Simplify Development

Common Type SystemCommon instance and type definition

Enables clean OO programmingClasses and interfaces

Constructors, properties, methods, eventsCross language inheritance

Built-in interoperabilityWith COMWith native (Win32 style) DLLs

Everything Is An Object

Traditional views of primitive typesC++, Java: Theyre magic Smalltalk, Lisp: Theyre full -blown objects

.NET Framework solution: Value typesunifies with no performance costDeep simplicity throughout system

Improved extensibility and reusabilityNew primitive types: Decimal, SQL Collections, etc., work for all types

How Much Simpler?

Windows APIHWND hwndMain = CreateWindowEx(

0, "MainWClass", "Main Window", WS_OVERLAPPEDWINDOW | WS_HSCROLL | WS_VSCROLL,

CW_USEDEFAULT, CW_USEDEFAULT,CW_USEDEFAULT, CW_USEDEFAULT,(HWND)NULL, (HMENU)NULL, hInstance, NULL);

ShowWindow(hwndMain, SW_SHOWDEFAULT);UpdateWindow(hwndMain);

.NET FrameworkDim form As New Form()form.Text = "Main Window"form.Show()

Factored And Extensible

The Framework is not a black box Any .NET class is available for you to extendthrough inheritance

Gives developers much more head room

Plug and Play components and subsystems
