A freely distributed product from Microsoft.Net, the framework is assembled from the .NET Framework class library, which includes classes, interfaces, and the Common Language Runtime, which is available in all compatible programming languages. On this page of the website, following a link from the Microsoft website, it is possible to download Microsoft .NET Framework for free for Windows 7 with service pack SP1, 8, 8.1, 10 and separately for Windows XP SP2 or SP3. Microsoft .NET Framework is a package of services and libraries Class Library with prepared components for interacting with databases, files, network, which guarantees the compatibility and universalization of various software components created in various programming languages ​​based on the technology.Net Framework, and allows you to organize uniform principle of data processing. All CLR functionality can be used in compatible programming languages.

We recommend downloading the Russian version of the Microsoft .NET Framework for free onto your computer, which allows users to use unique innovative software and simplifies the process of creating such software for developers. Languages ​​working in the MS.Net environment: C#, Managed C++, Visual Basic .NET, Delphi for .NET, PascalABC.NET, JScript .NET, Iron Python, Iron Ruby, F# and others.

New technologies

Having at the end of the last century many poorly compatible platforms, environments and technological solutions for creating program code, Microsoft needed to unify the tools for developers. The .NET Framework was able to provide this capability. With it, developers can write applications that run on both Microsoft Windows and Apple Mac OS, Sun Microsystems Solaris, Linux and other OS. An added bonus is that instead of manually entering code, developers can create applications from existing blocks. Many libraries for service and web-oriented applications, databases, program interfaces and other components greatly simplify software development.

In the context of the NGWS (New Generation of Windows Services) strategy, at the end of the 20th and beginning of the 21st centuries, Microsoft took a revolutionary step from focusing on desktops towards mobile and portable devices and web services. Ms.NET The framework has become a powerful competitor to Java from Sun Microsystems, which has a positive impact on the development of IT technologies in the 21st century. Today, no one is surprised by “cloud” solutions, where the storage and transmission of data and program code is carried out by web servers, and not carried out locally on each device. The importance of Microsoft.Net Framework is difficult to overestimate; it has become for the Internet what it is for games. This is confirmed by many positive reviews and comments.

MS.Net Framework solves the problems of security systems, increasing productivity, and increasing stability. You can download the latest version of the Microsoft .NET Framework for Windows XP, Vista, 7, 8, 8.1, 10 (32-bit and 64-bit) on the website using a link from the official Microsoft website at any time. This software framework makes significant improvements in areas such as: Communication Foundation, Workflow Foundation, Identity Foundation and others. Important improvements to C#, Visual Basic and F# speed up the responsiveness of the interface, simplify the development of web-based applications and integration into HTML.

Positive platform Microsoft.Net Framework

Among the advantages are support for innovative industrial standards, a maximum range of programming languages, and the ability to create powerful applications using parallel computing.

Advantages of the Microsoft.Net Framework platform:

Supports a wide range of innovative technologies,
- ensures compatibility of many programming languages,
- retrieves data with maximum performance,
- modifies disparate data into universal data for all applications,
- has a ready-made functional base for various operations,
- increases the productivity of cloud solutions,
- “tailored” for the development of web applications,
- includes AES, SHA-2, ECDH, ECDSA algorithms for encryption,
- automatically collects diagnostic data,
- uses asynchronous handlers,
- uses improved ZIP compression,
- directly manages memory.

It is no coincidence that the emphasis is placed on the fact that you can download the Russian version of the Microsoft .NET Framework for Windows 10, 8.1, 8, 7, Vista, XP (x86 and x64) for free. Microsoft.Net Framework officially works only with Microsoft Windows, however, the Mono, Portable.NET, .NET Compact Framework, .NET Micro Framework, DotGNU, .NET Core and similar projects modify this software platform to work on other operating systems.

The presence of the Microsoft .NET Framework in the system is necessary for the functioning of a program or game that is written using it. Today, many of these have been created, for example, drivers for AMD video cards, the Paint .NET graphics program, KeePass password storage and others. The easiest way is to download Microsoft for free. The download will require about 60 megabytes of available space on your computer's hard drive.

There are situations when the .NET Framework cannot be installed and an installation error occurs. In cases where the Microsoft .NET Framework freezes during installation or the installation stops at the client profile stage, it is worth briefly disabling the always running antivirus.

