WCF Service Unable to start debugging on the web server

I am having an issue debugging my WCF service when I set the WCF service to SSL Required in my local IIS. I am able to hit the URL correctly for my service under http/https but I cannot debug and step through the code. I received a popup box with the following text:
Unable to start debugging on the web server. The web server is not configured correctly.
When I make the service not SSL Required I am able to step through my code as expected. I am new to dealing with IIS and have gone through a number of tutorials with the same result. Any help would be awesome

1) First, I recommend checking the IIS logs. They are usually located in the following directory: C:\inetpub\logs\LogFiles. Just go into the W3SVC prefixed folder whose modification date most closely matches when you received the error. Open the log for the correct day and see the error details.
2) If that reveals nothing, then check out the Windows Application log in your Event Viewer.
3) Do you have a certificate (e.g. self signing certificate) on your computer? Is there a trusted site issue here?

I believe I found my answer. It looks like the checkbox in IIS for the website for Require SSL is associated the client certificate and requiring a client certificate to access the service instead of the section which is below it (although I will need to select required in the future). For the post I found When this is checked off I cannot debug the service but I can attach to the process in order to debug it.

If I am wrong please let me know. If I come across anything else I'll update this question again with my progress just to keep in documented.

Hosting WCF Service on IIS

I am new to WCF and windows mobile development. I am trying to create an occasionally connected application that utilizes the MSFT sync framework and this requires the use of a WCF service.
I have a visual studio project containing my smart device project, a WCF Service Library project, and a WCF Service website project.
The service is hosted fine on my local machine not using IIS and I can access it at http://localhost:55149/ElectricReadingServiceSite/ElectricReading.svc
However when I add it to IIS it gives me an http 404 resource cannot be found error. I cannot figure out why it thinks the resource is not there.
Here is my web.config:
<?xml version="1.0"?>
<configuration>
<system.serviceModel>
<services>
<service name="MiddleTierServiceLibrary.ElectricReadingCacheSyncService"
behaviorConfiguration="MiddleTierServiceLibrary.ElectricReadingCacheSyncServiceBehavior">
<endpoint
address=""
binding="basicHttpBinding"
contract="MiddleTierServiceLibrary.IElectricReadingCacheSyncContract">
<identity>
<dns value="10.104.238.123"/>
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="MiddleTierServiceLibrary.ElectricReadingCacheSyncServiceBehavior">
<serviceMetadata httpGetEnabled="True"/>
<serviceDebug includeExceptionDetailInFaults="False" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
My ElectricReading.svc looks like this:
<%# ServiceHost Language="C#" Debug="true"
Service="MiddleTierServiceLibrary.ElectricReadingCacheSyncService" %>
Any help is greatly appreciated!
EDIT: Are there any tools or steps I can take to get a better idea of what is going wrong? The 404 error does very little to help me.

There can be a number of reasons to why this could be happening.
Some of them might include:
Make sure you uploaded the assembly in the Bin folder
You have set up a website on IIS, but you are not accessing it with
the correct address(make sure the port is correct)
Your application pool is not set up for the website(if you are using
.NET 4.0 you need to set the applictation pool to version 4.0) In IIS manager go to ApplicationPools and set the pool to the version of .NET that you are using
Try using Fiddler. It should log the calls it makes and thus give you a little more detail on what it is not finding.

WCf REST service client side config file empty

I have a REST service and I have added it's reference in my WPF application. But as soon as I create a client of my proxy, it throws error and it throws error because my client side app.config is empty:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
</configuration>
This line on client throws error:
HelloWorldClient client = new HelloWorldClient();
This is my system.servicemodel section of web.config on the server side:
<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
<services>
<service name="WCFRestExample.HelloWorld">
<endpoint address="" binding="webHttpBinding" contract="WCFRestExample.IHelloWorld"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true" />
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
Can anybody tell me why is app.config empty? I have also restarted VS2010 but no luck.
NOTE: When I directly browse it in the browser the service is working. So, there is no problem with server side service.
Thanks in advance :)

As some other posts mentioned (such as After creating a wcf service how do I tell whether its restful or soap from the wsdl? and Create a WCF Proxy for a Rest Web Service, among others), Add Service Reference does not work for REST endpoints. You'll need to create the client yourself.
Another issue in your web.config: in order to create a REST endpoint, you need both to have the webHttpBinding (which you do) and add a <webHttp/> endpoint behavior to your endpoint (which you don't).

