS2008 tries to load either System.Core or anything that references/depends on it.
You may also want to attach one VS instance to another (as debugger) to see any additional crash details. But I would explore the System.Core/NGen track first.
