Musical Teacher Web Service

A number of people / organizations have developed web services that are available for free to use.

Here is an example of a web service that allows us to search for Music teachers near your zip code. Go to Web Site.

In this example we have a web service up and running. What we need to do is to, generate a proxy code for this service using the Web Services Description Language ( WSDL.EXE ). Develop a Windows or Web application that can use this proxy code to access methods exposed from the web service.

Execute the 2 commands and you are set to go Its that simple and straight.

Here is the SearchMusicTeachers.cs file generated using the WSDL.EXE tool containing the web methods exposed by this service.
