Ø You
should understand that the .NET Framework is really a cluster of several
technologies:
Ø The .NET languages:
These include C# and VB .NET
(Visual Basic .NET), the object-oriented and modernized successor to Visual
Basic 6.0; these languages also include JScript .NET (a server-side version of
JavaScript), J# (a Java clone), and C++ with Managed Extensions.
Ø The CLR (Common Language Runtime):
The CLR is the engine that executes all .NET programs and provides automatic
services for these applications, such as security checking, memory management,
and optimization.
Ø The .NET Framework class library:
The class library collects thousands of pieces of prebuilt functionality that
you can “snap in” to your applications. These features are sometimes organized
into technology sets, such as ADO.NET (the technology for creating database
applications) and Windows Forms (the technology for creating desktop user
interfaces).
Ø ASP.NET:
This is the engine that hosts web applications and web services, with almost
any feature from the .NET class library. ASP.NET also includes a set of
web-specific services.
Ø Visual Studio:
This optional development tool contains a rich set of productivity and debugging
features. The Visual Studio setup CDs (or DVD) include the complete .NET
Framework, so you won’t need to download it separately.
