I am trying to enable an additional net.tcp endpoint (which uses Username authentication) for an existing WCF service. The service is hosted in IIS7.
Executing a client against the service returns an error that the socket connection was aborted. Enabling tracing against the service reveals the following exception is thrown:
System.ArgumentOutOfRangeException
The value of this argument must be positive.
Parameter name: maxAccepts
Actual value was 0.
I'm confused, because as best I can tell port sharing should be disabled by the configuration (see below), but it's still calling through the port sharing code (again, as best I can tell). In any case, I can't find any way to specify this maxAccepts value; Google doesn't know anything about it, and the maxPendingAccepts value doesn't seem to do it. How do I resolve the error?
The service's config file contains the following for the net.tcp endpoint:
<bindings>
<customBinding>
<binding name="netTcp">
<security authenticationMode="UserNameOverTransport" />
<windowsStreamSecurity />
<tcpTransport portSharingEnabled="false" listenBacklog="10" maxPendingAccepts="10" maxPendingConnections="10" />
</binding>
</customBinding>
</bindings>

Edit: I have installed the non-HTTP WCF activation components, run ServiceModelReg.exe, added net.tcp and net.pipe to the list of enabled protocols in IIS Manager, etc. No joy.
I've also written a quick Windows Service to host the service (not the ideal long-term solution for us), and the Net TCP connection works fine there, so it doesn't appear to be anything in my configuration or code, which means something isn't right in/with IIS. Does the app pool for the application have to be running in Integrated mode? I tried it both ways, it didn't seem to make a difference, but our app currently is installed in Classic mode.
As best I can determine, the problem is simply that .NET does not like hosting two services in the same IIS application when one is a Soap11 endpoint and one is a NetTcp endpoint. Removing the Soap11 endpoint allows the NetTcp endpoint to work without error.
We've moved to a model where we are using a Windows Service to host the NetTcp endpoint and left the Soap11 endpoint in IIS.
If anyone figures out how to host both a NetTcp and Soap11 service in the same application in IIS, I'd love to hear about it.
Net.tcp does not work on IIS7 out-of-the-box, there are a number of things that need to be activated.

I made a WCF Rest Service and attached it to IIS 7 on my server and it worked great. Suddenly, we had a hard drive failure and the guys who're supposed to manage the backups didn't back up anything, so we lost all our stuff on the server.
So I go about setting everything back up, and I put all the stuff on IIS. We have another WCF Rest Service that does a lot of stuff the one I made does, including a couple of the same methods for authentication and such. But now it seems that mine won't work. Our website works and our other web service works, but not this one, and I've no idea why? I set them up the exact same and I don't think I changed anything when I did it initially.
The help reference pages work, but when calling the method, I get
"The server encountered an error processing the request. Please see the service help page for constructing valid requests to the service."
I'm using the same methods as before, calling them with the same arguments, this happens for every method, regardless of GET or POST. I've used a REST extension thing in chrome to call it and the mobile app that I usually use to call it, as well as the browser and they all come up with the same error.
Here's the web.config file for it (I've tried adding a few things found on stackoverflow to get to the problem, but it's not done anything, really).

Looking at the stack trace from your log, I think you are having issues parsing a GUID in MobileAssessorAPIService.GetProjectData method
at System.Guid.TryParseGuidWithNoStyle(String guidString, GuidResult& result)
at System.Guid.TryParseGuid(String g, GuidStyles flags, GuidResult& result)
at System.Guid..ctor(String g)
at OHS.MobileAssessor.Services.MobileAssessorAPIService.GetProjectData(String token)
I would recommend that you put a break point in this method and attach a debugger to your REST service.
Based on the code you posted, the suspected line is
MobileAssessorAuthenticationResults authResult = ValidateToken(new Guid(token));
if you are not able to remotely debug this, I would recommend that you add logging just before this line to log the value of token. something like
logger.Log("paramater token = " + token);
Alternately, use wireshark to check the value of the token. once you extract the value of that guid, validate it online at http://guid.us/Test/GUID
When I try to call a WCF service I developed I get this error message: "Method or operation is not implemented".
Let me explain the scenario I'm facing and them I'll give you more details, the code and etc:
I'm developing a WCf service in .NET framework 4.0 in a Windows 8/Visual Studio 2012 machine.
The WCF service will be accessed from a mobile application developed in .NET compact framework 2.0 (Dev environment: a Virtual Machine running Windows XP service pack 3, Visual Studio 2008, Windows Mobile 6.1 Professional Emulator).
The WCF service is using the SAP .NET Conector (SAPnCO) version 3.0.
When I run the service using VS integrated IIS or IIS8, everything goes fine: I can test the service, access it from a test console application and can access it from Windows Mobile Emulator.
However, we where about to start some preliminar tests with the final users and we still didn`t have a proper server to deploy the WCF application, so I had to make a contingency server using Windows XP and IIS express 7.5 (I was not able to make it work on IIS 5.1).
I know that IIS Express is for local access only, but I followed this tutorial to open ti to the LAN: TUTORIAL.
Doing so I can acess the service signature via browser and see the WSDL file.
Everytime i try to acess the service I get the error message "Method or operation is not implemented". I`ve been looking for some similar problem over the internet for the past 4 hours without success.
Here`s what I managed to do so far:
Host a default WCF sample service on IIS Express 7.5 and use the service remotely: ok;
Reduce the scope of the original service to the minimal only: still get the same error;
So, I still don't know what can be causing this or how to solve it. I kindly request for your help, please!

