Creating the MathWebService

The first task is to build an XML web service that can be utilized by a workflow-enabled application.

To do so, create a brand-new XML web service project by accessing the File ➤ New Web Site menu

option. Select the ASP.NET Web Service icon and be sure to select the HTTP location option in order

to create this web service within a new IIS virtual directory mapped to http://localhost/

MathWebService (see Figure 26-11).

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

public class MathService : System.Web.Services.WebService

{
