Download microsoft net version 4.0. What is Microsoft .NET Framework. How to install and reinstall NET Framework

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 walk you through the installation process.

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

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

.NET Framework Is a platform that is used to build and run applications and web services. The developer is Microsoft, therefore, oddly enough, to a greater extent .NET Framework was created and designed for the Windows operating system, but there are also projects that allow you to run .NET programs on other operating systems, such as 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 from Microsoft, 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, speaking in a simple way, Microsoft .NET Framework is just a program or component of the operating system, without which programs or games written for the .NET Framework simply won't work, won't even start. Therefore, if anyone doubts whether a Microsoft .NET Framework program is needed or not, then the answer, of course, is needed, since in the modern world there is a huge number of programs and games that use the .NET Framework libraries. And if you still have not encountered programs or games that require the installation of Microsoft .NET Framework, then sooner or later you will come across this. And if we talk about which version to install, then, of course, the newest, the better, for example, we will install version 4.0, by the way, this is the latest version of the .NET Framework that can be installed on Windows XP, and today a version is available. NET Framework 4.5.2.

Note! As you can see from the name of the material, we will install Microsoft .NET Framework 4.0 on the Windows 7 operating system, by the way, by default .NET Framework 3.5 is already installed in it, 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 .NET Framework 4.0 does not need to be installed.

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

.NET Framework 4 Client Profile is a subset of the .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, these are: ASP.NET, an extended set of WCF functions, the .NET Framework data provider for Oracle and the MSBuild system for compilation, if you need these components, then you need to already install the full-fledged .NET Framework 4. How You probably already figured out 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, you do not need 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 done better from the official Microsoft download center.

There are two possible options for installing it through 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 standalone (classic) installation in which we download the full package and then install it. In principle, they do not differ in any way, just with the first option, we will not have a kind of distribution kit on our computer, and with the second option, we will have it. At the same time, we will be able to transfer and install it on a computer that is not connected to the Internet, in turn, the web installer requires a mandatory Internet connection.

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

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 mark 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 to run.

And immediately after launch, we need to agree with the license agreement, i.e. check the box next to " I have read and accept the terms of the license agreement"And click" 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 3 minutes, after which the installer will say that “ Installation completed"And we press" Ready».

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

Installing Microsoft .NET Framework 4.0

We will use the offline installer to install Microsoft .NET Framework 4.0. You can download it here.

Also click " Download"And if we do not want to install something additional, then click" Refuse and continue»

We will download the file dotNetFx40_Full_x86_x64.exe we launch it. And also first we agree with the license agreement, i.e. put a tick and click " Install»

Then the installation will start, which will also go very quickly.

We press " Ready».

Now Microsoft .NET Framework 4.0 is installed on our computer, by the way, we can see it in the list of installed programs, namely

Control Panel-> Programs and Features

I hope everything was clear. Good luck!

  This version of Microsoft .NET Framework 4 does not support the Server Core installation of Windows Server 2008 and Windows Server 2008 R2. To get a version of Microsoft .NET Framework 4 that supports the Server Core installation option of Windows Server 2008 R2 SP1, go to

Microsoft .NET Framework is a software framework that supports the creation and execution of other desktop and web applications on OS Windows from its 98th build.

The main focus of this platform is the compatibility of various applications written in different programming languages.

Downloading and updating Microsoft .NET Framework is recommended for those Windows users who have errors during the installation of any programs or games.

Features of the platform:

allows you to achieve compatibility of services written in different languages and in different environments;
independently take care of basic security, memory management and the list of exceptions while working with programs;
identifies and loads only those components that are applicable and necessary for a particular system;
does not require any settings from the computer user.

The purpose of creating the Microsoft .NET Framework was the task of giving the developers of various software the maximum freedom of action for their creativity.

Microsoft .NET Framework allows most programs to run on modern Windows operating systems. Therefore, its installation will be necessary for all users. Starting with the Windows 7 operating system, Microsoft has included this tool in the distribution and installs it automatically during installation.

Download NET Framework 3 ..

Not to worry about the language in which a particular utility is executed, its architecture, system bitness or assembly - it was decided to assign the mission of compatibility of applications of various types to this software environment.

