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 through the process of installing it.

Of course, we will start with the basics, i.e. what is the Microsoft .NET Framework and why is it needed at all?

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, therefore, oddly enough, to a greater extent, the .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 core 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 under 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, they 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 the 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, which, by the way, is the latest version of the .NET Framework that can be installed on Windows XP, and today the version is available. NET Framework 4.5.2.

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

Before proceeding with 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 .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 a MSBuild system for compilation, if you need these components, then you need to already install the full .NET Framework 4. How You probably already understood the .NET Framework 4 client profile is a kind of stripped-down version of the .NET Framework 4.

And now let's move on to installing these components and we will 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 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 installation options - this is through a 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 are no different, just with the first option, we will not have a kind of distribution kit left on our computer, and with the second one 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 connection to the Internet.

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) from 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 do not 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 the 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 press « Install».

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

Installation will not take long, only 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 see this for yourself now.

Installing Microsoft .NET Framework 4.0

To install Microsoft .NET Framework 4.0, we will use the offline installer. 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 are launching it. And also, first we agree with the license agreement, i.e. check the box and click Install»

Then the installation will begin, which will also be very fast.

Click " Ready».

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

Control Panel->Programs and Features

I hope everything was clear. Good luck!

.NET Framework is a software platform released by Microsoft. The basis of the platform is the Common Language Runtime (CLR) execution environment, which is capable of executing both regular programs and server 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:

Version 1.0 at present, it is practically not used anymore, so 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 if necessary, only for those programs that are rigidly tied to it. This is because 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 (as well as programs written under 1.0 can run under version 1.1). To avoid conflicts, it is not recommended to install versions 1.0 and 1.1 at the same time (some entries in the registry are common to them). Versions 1.1 and 1.1 SP1 are included in the Windows Server 2003 and Windows Server 2003 SP1 / R2SP1 / SP2 / R2SP2 operating systems, respectively.

Microsoft .NET Framework 4.7.2

Microsoft .NET Framework 4.5 for Windows 7, download .NET Framework 4.0.30319

The Microsoft .NET Framework is designed to develop and run many programs and applications. The main task of this software platform is to ensure the compatibility of parts of programs written in different languages. This is a set of special services and applications, consisting of the Common Language Runtime (CLR) and the .NET Framework Class Library, which contains ready-made components for working with databases, files, network, etc. You can visit our website using the link at the bottom of the page.

A large number of popular computer programs require the installation of this platform, otherwise they simply will not work. It turns out that the .NET Framework significantly expands the capabilities of the Windows OS and allows applications that were intended for other operating systems to run on Windows. Starting with version 7 of Windows, the Microsoft .NET Framework package is built into the operating system. However, it is advisable to update obsolete resources, and install the final version .NET Framework 4.7.1 for Windows 7 and Windows 10.

Benefits of using .NET Framework:

• manages memory;
• turns all data types into universal components for all applications;
• has a large base of ready-made functions for various operations;
• contains libraries for service and web applications, databases, graphical interfaces and other components;
• provides compatibility between different programming languages.

It should be clarified that Windows XP does not support the new version, in which case you need to download .NET Framework 4.0.30319. The .NET Framework software platform is a very valuable invention of Microsoft specialists, which allows ordinary users to run a variety of software without problems and technical "conflicts", and makes it easier for programmers to work. As a rule, programs written for earlier versions of this platform also function on newer packages, so .NET Framework latest version will ensure the correct operation of all installed software.
