How to get WSDL for a netTcpBinding WCF

Question

 

Hello,

 

Can someone pls let me know how to create a WSDL for a WCF service which has netTcpBinding and hosted as a windows service?

 

Thanks,

Rathi

Answer 1

You have to create a mexNetTcpBinding endpoint, set the contract on it to IMetadataExchange, and enable "serviceMetadata" in the service behavior.  An example of this:

 

 

Code Snippet

<services>
   <service
    name="MyService"
    behaviorConfiguration="myBehavior">
    <host>
     <baseAddresses>
      <add baseAddress="net.tcp://localhost:9000/MyService"/>
     </baseAddresses>
    </host>
    <endpoint
     name="netTcp"
     address=""
     binding="netTcpBinding"
     bindingConfiguration="secure"
     contract="IIMyService">
    </endpoint>
    <endpoint
     name="mexNetTcp"
     address="net.tcp://localhost:9001/CommMgr/mex"
     binding="mexTcpBinding"
     contract="IMetadataExchange">
    </endpoint>
   </service>
  </services>
  <behaviors>
   <serviceBehaviors>
    <behavior name="myBehavior">
     <serviceMetadata />
    </behavior>
   </serviceBehaviors>
  </behaviors>

 

Answer 2

So after adding this end point, can i be able to see the wsdl in this url net.tcp://localhost:9001/CommMgr/mex

?

 

Thanks,

Answer 3

Yup.  You will need to change the contracts and things to match yours, but this is the jist of it.

Answer 4

Hi, below is my configuration.

 

<system.serviceModel>

<services>

<service name="WCFServiceLibrary.service1" behaviorConfiguration="ServiceBehavior">

<host>

<baseAddresses>

<add baseAddress="net.tcp://localhost:5000/WCFServiceLibrary/service1"/>

</baseAddresses>

</host>

<endpoint address=""

binding="netTcpBinding" bindingConfiguration ="secure"

contract="WCFServiceLibrary.IService1" />

<endpoint

name="mexNetTcp"

address="net.tcp://localhost:5001/WCFServiceLibrary/mex"

binding="mexTcpBinding"

contract="IMetadataExchange">

</endpoint>

</service>

</services>

<behaviors>

<serviceBehaviors>

<behavior name ="ServiceBehavior">

<serviceDebug includeExceptionDetailInFaults="true"/>

<serviceMetadata/>

</behavior>

</serviceBehaviors>

</behaviors>

</system.serviceModel>

 

 

After adding the endpoint for metadata, i am not able to connect to the service at all. Can u let me know what the issue is?

 

Thanks,

Rathi

Answer 5

Well for one you have no binding configuration so remove "bindingConfiguration ="secure""

Answer 6

Am getting the below issue now.

 

There was no endpoint listening at net.tcp://localhost:5000/WCFServiceLibrary/service1 that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

 

And here is the config details:

 

Host Config:

 

<services>

<service name="WCFServiceLibrary.service1" behaviorConfiguration="ServiceBehavior">

<host>

<baseAddresses>

<add baseAddress="net.tcp://localhost:5000/WCFServiceLibrary/service1"/>

</baseAddresses>

</host>

<endpoint address=""

binding="netTcpBinding"

contract="WCFServiceLibrary.IService1" />

<endpoint

name="mexNetTcp"

address="net.tcp://localhost:5001/WCFServiceLibrary/mex"

binding="mexTcpBinding"

contract="IMetadataExchange">

</endpoint>

</service>

</services>

<behaviors>

<serviceBehaviors>

<behavior name ="ServiceBehavior">

<serviceDebug includeExceptionDetailInFaults="true"/>

<serviceMetadata/>

</behavior>

</serviceBehaviors>

</behaviors>

 

 

and client config:

 

<system.serviceModel>

<client>

<endpoint binding ="netTcpBinding" name ="HBOSTest" address ="net.tcp://localhost:5000/WCFServiceLibrary/service1" contract ="WindowsApplicationTestWCF.IService1"></endpoint>

</client>

</system.serviceModel>

 

 

Answer 7

That address is correct.  Make sure your sevice is running or maybe run WcfTestClient.exe against that address to make sure it is running.

 

Answer 8

I could not figure out what the issue is, but the windows service is started and running..

 

it was working fine..

 

 

 

Answer 9

Can someone tell me, i can get the WSDL for a tcp binding service only on .NET 3.5 / VS2008?

 

Thanks,

rathi

Answer 10

No this will work in .Net 3.0 and/or VS2005.  Once you have the metadata exchange endpoint setup you can navitate to it in the web browser or whatever and see the wsdl being generated.

Answer 11

am getting the issue that the service contract IMetaDataEndpoint is not available in the service name when i tried.Any ideas??

 

Thanks,

Rathi

 

Answer 12

hi,

 

I have got the issue solved. I need to specify a http url in the base address section of the host. Attached the server (host) configuration file.

 

Thanks,

Rathi

 

 

<configuration>

<system.serviceModel>

<services>

<service name ="WcfServiceLibrary.Service1" behaviorConfiguration ="Sbehavior">

<host>

<baseAddresses>

<add baseAddress="http://localhost:5002/WcfServiceLibrary/mex"/>

<add baseAddress ="net.tcp://localhost:5001/WcfServiceLibrary/Service1"/>

</baseAddresses>

</host>

<endpoint address ="" binding ="netTcpBinding" contract ="WcfServiceLibrary.IService1"></endpoint>

<endpoint address ="net.tcp://localhost:5001/WcfServiceLibrary/mex" binding ="mexTcpBinding" contract ="IMetadataExchange"></endpoint>

</service>

</services>

<behaviors>

<serviceBehaviors>

<behavior name ="Sbehavior">

<serviceDebug includeExceptionDetailInFaults ="true"/>

<serviceMetadata httpGetEnabled ="true"/>

</behavior>

</serviceBehaviors>

</behaviors>

</system.serviceModel>

</configuration>

Answer 13

Hi Rathi,

Thanks for such a Nice Blog.

I have one question here, i am getting one error when i tried to host both nettcp address and mexNetTcp address on the same port. R u getting this error?.

And are you able to access the WSDl from "net.tcp://localhost:5001/WcfServiceLibrary/mex" , because i am not.

Please find below my app Config details

<services>


<service name="TransactionImplementer"

behaviorConfiguration="ServiceBehavior">

<host>

<baseAddresses>

<add baseAddress="net.tcp://localhost:9001/services/CommonOperations" />

<add baseAddress="http://localhost:8001/services/CommonOperations/mex"/>

</baseAddresses>

</host>

<endpoint address=""

binding="netTcpBinding"

bindingConfiguration="BasicTCP"

behaviorConfiguration=""

contract="ITransactionImplementer"

name="ITransactionImplementer" >

<identity>

<dns value="localhost"/> 

</identity>

</endpoint>



<endpoint address="net.tcp://localhost:9002/services/CommonOperations/mex" 

binding="mexTcpBinding"

behaviorConfiguration=""

contract="IMetadataExchange" 

name="IMetadataExchange"/>


</service>

 

Your Quick response will be highly appreciated.