WCF - Service Reference not be created

My WCF service was working correctly and then all of sudden it stop working. I don't think I changed anything with the configuration.
The WCF service is hosted by a windows service.
What is weird is when I add the service reference, it will identify the contract and all the methods exposed. But if I go to a browser I get a 404 error and the compiler is not creating the service. I have deleted and tried to re-add the reference with no luck
Also, my deployed application is still able to access the wcf service.
Question 1:
In a WCF windows service, should I be able to see the wsdl inside a browser (http://localhost:8080/MaestroService/mex). In IE, I am getting 400 Bad Request. I am assuming that this is the root of the problem.
Question 2:
Is there something else?

Custom tool warning: Cannot import wsdl:binding
Detail: There was an error importing a wsdl:portType that the wsdl:binding is dependent on.

Update
I turned on the tracing and I saw this:
The message with To 'http://localhost:8080/MaestroService/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. I will update this question if I figure it out.
Update V2
I went to another project inside the same solution. I was able to add the service there with no problems. I notice I was using 3.5 in the console app vs 4.0 in the wpf browser app. When I came back to report this, I noticed in my last update that it had /mex/mex even though I put http://localhost:8080/MaestroService/mex in the url . I tried just http://localhost:8080/MaestroService and it work!!!
In the end, I did end up using Migual Castro technique here, where you create the conracts and the proxy. Which was good to see how it really works and what VS is doing. But it would be good to have that day and a half back.
thanks for the suggestions everyone.

You are running as a windows service.
A windows service runs in the security context of a user account.
If the password of the user account changes or expires, the service does not run.
The first thing that you should check is: Is the service running.

Unable to properly reference a wcf dataservice

I'm having a couple of issues which may be related, or may not. I noticed that when I use Add Service Reference in Visual Studio to add a reference to my data service, the reference.cs it generates does not compile. It complains about a missing namespace. I can fix it up to compile, but this happens every time I update the reference, and it's worrying on other levels too, such as "will this cause other issues".
I also noticed that when I do this, my host server (a console application hosting the data service) logs this:
An exception occurred [System.Data.Services.DataServiceException] :: The URL
representing the root of the service only supports GET requests.
This is the service config:
<service behaviorConfiguration="behaviour" name="StatsPlus.Server.HostedServices.SPDataServiceHost">
<endpoint address="svc" binding="webHttpBinding" contract="System.Data.Services.IRequestHandler" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:8752/DataService/"/>
</baseAddresses>
</host>
</service>
And the behaviour:
<behavior name="behaviour">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
<dataContractSerializer maxItemsInObjectGraph="10"/>
</behavior>
When I try to run svcutil http://localhost:8752/DataService/, I get this:
HTTP GET Error
URI: http://localhost:8752/DataService
There was an error downloading 'http://localhost:8752/DataService'.
The request failed with HTTP status 405: Method Not Allowed.
Any ideas? Much appreciated
Thanks

I think you're connecting to a wrong address. You have a base address
<add baseAddress="http://localhost:8752/DataService/"/>
and on top of that a relative endpoint address
<endpoint address="svc" binding="webHttpBinding"
so your complete URL will be the combination of the two:
http://localhost:8752/DataService/svc
Did you try to connect there??
I am not sure if you can have a "mex" metadata exchange endpoint with WCF REST services, really. I was under the impression that the client-side proxy for a WCF Data Service gets its metadata over a special URL call from the HTTP endpoint. So maybe try to remove that from your config as well (and you can't use svcutil on that service, I believe - svcutil is only for SOAP service calls, if I'm not mistaken).
Also, since you're using webHttpBinding and self-hosting, you need to add the webHttp behavior:
<behavior name="behaviour">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
<dataContractSerializer maxItemsInObjectGraph="10"/>
<webHttp />
</behavior>
If you do these two steps, I think you should be able to get at your WCF Data Service. Try it and let us know!
