Develop Reference

add service reference only works with localhost wcf service

I am trying to host a svc service in my web application and I am trying to connect to it with a simple client application.
When the host is hosted in my own computer and solution, and I run the web application locally, everything works fine, meaning that I can add the reference to the service using add service reference in my client solution with http://localhost:6543/Hello.svc as the address and when I navigate to the service's url, it shows me the service's information as it should.
But when I publish my website, and I try to add the reference to my service using add service reference with http://myserver.com/Hello.svc as the address, i get the error message bleow:
There was an error downloading
'http://myserver.com/Hello.svc/_vti_bin/ListData.svc/$metadata'. The
request failed with HTTP status 404: Not Found. Metadata contains a
reference that cannot be resolved: 'http://myserverc.com/Hello.svc'.
The remote server returned an unexpected response: (405) Method Not
Allowed. The remote server returned an error: (405) Method Not
Allowed. If the service is defined in the current solution, try
building the solution and adding the service reference again.
and oddly when I navigate to myserver.com/Hello.svc, the browser starts to download the Hello.svc file instead of showing the service's details and information.
this is my website's web.config file:
<system.serviceModel>
<bindings>
<webHttpBinding>
<binding name="crossDomain" crossDomainScriptAccessEnabled="true" />
</webHttpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="WithDebug">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
<services>
<service name="HelloWorldService.HelloService" behaviorConfiguration="WithDebug">
<host>
<baseAddresses>
<add baseAddress="http://myserver/Hello.svc"/>
</baseAddresses>
</host>
<endpoint
address=""
binding="webHttpBinding" bindingConfiguration="crossDomain"
contract="HelloWorldService.IHelloWorld" />
<endpoint
address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange" />
</service>
</services>
</system.serviceModel>
I think I am missing something big here, but since I am new to WCF, I don't know what it is.Any help would be appreciated and I am more than happy to issue more details about my project if needed.
Thanks in advance

You need to run ServiceModel registration tool
"This command-line tool provides the ability to manage the registration of WCF and WF components on a single machine. Under normal circumstances you should not need to use this tool as WCF and WF components are configured when installed. But if you are experiencing problems with service activation, you can try to register the components using this tool."

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
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="sslBehaviorConfiguration">
<!-- To avoid disclosing metadata information, set the values below to false before deployment -->
<serviceMetadata httpsGetEnabled="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<wsHttpBinding>
<binding name="sslBindingConfiguration">
<security mode="Transport" />
</binding>
</wsHttpBinding>
</bindings>
<services>
<service name="SslWCFProject.Service1" behaviorConfiguration="sslBehaviorConfiguration">
<endpoint binding="wsHttpBinding" bindingConfiguration="sslBindingConfiguration" contract="SslWCFProject.IService1" />

</service>
</services>
<!--<protocolMapping>
<add binding="wsHttpBinding" scheme="https"/>
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>-->

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.

Host WCF application without UAC/admin privilege

I have written a application which is hosting a WCF Service.
And I try to run the application with this config.
<?xml version="1.0"?>
<configuration>
<system.serviceModel>
<services>
<service name="MyApp.Service" behaviorConfiguration="ServiceBehavior">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8000/service"/>
</baseAddresses>
</host>
<endpoint address="" binding="wsHttpBinding" contract="MyApp.IService"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="False"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup></configuration>
But it cause the application need to run as administrator.
Is it possible to run this application without admin privilege? (If possible, change the config only.) In addition, I also need to add service references in Visual Studio to write a client program. If possible, please keep the application can be added service references in Visual Studio 2010.

If you want to keep it on an HTTP binding so a nonadmin can run it, you'll need to add permissions using the command
netsh http add urlacl (see help for the rest of the params)
This will allow the user you specify to carve off a chunk of the URL-space for the machine. If you don't want to do this, you'll need to change to a different binding (netTcp, for instance) that doesn't require special privileges to listen.

This solution worked for me (using HTTP binding), open your service on this URL:
http://localhost:80/Temporary_Listen_Addresses/
Must admit that i found it on this site http://www.paraesthesia.com/archive/2010/06/11/developing-as-a-non-admin-testing-wcf-services.aspx/ after google-ing for some time...So credits to that guy.

Based on the comment to my other answer, you won't be able to do this with the built-in HTTP bindings- they're all based on HTTP.sys, which requires rights to be granted to non-admin users to register URLs. If your deployment scenario allows, consider switching to netTcpBinding instead- no permission issues there. Otherwise, you're SOL with the built-in bindings- you'd need to build a raw HTTP transport that's not based on HTTP.sys.

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!
