The .NET Framework is a software platform introduced by Microsoft in 2002 for building and running applications. It originally supported only managed and unmanaged applications focused on Windows Forms and ASP.NET. Over time, the .NET Framework has expanded to include support for additional languages and libraries like JavaScript. The current .NET ecosystem includes .NET Framework, .NET Core, Xamarin, and .NET Standard libraries that can be used across components. Popular languages supported by .NET include C#, VB.NET, C++ and J#.

2. Definition :
.NET Framework. .NET Framework. An
application software platform from Microsoft,
introduced in 2002 and commonly called
.NET ("dot net").

3. Scope of . net

4.  Microsoft .Net is today’s leading platform for
window and web based application development.
All things popular will one day face away – this is a
popular belief and technology is not far from it.
Today, not much of these are even seen around.
Technology advances at a fast and new technologies
enter and to replace old one’s.
 Microsoft ASP.NET development today is very
popular and one of the most successful web
development languages. Successful technologies are
one’s that sustain changes as time passes. Take a look
at C language. It still forms the basis of all modern
programming.

5. .NET Framework
When .NET Framework was first introduced,
it supported limited applications. It started
with managed and unmanaged applications
but the managed area was mainly focused
around Win Forms and ASP.NET. Today, if
you look at the architecture of .NET
Framework in the following image, you will
see there is much more added to the
framework, including support of JavaScript
and other libraries.

7.  Let's look at the current ecosystem of .NET. As
shown in the below image, .NET has 5 major
components - Common Infrastructure, .NET
Standard, .NET Framework, .NET Core, and
Xamarin.


9. 1. .NET Framework has traditional .NET
libraries like WPF, Windows Forms, and ASP.NET.
2. .NET Core is open source component and
supports UWP and ASP.NET Core.
3. Xamarin brings mobile development using C#
and F# for I OS, Android, and Windows mobile.
4. .NET Standard library is used as common
libraries for all of the common top layer
components.
5 . Tools, Languages, and Runtime components are
all shared along the top level components.

10.  • VC++
 • VB.NET
 .C#
 • J#
 • JScript .NET

11.  .NET hasn’t traditionally been the Site Point
community’s framework of choice for Web
development. A simple comparison of the
activity within the PHP and the .NET forums
highlights this fact. But with the release
of Site Point’s first ASP.NET book, I thought it
was about time us .NET ers stood proud, and
shouted from the rooftops exactly what makes
this technology so good.

12.  Microsoft . Net is today’s leading platform for

development. All things popular will one day
face away – this is a popular belief and

of all modern programming.

13.  Windows Forms provides a unified
programming model for standard Windows
application development. It does not matter
what language you are using—you can always
be productive because the common substrate
has been developed to benefit all.
 Windows Forms brings a true object-oriented
programming model to Windows GUI
development, allowing for an extensible
framework that is so much cleaner and easier
to use compared to previous attempts.