Microsoft .NET Framework 4.0.30319 is a set of network services and applications actively promoted by Microsoft. Today, .NET has become for the Internet what DirectX is now for the gaming industry, namely, a generally recognized standard. Everyone must download and install .NET in order - more and more often sites and programs simply refuse to work without this package. In a sense, these are a kind of codecs for the Internet and a number of programs :)

If, when installing or launching any program, you see this or a similar message - Error initializing the .NET Framework. To run this application, you must first install the .NET Framework 4 - then download the Microsoft .NET Framework 4.0.30319 web installer and install or update the Microsoft .NET Framework components. Supported 32 x 64 bit OS - Windows XP Service Pack 3, Windows Vista, Windows 7, Windows 7 Service Pack 1, Windows Server 2003 Service Pack 2, Windows Server 2008, Windows Server 2008 R2, Windows Server 2008 R2 SP1.
The Microsoft .NET Framework is designed for programs built on top of the .NET architecture. This architecture is Microsoft's answer to the Java platform. Its purpose is to make Windows applications universal for various operating systems of the Windows family. Thanks to this, programs for Windows XP launch and work correctly on Windows 7, etc.

Peculiarities:

— For 64-bit platforms there is support for arrays larger than 2 GB.
— New model of asynchronous programming.
— A common platform for programming languages ​​that allows you to create cross-platform applications without worrying about specific implementation in operating systems and interaction with computer or mobile device resources.
— Microsoft NET support in application development environments: C#, C++, Visual Basic, Delphi, Pascal and others.
- NET Framework 4.0.30319 has improved performance in several ways.

You can download NET Framework 4.0.30319 for free for Windows 7 and XP operating systems from the link below. Now all applications that require this version will launch and function.

When you launch or install any programs or games, a message appears stating that the system is missing a certain version of the Net Framework. Programs and games can be written in different languages, and even components of the same program can also be written in different programming languages. Hence, in order for the program to work correctly in the operating system, there is a special software platform called Net Framework, developed by Microsoft. Let's try to explain it as clearly as possible - the program code is compiled into some intermediate code that is understandable for the platform and is already executed by it in the operating system.

How to download net framework for windows XP

There are four ways to install the framework:

1. In particular, it may be contained in the operating system itself during installation.
2. Can be installed manually from the official Microsoft website.
3. The third method is to install it on the system along with automatic updates.
4. The fourth method - sometimes it can go along with some program.

There is no need to launch or configure Net Framework in any way; it works completely automatically. The problem may be that not all new releases of the No Framework may include older components. In this case, it is better to have several versions installed. There is also the problem of incompatibility of new operating systems with old versions of frameworks, and old operating systems do not support new versions. Such as Windows XP, which supports No Framework only up to version 4.0 inclusive.

How to download net framework 4 for windows XP

As already written above, there are several ways to download and install the Framework on a computer running Windows XP. Let's look at how to install the Framework manually.

• To do this, go to the official Microsoft website.

• Download the Net Framework 4 installer.

• Then double-click on the downloaded file in the folder to start the installation.

• We agree to the terms of the license agreement and confirm the installation.

• Next, the whole process will be automated, lasting about 2 minutes, wait until the installation is complete. Then restart your computer.

You can also install the Microsoft .NET Framework package using third-party software; this is a program for installing and updating drivers DriverPack Solution, which, along with all the necessary drivers and utilities, will install the appropriate version of the framework on your computer.

Probably every user of the Windows operating system has come across such a concept as Microsoft .NET Framework, but not everyone knows what it is, what it is for, where to download it and how to install it, so now we will look at all this and install Microsoft .NET Framework 4.0 on Windows 7 as an example.

In addition to everything else, we will learn what the Microsoft .NET Framework 4 Client Profile is and also look at the process of installing it.

We will of course start with the basics, i.e. What is the Microsoft .NET Framework and why is it needed?

What is the Microsoft .NET Framework and what is it for?

.NET Framework is a platform that serves to create and run applications and web services. The developer is Microsoft, so, oddly enough, the .NET Framework was created and designed for the Windows operating system, but there are also projects that allow you to run .NET programs in other operating systems, for example, Linux.

The main components of the .NET Framework are the runtime (CLR) and class library, which includes ADO.NET, ASP.NET, Windows Forms, and Windows Presentation Foundation (WPF). The development environment is primarily Microsoft Visual Studio, which is understandable, since VS development is also a Microsoft company, and in this case the programming languages ​​are: C#, Visual Basic .NET, C++. But just as mentioned above, there are also independent projects in which you can write programs for the .NET Framework in other languages.

For ordinary users, to put it simply, the Microsoft .NET Framework is just a program or component of the operating system, without which programs or games written under the .NET Framework simply will not work, will not even start. Therefore, if anyone doubts whether the Microsoft .NET Framework program is needed or not, then the answer, of course, is needed, since in the modern world there are a huge number of programs and games that use the .NET Framework libraries. And if you have not yet encountered programs or games that require installation of the Microsoft .NET Framework, then sooner or later you will encounter this. And if we talk about which version to install, then, of course, the newer the better, for example we will install version 4.0, this, by the way, is the latest version of the .NET Framework that can be installed on Windows XP, and the version is available today. NET Framework 4.5.2.

