Failed to add a service. Service metadata may not be accessible. Make sure your service is running and exposing metadata.`

Question

EDIT:

After I modified the web.config and I don't get error that's good.... then I add a new page (html) and write this small code to consume the service like this:

 $("#btn12").click(function (event) {                 $.getJSON('http://localhost:3576/MyService.svc/GetCurrentUser', {},                 function (data) {                     alert(data);                 });                 //return false;             }); 

I see the following error in my FireBug:

http://localhost:3576/MyService.svc/GetCurrentUser 400 Bad Request 

Note: I have added html page on the same wcf project and running the project it self so I am assuming the service is also running ...

What might be wrong here?

END EDIT

I have just created a new wcf services and when I hit f5 from VS and I get this error in WCF Test Client window :

You need to add a metadata exchange (mex) endpoint to your service:

<services>    <service name="MyService.MyService" behaviorConfiguration="metadataBehavior">       <endpoint            address="http://localhost/MyService.svc"            binding="customBinding" bindingConfiguration="jsonpBinding"            behaviorConfiguration="MyService.MyService"           contract="MyService.IMyService"/>       <endpoint            address="mex"            binding="mexHttpBinding"            contract="IMetadataExchange"/>    </service> </services> 

Now, you should be able to get metadata for your service

Update: ok, so you're just launching this from Visual Studio - in that case, it will be hosted in Cassini, the built-in web server. That beast however only supports HTTP - you're not using that protocol in your binding...

Also, since you're hosting this in Cassini, the address of your service will be dictated by Cassini - you don't get to define anything.

So my suggestion would be:

• try to use http binding (just now for testing)
• get this to work
• once you know it works, change it to your custom binding and host it in IIS

So I would change the config to:

<behaviors>    <serviceBehaviors>       <behavior name="metadataBehavior">          <serviceMetadata httpGetEnabled="true" />       </behavior>    </serviceBehaviors> </behaviors> <services>    <service name="MyService.MyService" behaviorConfiguration="metadataBehavior">       <endpoint            address=""   <!-- don't put anything here - Cassini will determine address -->           binding="basicHttpBinding"            contract="MyService.IMyService"/>       <endpoint            address="mex"            binding="mexHttpBinding"            contract="IMetadataExchange"/>    </service> </services> 

Once you have that, try to do a View in Browser on your SVC file in your Visual Studio solution - if that doesn't work, you still have a major problem of some sort.

If it works - now you can press F5 in VS and your service should come up, and using the WCF Test Client app, you should be able to get your service metadata from a) the address that Cassini started your service on, or b) the mex address (Cassini's address + /mex)
