XML Web Development Overview

.NET Framework extends the operating system using web services. These web services allow distributed computing that exposes distributed services. We can share class created in separate namespaces; examples would be priceline or expedia that are sharing data and classes through these exposed classes. The biggest benefit of .NET Framework is the use of Garbage Collection. This garbage collection helps stop memory leaks by destroying objects. This speeds up the work environment for your web service and frees' up the programmer from creating destructor classes to dispose of objects. TERMS: CLR - Common Langauge Runtime MSIL - Intermediate Code MCTS - Microsoft Certified Technology Specialist 70-529 PE - Portable Executable Reflection - CLR that is able to compare or mimic classes exposed Managed Code - has garbage collection with double compile Un-Managed Code - no garbage collection with single compile Advantages of .NET WebServices

1. Services that are "black-box" technology that can be added easily through XML without worrying about how the supporting service is implemented.
2. XML WebServices are designed to interact with applications that do not have a traditional interface or any interface what so ever.
3. .NET uses standard protocols and data formats as HTTP, XML and Simple Object Oriented Protocol (SOAP).

Namespace: Controls Classes

Classes: definitions surrounding a set of instructions

Methods: classes can have methods. Method is a structure that contains instructions
