Consuming Web services with Microsoft .NET

Part of BookMARC's TVS Model papers.

The new Microsoft development platform has a simple and straightforward way to consume webservices.

In the next steps we will see how this is done:

  1. Start by opening Visual Studio .NET
  2. Create a Windows Application Project
  3. Under the Solution Explorer right-click on the solution name and choose Add Web Reference
  4. Type the address where the web service is located:
  5. We can choose the option View Contract to look at the web service description
  6. Add the web reference
  7. Add controls to the form, to get user input and display the results, and code to execute the services
  8. See the services description bellow for some code examples


Visual Studio .NET doesn't includes a TCP monitor. The Axis monitor can be used instead or you can download the Microsoft SOAP Toolkit from and use its Trace Utility.

If you're going to use the Axis monitor see Axis Monitoring.

Using the Microsoft SOAP Toolkit Trace Utility

  1. Execute the Trace Utility
  2. Add a new Formated Trace
  3. In the Trace Setup add the following values:
    1. Local port # - select a local port to be monitored (example: 9090)
    2. Destination host -
    3. Destination port - 80
    4. Click Ok
  4. The monitor is ready, now we have to make a small change to the generated code:
    1. Open the Reference.vb file which is located in the project directory under Web References\ and change the Me.Url variable value to: http://localhost:9090/sirius/sirius2.exe
    2. Now we can see the SOAP request and the service SOAP response
