Here is my WCF configuratio but when i try to add service reference to

net.tcp://127.0.0.1:8731/IMSSDirectoryService

I get an error:

Metadata contains a reference that cannot be resolved: 'net.tcp://localhost:8731/IMSSDirectoryService'.

If the service is defined in the current solution, try building the solution and adding the service reference again. Please help me to understand my problem.

Solution

You have two identical base addresses defined:

<service name="SUR.Core.Service.Implementation.SURDirectoryService" 
         behaviorConfiguration="DefaultServiceBehavior">
  <host>
    <baseAddresses>
      <add baseAddress="net.tcp://127.0.0.1:8731/ISURDirectoryService"/>
    </baseAddresses>


<service name="MSS.Core.Service.Implementation.MSSDirectoryService" 
         behaviorConfiguration="DefaultServiceBehavior">
   <host>
     <baseAddresses>
       <add baseAddress="net.tcp://127.0.0.1:8731/IMSSDirectoryService"   />

That is the cause of your problems - when connecting to net.tcp://127.0.0.1:8731/, WCF doesn't know which service you mean.

The base address must be UNIQUE within its "schema" (e.g. http, net.tcp etc.)

EDIT: if you want to be able to retrieve your metadata using the browser and navigating to a URL to get it, you'll need to activate the <serviceMetadata httpGetEnabled="True"/> in your service behavior option. Otherwise, you'll only be able to get at your metadata using a SOAP call over net.tcp - e.g. using the "WcfTestClient.exe" app which is in your Visual Studio 9/Common7/IDE folder.

EDIT 2: you have defined a number of extra bindings and behaviors for MEX, but since none of your mex endpoints is actually referencing any of those settings, they're not being used.

I changed the port of ISURDirectoryService it doesn't help, I get the same error message

[marc_s]

How are you trying to get your metadata? Using some SOAP call, or are you trying in the browser?

[Arsen Mkrtchyan]

Browser returns bed request, svcutill tool generates proxy for SUR but in generating MSS i get error, The message with Action 'schemas.xmlsoap.org/ws/2 004/09/transfer/Get' cannot be processed at the receiver, due to a ContractFilte r mismatch at the EndpointDispatcher. This may be because of either a contract m ismatch (mismatched Actions between sender and receiver) or a binding/security m ismatch between the sender and the receiver. Check that sender and receiver hav e the same contract and the same binding (including security requirements, e.g. Message, Transport, None).

[marc_s]

OK - for the browser to be able to see your metadata (which would be a great way to verify everything is ok), enable the serviceMetadata httpGetEnabled setting as I indicated. As for the error with the MSS service - this doesn't sound like a config problem. You'll need to check your SOAP actions and your contracts - something is inconsistent in them. Can you post the service contract definition for the MSS service?

[Arsen Mkrtchyan]

MSS Service contract is big, Is it possible that caouse a problem? I commented all function the wcfclienttest openes the service normally, than I start to open comments, and there is a point after wich, uncommenting even a simple contract method causes the error

[Abhijeet Patel]

I'm having the same problem. I don't want to use mexhttpBinding. I'd like to use mexTcpBinding. The Add Service reference dialog is throwing the error indicated in the post, any clues?
