                                                       Midnight 
 
Assignment:

   In Homework 1 you wrote a GUI that allowed the user to perform
   arithmetic with a remote calculator. In this homework you will build the
   exact same distributed system but using interoperable SOAP rather
   than a Microsoft proprietary protocol.

Requirements:

   Create a virtual directory in IIS that points to a directory holding
   a ".asmx" file. Your remote calculator will be implemented within this
   file in C#. See page 247 of the book.

   From the client's directory, run wsdl.exe on the WSDL that is available from
   your web service. See page 251 of the book. This will create a client side
   proxy.

   Run the GUI client from the client's directory and use the proxy as shown
   on page 252.


Submission:

    Please paste two ".cs" files and one ".asmx" file to blackboard. One ".cs" file 
    will contain your rewritten GUI client. The other will contain your WSDL generated 
    proxy. The ".asmx" file will contain your XML Web Service.                           

    The code that you write must be well documented for full credit.
