I'm trying to learn WCF and I've created a new WCF Service Library project in VS2010. I haven't made any changes to the default project but when I run it the WCF Test Client displays an error. When I navigate to the metadata endpoint in a browser the result is a blank page.
What am I missing? I would have hoped that a brand new, untouched project would work correctly.
Here's the full error:
Error: An error occurred in the tool.Error: Configuration binding extension 'system.serviceModel/bindings/netTcpRelayBinding' could not be found. Verify that this binding extension is properly registered in system.serviceModel/extensions/bindingExtensions and that it is spelled correctly.
The service host seems to working properly.
Here's the config file. Just as it was "out-of-the-box"

This error is usually caused by a bad configuration in the "machine.config" file used by the .NET framework. Perhaps you installed the Windows Azure SDK and uninstall it, or the AppFabric SDK. In any case, you have entries in some sections that are causing these error.
Here the bindings from my machine.config found in C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config:
<bindingExtensions>
<add name="wsHttpContextBinding" type="System.ServiceModel.Configuration.WSHttpContextBindingCollectionElement, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
<add name="netTcpContextBinding" type="System.ServiceModel.Configuration.NetTcpContextBindingCollectionElement, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

See if you have other entries there and remove them.

I develop a wcf application ,so it works fine in local pc ,but when i publish it and i upload the published file i couldn't reference that service to my third application .

as you know in webconfig there is http://localhost:8733 and i change it to asp.spadsystem.com but no result.
So i added this reference to my application asp.spadsystem.com/WcfServiceLibrary1.Service1.svc ,but the visual third application can't find the service .
I am so new in wcf.
This is a WCF REST service. The service works perfectly fine on my dev machine.
I have the service files in a subfolder of wwwroot called Services\
Admittedly I'm well versed at writing code, but no so well versed at using IIS to host/publish we services.
What I attempted to do was just copy the Services folder from my dev laptop to the server's wwwroot folder.
When this happens and I try to access the service on the server I get some strange error that I don't understand (well I sort of understand it just don't know why it's happening)
"The type 'BooksService.Service1', provided as the Service attribute value in the ServiceHost directive, or profided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found."
Service1.cs looks like so in my project:
namespace BooksService
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in both code and config file together.
public class Service1 : IDataService
A decent portion of my web.config is based on google recommendations so it's probable I may not understand something or just have it plain wrong.
Web.Config looks like:
***<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
<!-- When deploying the service library project, the content of the config file must be added to the host's

My service file looks like this:
<% #ServiceHost Service="BooksService.Service1" %>
Then there is a bin folder which contains my .dll
So the folder layout is as follows:
c:\inetpub\wwwroot\SERVICES\BookService\bin
Where service.svc is in the BookService folder and the assembly is in the bin folder.
What step(s) might I be missing?
First, you need to create an application in IIS and point the virtual directory to your application folder: c:\inetpub\wwwroot\SERVICES\BookService.
Then you need to update your service base address accordingly:
<baseAddresses>
<add baseAddress="http://localhost/services/bookservice" />
</baseAddresses>
You can test the url by typing it in your browser and browsing to the service location.

I created WCF Project host service on my machine from this tutorial:
http://www.aspdotnet-suresh.com/2011/06/introduction-to-wcf-wcf-tutorial-wcf.html
After my WCF service run on my machine i cannot connect with my client to my service and received EndPointNotFoundException (this happen from local and from remote machines) and this is not the case if my service running through visual studio.
what could cause this error ?

You should run Service under administrator privileges. Windows services already have that's why you can run it without problem.
I have created a WCF service and hosted it in a windows service. Testing this service with visual studio works fine and I can consume it. Now I have installed the service on a PC (called PC1) and using another PC (called PC2) I wish to be able to discover it and consume it. I imagine that I will have to modify the app.config file to achieve this.
Here is my current app.config, what do I need to modify to get this to work from other networked computers? I'm guessing the base address is a start?

oh and i'm running .Net 4.5
(if the web service is not implemented, I recommend this link
http://www.codeproject.com/Articles/28693/Deploying-ASP-NET-Websites-on-IIS-7-0)
You should try to modify the web.config in this place:
<baseAddresses>
<add baseAddress="http://192.168.1.2/Design_Time_Addresses/WcfAVOLibrary/AVOs/" />
</baseAddresses>
where 192.168.1.2 is your current ip, or localhost works too, it would see like this:
<baseAddresses>
<add baseAddress="http://localhost/Design_Time_Addresses/WcfAVOLibrary/AVOs/" />
</baseAddresses>
At first place, change localhost by pc1 on base address, like
http://pc1:8733/Design_Time_Addresses/WcfAVOLibrary/AVOs/
After it, try to open the base address url from browser on pc2 (yes, never mind that it is win. service - this is your service url and should be accessible). It should be ok, you need not to continue before you get it work.
When it done - review client's config to match service address.
Was facing the same issue. Added inbound rule to open the port 8733 in Windows Firewall. It worked!
One of my methods returns byte[], of a file. All other methods return either string objects or custom objects
I can view the WSDL via a browser and as i have used WCfExtras, I can even view the documentation.
In my test app, C# web application, I add the reference to my svc, hosted on a test server. I get an error as such:
The document was understood, but it could not be processed.
- The WSDL document contains links that could not be resolved.
- There was an error downloading ...
- Unable to connect to remote server
- No connection could be made because the target machine actively refused it
Content Type application/soap+xml; charset=utf-8 was not supported by service . The client and service bindings may be mismatched.
The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'..
If the service is defined in the current solution, try building the solution and adding the service reference again.
This is my app.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionStrings>
<add name="TestApp.Properties.Settings.TestDBConnectionString"
connectionString="Data Source=192.168.2.130;Initial Catalog=TestDB;Persist Security Info=True;User ID=sa;Password=xerox"

Any ideas on how I would resolve this? Should I have 2 different bindings, one for methods returning non bytes[] and Mtom for method returning byte[]? If so how does one apply bindings per method exposed?
Tried running it with WcfTestClient.exe and this is the error

Verify that you passed all the metadata documents to the tool.Warning: If you would like to generate data contracts from schemas make sure to use the /dataContractOnly option.
I have the same problem. I was hosting the wcf on remote win2008 server on IIS. The solution that has worked for me was setting the host name when adding web site and don't leave it blank after setting all other data for hosting!
On the client app, do you have a reference to the WCFExtras assembly? The error appears to be saying that the binding is not recognized, which is, I assume, because of the extensions introduced by WCFExtras. Try adding the same extensions section to your client's config file as is in the server's config file.
Your binding is basicHttpBinding, but your binding configuration is wsHttpMTOMBinding.
This looks like a mismatch, however it could be just the names that you have given things.
Try opening the config file in the WCF config tool, this should tell you (refuse to open the file), if there are inconsistencies in your config file.
Hope this helps
Shiraz
This can't be a true answer, but after I removed WCfExtras references from my app.config file and deployed, things seem to work.
This is what I was trying to achieve, but have abandoned for time being
WCF Extras
If anyone has an idea of how and what I configured wrong, please advise on this column.
Many Thanks
The answer for me to be able to use the WCF Test Client is to set the set singleFile="true" in the web config like this.
<behavior name="Sample.WsdlSampleEndpointBehavior">
<wsdlExtensions location="http://localhost:8731/TestApp/Service1/" singleFile="true" />
</behavior>
