I have another simple aspx page created to test whether service is accessible or not. But when I am trying to run this service error displayed is Failed to add a service. Service metadata may not be accessible. Make sure your service is running and exposing metadata. Can anyone tell me how to resolve this error.
Thanks in advance.
My web service and contract is as below
namespace WcfService1
{
[AspNetCompatibilityRequirements(RequirementsMode =
AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1 : IService1
{
public string GetData(int value)
{
return string.Format("You entered: {0}", value);
}
}
}
Contract looks like below
namespace WcfService1
{
[ServiceContract]
public interface IService1
{
[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped,
ResponseFormat = WebMessageFormat.Json)]
string GetData(int value);
}
}

You need a mex service endpoint to allow metadata to be exposed. Add a new endpoint under service node like:
<endpoint address="mex" binding="mexHttpBinding" name="MetadataEndpoint"
contract="IMetadataExchange" />

Using Net.TCP WCF in IIS

I am trying to setup a NetTCP WCF service.
This is my server code:
iSync.cs:
[ServiceContract]
public interface ISync
{
[OperationContract(IsOneWay = true)]
void UploadMotionDynamic(byte[] jpegStream, string alias, Int16 camIndex, byte[] motionLog, double mul, byte isLive, byte doIsave);
}
Sync.cs:
public class Sync : ISync
{
public void UploadMotionDynamic(byte[] jpegData, string alias, Int16 camIndex, byte[] motionLog,double mul,byte isLive, byte doIsave)
{
//do stuff
}
}
web.config:
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="NetTCPBehaviour">
<serviceDebug includeExceptionDetailInFaults="True" />
<dataContractSerializer maxItemsInObjectGraph="65536" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service name="Sync" behaviorConfiguration="NetTCPBehaviour">
<endpoint address="net.tcp://localhost:8888/Sync" binding="netTcpBinding" contract="ISync" name="wsSyncerMotion" bindingConfiguration="NetTCPBindingEndPoint"/>
</service>
</services>
<bindings>
<netTcpBinding>
<binding name="NetTCPBindingEndPoint" sendTimeout="00:01:00">
<security mode="None" />
</binding>
</netTcpBinding>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
Now it cannot be the port being blocked because I even tested it by turning off the firewall.
I have made sure 'Net Tcp Listener Adaptor' is running in my
services.
I have added net.tcp in my IIS\Advanced Settings| Enabled
Protocols.
I have added the Non-HTTP activation setting in .NET
Features.
I have followed the links kindly supplied by people here.
The error I get (now) is:

My RESTUL WCF doesn't work properly

When I enter the url
localhost2/MySite_WebSite/Pages/Client/Competitions.svc/DoWork
, it doesn't work.
I have a breakpoint at the begining of the method, and I can see the method gets called twice, yet it doesn't return anything (I don't even think it send any HTTP code backs).
What did I do wrong?
Additional notes:
Entry is actually a "base class".
public class EntryCompetition : Entry
public class EntryEvent : Entry
In my code the dictionary actually contains EntryCompetition and EntryEvent instances.

Thanks for posting your code that definitely helps. But i think you're going to need to show a little more work, and some more concrete results on how your project is failing. But so as not to leave you helpless. I recommend looking at Fiddler
http://www.telerik.com/fiddler
It allows you to create Http requests and to see the responses inside of it's console. it is useful for seeing specifically what http response code your endpoint is returning, and allows you to modify your request through the composer window.
another helpful tip, would be to step all the way through your code, so you can point us to exactly what line is failing or what values are being set before your method completes.
Without more information, my best guess is you're code is throwing and most likely swallowing an exception. Or your methods or calls are setting null values that don't return the values you expect. Please reply once you've setup some further tests and updated your question if you are still having issues.

Ok, I solved the problem. I use a custom piece o code to serialize the dictionnary into a JSON string and I don't use DateTime objects as keys anymore.