Note! As can be seen from the title of the material, we will install Microsoft .NET Framework 4.0 on the Windows 7 operating system; by the way, by default it already has .NET Framework 3.5 installed, in Windows 8 the default version is 4.0, and in Windows 8.1 it is already 4.5. Therefore, if you have, for example, Windows 8, then you do not need to install .NET Framework 4.0.

Before moving on to the installation, let's talk about the so-called Microsoft .NET Framework 4 Client Profile.

.NET Framework 4 Client Profile

.NET Framework 4 Client Profile is a subset of .NET Framework 4 components that are optimized for client applications. It includes the necessary set of functions and components that are sufficient for most client applications. This includes Windows Presentation Foundation (WPF), Windows Forms, Windows Communication Foundation (WCF). If we talk about what is not included here, then this is: ASP.NET, an extended set of WCF functions, a .NET Framework data provider for Oracle and an MSBuild system for compilation, if you need these components, then you need to already install the full .NET Framework 4. How You probably already understand that the .NET Framework 4 client profile is sort of a stripped-down version of the .NET Framework 4.

And now let's move on to installing these components and we'll start with the Microsoft .NET Framework 4 Client Profile.

Note! If you want to immediately install the full-fledged Microsoft .NET Framework 4.0, then it is not necessary to install the client profile.

Installing Microsoft .NET Framework 4 Client Profile

And in order to install this component, you must, of course, download it, and this can be better done from the official Microsoft download center.

There are two possible installation options: via the web installer, i.e. we downloaded a small program and launched it, and it will already download all the necessary components and the second option is the so-called offline (classic) installation in which we download the full package and then install it. In principle, they are no different, it’s just that with the first option we won’t have some kind of distribution left on our computer, but with the second we will have it. At the same time, we can transfer it and install it on a computer that is not connected to the Internet; in turn, the web installer requires an Internet connection.

I suggest installing the .NET Framework 4 client profile using the web installer, and then using the offline installer when we look at installing the full .NET Framework 4.0.

So, let's begin.

You can download the .NET Framework 4 client profile (web installer) on this page.

You go to the page and click " Download»

Then you will be asked to check additional application packages for download, but since in this case we don’t need anything else, we just click “ Refuse and continue» on the right side of the screen

As a result, you will download the file dotNetFx40_Client_setup.exe, which needs to be launched.

And immediately after launch we need to agree to the license agreement, i.e. check the box next to " I have read and accept the terms of the license agreement" and press " Install».

Then we don't need to do anything else, we just wait for the download and installation to finish.

The installation will not take much time, only about 3 minutes, after which the installer will say that “ Installation completed", and we press " Ready».

As you can see, there is nothing complicated in installing the .NET Framework 4 client profile, as well as in installing the Microsoft .NET Framework 4 platform itself, but you will now see this for yourself.

Microsoft .NET Framework is a computer software platform released by Microsoft in 2002. The basis of the platform is the CLR (Common Language Runtime), which is capable of running both regular programs and server-side web applications.

The Microsoft .NET Framework supports the creation of programs written in different programming languages.

It is believed that the Microsoft .NET Framework platform was Microsoft's response to the Sun Microsystems (now owned by Oracle) Java platform, which had become very popular by that time.

The main idea behind the development of the Microsoft .NET Framework was to provide developer freedom by giving him the ability to create different types of applications that can run on different types of devices and in different environments. The second principle was the focus on systems running the Microsoft Windows family of operating systems.

List of Microsoft .NET Framework versions

The first release of the Microsoft .NET Framework was released on January 5, 2002 for Microsoft Windows 98, Microsoft Windows NT 4.0, Microsoft Windows 2000, and Microsoft Windows XP. General support from Microsoft ended on July 10, 2007, and extended support ended on July 14, 2009.

The next release of the Microsoft .NET Framework was released on April 1, 2003. This was the first version that was automatically installed with the operating system (Microsoft Windows Server 2003). For older operating systems, Microsoft .NET Framework 1.1 was available as a separate installation package. General support from Microsoft ended on October 14, 2008, and extended support ended on October 8, 2013.

Version 2.0 was released simultaneously with Microsoft Visual Studio 2005, Microsoft SQL Server 2005 and Microsoft BizTalk 2006. With the release of version 2.0, support for custom (generic) classes, anonymous methods, full support for 64-bit x64 and IA platforms was added -64.

Initially, Microsoft .NET Framework 3.0 was named WinFX, which reflected its essence: an extension of Microsoft .NET Framework 2.0 with the preservation of all libraries and the addition of four new components:

Like version 3.0, Microsoft .NET 3.5 uses CLR version 2.0. New features compared to Microsoft .NET Framework 3.0 include:

Microsoft announced the Microsoft .NET Framework 4.0 on September 29, 2008. The first beta version appeared on May 20, 2009, along with the beta version of Microsoft Visual Studio 2010. New features include:

• Parallel Extensions – PLINQ (Parallel LINQ) and the Task Parallel Library, designed to simplify programming for multiprocessor and distributed systems;
