Exercises

1. Create a new ASP.NET Web application and duplicate the functionality of the Windows Forms application you created earlier today.
2. Create a new Web service named MathService. Add a function that accepts two numeric values and returns a numeric value that's the result of multiplying the two input values.

3. Create a new Web service that has all the data from the Customers table and the Orders table in the Northwind database. The DataSet that's returned should have both tables.

   Next, create a Windows Form application, consume the Web service, and bind it to a DataGrid.

   Observe the difference in the DataGrid as the result of binding the results of a DataSet from a Web service with two tables in a DataSet. What is the difference?
