errors in wcf web.config file

Question

I'm working on wcf service and I am very new to this. Here I had made some changes in web.config file according to the videos I had watched, but the following error had occurred and I don't know that what it is exactly asking.

Can any one please help me to solve this?

This is the error I am getting

Error: Cannot obtain Metadata from http://localhost:15305/Techieez.svc

If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address. For help enabling metadata publishing, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata

Answer 1

That's not necessarily an error, it just means you cannot access the service metadata which is often done for security reasons. Your service may still work fine (assuming you've done the other 10,000 things you need to do to make WCF work), you would just need to know how to connect from the client without relying on, for instance, "Add Service Reference" from visual studio. But to enable the service metadata, add this endpoint to the <service>:

<endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex"/>

Answer 2

   <endpoint address="" binding="basicHttpBinding" bindingConfiguration=""
      contract="TechieezService.ITechieez" />

You don't have a behavior specified for the basicHttpBinding, which looks like the one that would be used if you go to the url you have listed. You have a behavior that allows you get the metadata, but you aren't using it. Try changing it to this:

   <endpoint address="" behaviorConfiguration="DefaultBehaviour" 
   binding="basicHttpBinding" bindingConfiguration="" 
   contract="TechieezService.ITechieez" />
