1) What is the difference between the System.Net namespace and the System.Web
System.Web - is used for creating web services on the server.

3) What is the differences between a SOAP Web Service and a REST Web Service ?
SOAP - describes itself using a wsdl (web description language) and has a defined contract
REST - lightweight http protocol that can return different formats (text, html, xml)

4) How can you return an error from a SOAP Web Service ?

5) Write a function that takes a date and returns the quarter that the date is in ?

public static int GetQuarter(System.DateTime myDateTime) 
{ 
   return System.Convert.ToInt32(System.Math.Ceiling(myDateTime.Month(3D)); 
} 

The "D" literal number suffix tells the compiler that the literal value passed to the Month method is of data type double.
You can use this when you want an integer number to be treated as a double.