Since the WEB.CONFIG file is the only piece of the service that is edited to make the WCF service work with IIS Express I think this can (evetually) be the source of trouble. I`m posting the original WEB.CONFIG file, without the edits hoping that this can help someone spot the problem!

I have found, this exception occurs if sapnco assembly is not loaded. Try to set referenced SAP assemblies to Copy local: True.
It is not ideal solution, but it has worked for me well.
I resolved it by moving the configSections' section to the top of the app.config. Maybe the 'configSections' must be the first child section of configuration.
See here too:
Parameter 'sectionGroupName' is invalid
I have a self hosted .Net 4.0 WCF service that I'm trying to convert from WsHttpBinding to NetTcpBinding for performance reasons. The service works just fine with the WsHttpBinding.
Strangely enough, The service seems to work after switching to NetTcpBinding. (The service posts messages to a enterprise messaging system, and the message is posted and the client receives no error) however the following error is written to the server log:
Error: Service: MessageSenderService, Details: System.ServiceModel.CommunicationException: The socket connection was aborted. This could be caused
by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue.
Local socket timeout was '10675199.02:48:05.4775807'. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

Again, no error occurs on the server log when using the WsHttpBinding.

We build the client binding in code, not config. That looks like this:
return new NetTcpBinding(SecurityMode.None, reliableSessionEnabled)
{
MaxBufferPoolSize = Int32.MaxValue,
MaxReceivedMessageSize = Int32.MaxValue,
ReaderQuotas = new XmlDictionaryReaderQuotas
{
MaxArrayLength = Int32.MaxValue,
MaxDepth = Int32.MaxValue,
MaxStringContentLength = Int32.MaxValue
},
ReceiveTimeout = TimeSpan.FromMinutes(1.0),
CloseTimeout = TimeSpan.FromMinutes(1.0),
OpenTimeout = TimeSpan.FromMinutes(1.0),
SendTimeout = TimeSpan.FromMinutes(1.0)
};
Any ideas out there?
EDIT: I would like to add that I see the error on every call to the service, not only under load. The request and response messages are very small so it likely not related to message size. The error is written almost instantaneously, so it it not a timeout problem.
Fixed it.
As it turns out, I was not properly closing the client proxy. For whatever reason that didn't cause a problem with the WsHttpBinding, but with NetTcpBinding it caused that error.
After putting the client proxy in a using block the problem went away.

changing the buffer length, etc... Didn't solve the issue. The database is the sample NorthWind database
I am able to browse to the service
It seems that Aliostad is correct as I recreated the service without using IIs and used ASP to consume the service, and get the below error. So it is a problem invoking the svc from the app, I can still run the service directly via http

I found an article that says that with entity framework 4 there is a problem to serialize entities in wcf with lazy loading enabled
I added the following code to the service and everything works
context.ContextOptions.LazyLoadingEnabled = false;
link to article http://geekswithblogs.net/danemorgridge/archive/2010/05/04/entity-framework-4-wcf-amp-lazy-loading-tip.aspx
How many records are being returned? There are a couple of things in play here:
From a WCF Perspective:
MaxBufferSize: Gets or sets the maximum size of the buffer to use. For buffered messages this value is the same as MaxReceivedMessageSize. For streamed messages, this value is the maximum size of the SOAP headers, which must be read in buffered mode. For a non-streamed message, if the message size is greater than this property, then the message is dropped.
If not specified, this defaults to 65536.
This is only 0.0625 megabytes!
MaxReceivedMessageSize: Gets and sets the maximum allowable message size that can be received.
Default here is also 65536 bytes.
MaxStringContentLength: Gets and sets the maximum string length returned by the reader.
Your service is probably returning a value greater in size than the defaults.
So, you could try modifying your service behavior to include these attributes with higher limits, say 6 MB or so to see if it resolves your issue.
Also - remember there is maxRequestLength limit which is enforced by IIS which trumps any WCF setting, the default is 4096 KB, so you may have to tweak that if you alter the above properties.
Whew! Ok… I solved my Wcf / Linq errors (and learned a lot – a series of blog posts will follow next weak). Now I need to deploy. We run on the Mosso / Rackspace cloud, and for the moment that environment runs in a partial trust environment.
To make it simple, I added a method to my Wcf service that does just about NOTHING.
public string Echo(string what)
{
return what;
}
I built it all, and shipped it to the test server with the following Web.Config (relevant section only)… yes, I will need to add security obviously before exposing the dangerous methods, but for now I jsut want the anonymous stuff running :)
<system.serviceModel>
<bindings>
<basicHttpBinding>

<security mode="None"/>

<serviceHostingEnvironment aspNetCompatibilityEnabled="true">

<add prefix="http://backend.FooBar.com"/>
</baseAddressPrefixFilters>

</system.serviceModel>
So, off I go to call it in the simplest way I can with a console application. i add the service reference and it adds fine. Then I call it (I took inactive code for brevity)…
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using CoreWcfHarness.CoreDataServiceReference;
namespace CoreWcfHarness
{
class Program
{
static void Main(string[] args)
{
var context = new CoreDataWcfServiceClient();
var echoval = context.Echo("Hello World!");
Console.WriteLine(String.Format("{0}\n", echoval));
Console.ReadKey();
}
}
}
And blammo. I get hit with an exception.

"Request Failed" could be a number of things.
It looks like the most probable reason is that the request is not reaching the server. You should check the server logs to make sure that the request is being sent to the correct place.
