I'm working from a project on localhost:2971 and in the master page i want to include an asp:ScriptReference to a wcf service i am hosting in IIS at localhost:5152
<Services>
<asp:ServiceReference InlineScript="false" Path="http://localhost:5152/CostService.svc" />
</Services>
then i attempt to call:
var service = new SandwichServices.CostService();
service.CostOfSandwiches(5, onSuccess);
on a page that inherits from the master page.
however, in the firefox error console i get the following:
Error: no element found
Source File: http://localhost:2971/CostService.svc/CostOfSandwiches
Line: 1
So why is the source file pointing to 2971?
the service works fine on the sample page i created on 2152.
Anyone know whats up?
Any help would be much appreciated!

I would think you are developing using Cassini (Web Server Inside VS). You need two instances of Cassini to have access to the 2 ports you are talking about. If it was IIS the portnumber is not required.

That first error basically means that you have tried publishing multiple different protocols in the same App Pool. You need to have separate IIS App pools for the different protocols.
Also make sure that the Application Pool is running with the Isolated Host user.
I have a project with several WCF services (mix of REST and SOAP). The project has been running On-Prem for 6 months without an issue. We are moving this to Azure but have run into an issue that will prevent us from going live.
The project uses Autofac for it's IOC. We are gonig to host this in a Cloud Service in Azure. Everything appears to work correctly when running locally in the Azure Emulator however once we deploy using the Cloud Service project, everything builds and deploys correctly, but we receive the following error when trying to access a service.

It appears that it's having an issue with the service configuration endpoint. That is registered through Autofac WCF integration using the OOTB RouteTable here:

All of this works fine in IIS and the local Azure emulator, but once deployed to the cloud service is where we get an issue.
Observed exactly problem. Solved by canceling IntelliTrace on this hosted service.
I did publishing from VS2013 and marked "Enable IntelliTrace" during publishing. Once I canceled this option and re-publish - all works properly....
Answer
It was a configuration problem.
We had two services in the application. Prior to the problem, both services had explicit binding configuration that matched and worked well. One service was going to be removed, so the dev remmed out the explicit binding configuration, forgetting that .NET 4.0 provides default (and different) bindings.
Whichever service was hit first, its settings would not be incompatible with any other settings (since it was first) and would be fine. The service that was loaded subsequently would have different binding settings and be refused by the TransportManager.
The apparent intermittency was due to us only focusing on the one remaining service, thinking the other service was no longer in the picture. A monitoring utility was still hitting the removed service and would get in sometimes before we could reload the other service after a configuration change.
Original Question
We're getting an intermittent error when first starting up a service in IIS. If I make a whitespace change to any of the configs and reload, then about 50% of the time the service will come up fine. Once it's up, it's good to go. But the next time we deploy to this box, we start the russian roulette all over again.
We've looked over other forum posts on the same error and so far have not been able to come up with a definite fix. It took us a while to realize that none of the configuration changes we were trying were actually influencing the problem since merely a whitespace change is enough to get it to start afresh and get it to work part of the time. Seems there's some sort of race condition internally with the TransportManagerTable, perhaps it's empty when the service fails to come up? Not sure, trying to get some tracing or something to give us better info on what's in the TransportManagerTable instance.
There is no compatible TransportManager found for URI 'net.tcp://box:10101/DEV/AwesomeService.svc'. This may be because that you have used an absolute address which points outside of the virtual application, or the binding settings of the endpoint do not match those that have been set by other services or endpoints. Note that all bindings for the same protocol should have same settings in the same application.