Instantiating WCF Service Weird Error

I am trying to add a reference to a WCF service from my C# Desktop app.
I can add the service reference OK but as soon as I try to open the form within this desktop app I get this error:
NB. I have a UserControl that instantiates a reference to my WCF service and the control in in my GUI Form Class.
Could not find default endpoint element that references contract '' in
the ServiceModel client configuration section. This might be because
no configuration file was found for your application, or because no
endpoint element matching this contract could be found in the client
element.
This is in my app.config file:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IMotionUpdater" messageEncoding="Mtom" />
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://a url/MotionUpdater.svc/MotionUpdater.svc"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IMotionUpdater"
contract="wsCloudFeeder.IMotionUpdater" name="BasicHttpBinding_IMotionUpdater" />
</client>
</system.serviceModel>
</configuration>
And this is in my web.config file:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="basicHttpBindingEndPoint" maxReceivedMessageSize="10485760" messageEncoding="Mtom" closeTimeout="00:00:10" openTimeout="00:00:10" >
<readerQuotas maxArrayLength="32768"/>
</binding>
</basicHttpBinding>
</bindings>
<services>
<service name="MotionUpdater" behaviorConfiguration="ThrottledBehavior">
<endpoint address="MotionUpdater.svc" binding="basicHttpBinding" bindingConfiguration="basicHttpBindingEndPoint" contract="IMotionUpdater"></endpoint>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ThrottledBehavior">
<serviceTimeouts transactionTimeout="1"/>
<serviceThrottling maxConcurrentCalls="64" maxConcurrentInstances="1" maxConcurrentSessions="50"
></serviceThrottling>/>
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
If I invoke this reference from a browser window it displays all OK.
It is only where I have a variable in my form class I get the error:
UserControl.Class:
private static wsCloudFeeder.MotionUpdaterClient wsFeeder = new wsCloudFeeder.MotionUpdaterClient();
Server Class:
[ServiceContract]
public interface IMotionUpdater
{
[OperationContract]
void UploadMotion(byte[] jpegStream, string alias, Int16 camIndex);
}
The extra weird thing is that when I run my application it all works no problem.
Also, I have tried just doing this in my control Class but still cannot open up my GUI form..
private static wsCloudFeeder.MotionUpdaterClient wsFeeder = null;
Thanks...

Web.config for simple WCF Web Service

I have created the simple web service.
Code:
[ServiceContract]
public interface ITsdxService
{
[OperationContract]
void DoWork();
[OperationContract]
string Test();
}
public class TsdxService : ITsdxService
{
public void DoWork()
{
}
public string Test()
{
return "Hello World!";
}
}
Web.config:
<system.serviceModel>
<services>
<service name="Test.TSDX.UI.TsdxService">
<endpoint
address="Tsdx"
binding="wsHttpBinding"
bindingConfiguration="TestBinding"
contract="Test.TSDX.UI.ITsdxService" />
</service>
</services>
<bindings>
<wsHttpBinding>
<binding name="TestBinding" />
</wsHttpBinding>

<behavior name="">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
When I run from Visual Studio I put localhost:50517/TsdxService.svc?wsdl all works fine - I can see wsdl, but when I put localhost:50517/TsdxService.svc/Tsdx/Test or localhost:50517/TsdxService.svc/Tsdx/DoWork I don't see anything. The Fiddler tells me that I got 400 error. Breakpoints (on Test and DoWork methods) don't work. Why? What did I do incorrect?

Add the WebGet attribute to your service operations.
[WebGet]
public string Test()
{
...
}
For this to work, you also need to add WebScriptEnablingBehavior to the service configuration. Also, use the webHttpBinding. These things are all required to allow the service to work as an AJAX service.
Definition:
<endpointBehaviors>
<behavior name="EndpointBehavior">
<enableWebScript />
</behavior>
</endpointBehaviors>
Reference:
<endpoint behaviorConfiguration="EndpointBehavior"
binding="webHttpBinding"
...
/>
