Here is my .NET Web service code:

[WebMethod]
public double ConvertTemperature(double dFahrenheit)
{
  return ((dFahrenheit - 32) * 5) / 9;
}
[download]

I am using the standard example of Hello World from Visual Studio.NET and I added one more function. I can test this web service locally on my own machine by going directly to the URL (http://localhost/WebService1/Service1.asmx) and I get a web page to load asking me for input and providing a button to invoke.

Is it my machine and the setup?