Edited the configuration to set the Address Empty and the error was fixed.
To add a little bit more instruction, the issue is most likely in the Web.Config file of your service. In the node, make sure that your Endpoint Address is an empty string -or- make sure that your Endpoint Address URL points to the exact location of your service, as you specified in IIS.
<endpoint address="" binding="basicHttpBinding" bindingConfiguration="MyServiceBinding" contract="MySolution.IMyService"/>
I will go through what i've done so far step by step as below:
created empty solution
added a website WCFService
deleted the Service and IService from the website
added a WCF service library project to the solution
added end points to the web.config
did the same in app.config
added a reference to the service library in the web application

this is really driving me crazy!!!
why am i getting this error?
if you need more information please let me know so that i provide them to you
thanks a million in advance
Look at the WF_Ledger.svc file in your web site project. It should only consist of one line. There'll be Service attribute containing "Services.WFAPILedger.WF_API_Ledger". WCF is looking for the "Services.WFAPILedger.WF_API_Ledger" class but not finding it. The namespace and class name need to either exist in the web site project or be a reference as you're trying to set up. You'll need to edit that Service attribute to match the service implementation class in the WCF service library project.
Please check if the .svc file is provided and is of the following form.
<% #ServiceHost Language=C# Debug="true" Service="MyService" CodeBehind="~/App_Code/Service.cs" %>
Its all one line and the file should contain nothing else.
Try to add new default service then check newly added works fine.
If yes, check web.config endpoint contract name provided,
and in .svc file check code behind mentioned correctly.
In .svc file Service parameter should include namespace followed by class name i.e. it should be in the format mynamespace.myservice
Build the WCF project and try again. This error may occur because of the absence of a DLL in bin folder.
For me building and trying again resolved it.
Even make sure that, In your .svc file directive, The "service" attribute's value is fully qualified class name, i.e example: if your namespace is like "ns1.ns2.ns3.ClassName" (where ns1, ns2,ns3 are namespaces).
This error can be generated by renaming a class name in the *.svc.cs file without renaming it in the *.svc markup.
Two ways to resolve this problem:
Rename the class name to the original name.
Rename the service reference in the markup (right click in *.svc file, then click "View Markup"*).
Your markup code looks like this:
<%# ServiceHost Language="C#" Debug="true" Service="WCFSample.MyClass"CodeBehind="MyClass.svc.cs" %>
*Note: I had this problem in VS2017, don't know if that option is in VS2010.
check the function name and parameter in Iservice class where you calling the function and checkout your Service class also where function is define..
I am running on Windows 7/IIS 7.5, and have a web service set up to use net.msmq, but when I attempt to access the service using HTTP, I get the following error:
The protocol 'net.msmq' does not have an implementation of HostedTransportConfiguration type registered.

I have set both http and net.msmq bindings on the site under which it resides, and have enabled both protocols ("http,net.msmq") on both the site and application.
I've looked at the article Debugging a Missing HostedTransportConfiguration Type and have run all the commands there, but none seemed to help; running sc query netmsmqactivator shows:
SERVICE_NAME: netmsmqactivator
TYPE : 20 WIN32_SHARE_PROCESS
STATE : 4 RUNNING

WIN32_EXIT_CODE : 0 (0x0)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x0
WAIT_HINT : 0x0
The App Pool that the application is running under right now is targeting .NET Framework v2.0, but if I change the app pool to target .NET Framework v4.0 (and make appropriate changes to the service's web.config to remove duplicate configSection definitions), I am able to see the WSDL just fine.
As far as I know, the web service is not meant to be run targeting .NET Framework v4.0; it is actually working for a colleague of mine (also running Windows 7), but comparing setups isn't viable at this time for numerous reasons.
Another note, may or may not be related:
After attempting to access the service via HTTP and getting the above error, refreshing the service results in:
An item with the same key has already been added.
[ArgumentException: An item with the same key has already been added.]

This requires an app pool recycle to clear.
I don't have experience working with net.msmq, so I do not know what pertinent information I may have left out; please let me know what I've missed.
Figured it out: Not sure what was messed up, but turns out that uninstalling then reinstalling WCF Non-HTTP Activation fixed it.
If you are hosting an MSMQ/WCF service in IIS, you have to tell IIS to allow net.msmq protocol. It's in the advanced settings for the application or site in which you are hosting the service.