The principle of performing the task in stages:

Starting a service or process.
Conversion of the language used by the compiler into a single bytecode.
Execution or translation of code for a specific target process or service.

It should be understood that the latest latest version of the Microsoft .NET Framework does not replace the previous one in all cases. It is also important that new builds of Windows operating systems do not support older versions of this tool.

It is recommended to update Microsoft NET Framework to the latest version for all users of Windows 7, 8 and 10 of any bitness.

So, if 4.0 is installed, but 3.5 is not, and the program needs the previous one, then it will not start working without the necessary one. At the same time, 3.5 already includes 2.0 and 3.0, so sometimes it's better to install it. And XP from Microsoft only supports the software platform up to 4.0. Therefore, when installing, for example, a game that requires a new version of the Microsoft .NET Framework, you will have to reinstall the entire OS or look for another alternative to the game.

It should be noted that Microsoft does not recommend that users install multilingual versions of this software environment on their PCs. In such cases, conflicts and incorrect operation of utilities are possible. If the need arises, it is better to remove the already installed one and install the new one.

Net Framework is a software platform for executing applications developed in an appropriate environment. It is a kind of analogue of Java from the currently owned Oracle Sun Microsystems and is also necessary for the development of these same programs. The engine is based on the common language runtime of the CLR code, which is compatible with various languages. The Framework works in a number of operating systems from Microsoft 32 bit / 64 bit. These include:

Windows 7;
Windows 8.1;
Windows 10.

XP is no longer supported by the latest version of the platform.

Features of the 4th version

The new development of Net Framework 4.0.30319 was introduced in 2010 and differs from the third version in the following points:

support for new commands and operations in Visual Basic;
availability of MEF support;
IronRuby and IronPython compatibility;
the presence of modeling tools and a special programming language required for the formation of domain-specific models.

The link below will help you download the fresh Framework for free. The installed software product is critical for the proper functioning of the Internet connection and for most applications using the network. All in all, Net Framework is becoming the global standard for the networking industry, which is what DirectX or ActiveX is for running computer games.

Compared to the most progressive version of Java, Net Framework is distributed without registration and shows exactly 300% better performance. This allows you to create high-quality and complex products, consisting of several modules, faster, and their performance will be high even on older computers. Development speed is accelerated by the presence of many out-of-the-box functions, classes, and visually presented tools. New developers of multi-platform applications can download this Framework for free.

Disadvantages and limitations

Running applications developed using this technology on a weak laptop, despite the higher work efficiency compared to Java, consume more resources than less popular counterparts.

The absence of obfuscation or obfuscation of the code makes it easy to decompile (decrypt) the application and interfere with its code, which promises the loss of trade secrets and disclosure of the mechanisms of work of the cracked software.

Microsoft limited the cross-platform implementation of the Framework, which is why it is present on other platforms, but in an obviously truncated form, that is, with less functionality.

You can install NET Framework for any computer by downloading the installer from our website.

.NET Framework Is a software platform released by Microsoft. The platform is based on the Common Language Runtime (CLR), which can run both regular programs and server-side web applications. The .NET Framework supports the creation of programs written in different programming languages. The platform is necessary for the installation and correct operation of many programs, therefore it is necessary for users.

System requirements:

Windows XP (1.1 - 3.5) | Vista | 7 | 8 | 8.1

Russian language only in the installer

Version 1.0 nowadays it is practically not used any more, therefore it is recommended to install it only when necessary, when working with programs that require it (Visual Studio 2002, Sound Forge of some versions, etc.). Version 1.1 does not include version 1.0, does not require or replace it during installation. It is used more often, but it is also recommended to install it as needed, only for those programs that are rigidly tied to it. This is due to the fact that the .NET Framework 2.0 package provides backward compatibility with previous versions, and most programs written under 1.0 and 1.1 work without problems in the 2.0 environment (just as programs written under 1.0 can run under 1.1). To avoid conflicts, it is not recommended to install versions 1.0 and 1.1 at the same time (they have some common registry entries). Versions 1.1 and 1.1 SP1 are included with Windows Server 2003 and Windows Server 2003 SP1 / R2SP1 / SP2 / R2SP2, respectively.
