Generating WCF Proxy using SvcUtil.exe

7 08 2008

Visual Studio 2008 has made our WCF life a lot easier with the ability to self-host the services and also allow debugging in our service.

What if we were pushed to a situation wherein we need to use the tool svcutil.exe to create our proxy for the client…hmm… :)

To do so, we need to have our service running. Once the service is up and running, we could generate the proxy by the following command (replace the tags correspondingly) :

   1: svcutil /t:code http://<service_url> 
   2:       /out:<file_name>.cs /config:<file_name>.config

Here is my example :

   1: C:\Users\Chaks\Documents\Visual Studio 2008\Projects\MyService\MyServiceHost>
   2: svcutil /t:code http://localhost:8731/Design_Time_Addresses/MyService/WcfService/ 
   3: /out:MyServiceProxy.cs /config:MyServiceProxy.config
   4: Microsoft (R) Service Model Metadata Tool
   5: [Microsoft (R) Windows (R) Communication Foundation, Version 3.0.4506.648]
   6: Copyright (c) Microsoft Corporation.  All rights reserved.
   7:  
   8: Attempting to download metadata from 'http://localhost:8731/Design_Time_Addresse
   9: s/MyService/WcfService/' using WS-Metadata Exchange or DISCO.
  10: Generating files...
  11: C:\Users\Chaks\Documents\Visual Studio 2008\Projects\MyService\MyServiceHost\MyS
  12: erviceProxy.cs
  13: C:\Users\Chaks\Documents\Visual Studio 2008\Projects\MyService\MyServiceHost\MyS
  14: erviceProxy.config

Now we can add this .cs file to the Client project and copy the .config file contents to the Client’s app.config file and execute the client 8)

We can also instruct svcutil to generate the proxy in the preferred language we want :

   1: svcutil /t:code /language=VB 
   2:      http://localhost:8731/Design_Time_Addresses/MyService/WcfService/ 
   3:          /out:MyServiceProxy.vb /config:MyServiceProxy.config

But svcutil already identifies the language with the extension of our output file name 8)

Very nice article! It partially solves my problem.

Is it possible to:

1) Tell the tool that I want to generate asynchronous operations
2) Change the collection type to say Systems.Collection.Generic.List
3) Tell the tool that I want to reuse all reference types?

I’m trying to automate the “Update Service Reference” IDE command and the 3 steps above reflect the way I normally configure a WCF service.

Any help is appreciated, thank you in advance.

Daniel.

You should give the parameter “/language:vb” .
If you call svcutil like that you’ll get a file “MyService.vb.cs”

Using add service reference gives error sometime, particularly when dealing with TFS. Use SvcUtil.exe to manually generate web service and WCF Services proxies.
