Microsoft net framework 4.5.2 what is it for. Microsoft net Framework - what kind of program is it? What is Microsoft.NET Framework and what is it for?

The Microsoft .net framework is a Windows OS-integrated, consistent, and comprehensive programming model. It is used to create software high quality, provided with an excellent interface, and is characterized by security and transparency of network connections.

The core of the platform is a multilingual programming environment called the Common Language Runtime (CLR). It is believed that the framework was developed as a response to the then popular Java platform from Sun.

Why install it?

When one of the applications or games during installation requests the installation of the microsoft .net framework, not many agree, not understanding why this is needed. Some users do not install the package that comes with it because they already have one of the frameworks installed.

However, both of them are wrong. It is imperative to install exactly the version (v4.0, 2.0, 3.5, 4.5) of the microsoft .net framework that this or that application requires. Because it will only work stably on the platform on which it was developed, even if you have the latest version of the software package installed.

This relationship between applications and the platform is explained very simply. This is done so that the developer is not tied to the operating system and the user's processor capacity. For example, if a program created on a platform version v4.0, 2.0, 3.5, 4.5 was launched on a PC, support (or implementation) must be installed in the form of software microsoft software.net framework v4.0, 2.0, 3.5, 4.5.

Important components

You need to know that the microsoft .net framework consists of two parts:

• performer's environment;
• plug-in library.

The main component can be called the Common Language Runtime (CLR). It can execute the software part of regular applications or server ones, being a runtime environment.

The other half is needed no less. Framework Class Library (FCL) is a class library that contains quite a lot of elements to handle:

• databases;
• networks;
• interfaces;
• files;
• input and output of data.

All this allows the developer to use ready-made classes to create programs, bypassing the low-level part.

Installing platform support

The microsoft .net framework installer is added to OS windows by default. Platform version v4.0, 2.0, 3.5, 4.5 depends on the operating system. But almost any of them can be installed independently if necessary, if your computer meets the requirements.

.Net platform requirements

As is the case with any applications, the .Net platform also has its own requirements for normal program support. How newer version microsoft.net (v4.0, 2.0, 3.5, 4.5), the more PC specifications it requires.

However, applications developed on this platform are more performance sensitive. That is, if you use old computer, then you won’t install programs for Windows 8 on it, which means you don’t need platform version 4.5.

For microsoft installations.net framework any version (v4.0, 2.0, 3.5, 4.5) you will need:

• operating system of the Windows family, starting with XP sp3 or server 2003 Sp2;
• computer with a processor of 1 GHz;
• no less than 512 MB RAM;
• any version of processor architecture starting from x86.

Software installation process

You need to take this fact into account: for installation you will need two programs, usually built into the operating system. If you are using XP without updates, then you need to download them from the official Microsoft website. Minimum versions you will need:

• Windows Installer 3.1;
• Browser fifth Internet versions Explorer.

You can find out which version you have installed by viewing all components. But before you start the installation, it is advisable to update all system software. In order to do this, fulfill the following conditions:

1. Open control panel;
2. Find “Windows Update”;
3. Check for important updates and install them.

You can download any version (v4.0, 2.0, 3.5, 4.5) of the microsoft .net framework on the official Microsoft website.

Some of the applications themselves offer installation of the version (v4.0, 2.0, 3.5, 4.5) that they need. Adding one component may include several more, depending on the needs of the software, as well as the platform itself (for example, 3.0 and 2.0 are installed together with the 3.5 platform).

The installation itself is very simple and intuitive. If a failure occurs during the installation of a component, or the system displays an error message, you need to disable or remove all versions (v4.0, 2.0, 3.5, 4.5) microsoft.net

Removing and disabling the Framework

Why remove the framework? If you have a problem after updating one of the windows components, you can do the following:

1. Try disabling the last installed element;
2. Delete it standard means;
3. Use the special net framework cleanup tool.

Restoring work using standard Windows tools

To disable a component, go to “Control Panel”, “Turn components on or off”. Find the version (v4.0, 2.0, 3.5, 4.5) that was installed last and uncheck (deactivate), then click the “OK” button.

If the problem did not occur during installation, but during starting windows, then most likely there was a failure in the system. If the error is critical and prevents you from loading, then you need to solve the problem in safe mode. In order to get rid of failures, remove the framework programs through the standard “Add or Remove Programs”.

When removing, start with the maximum installed version and end with the minimum. That is, in order of priority, uninstall v4.0 – 3.5 – 3.0 – 2.0 – 1.1 After that, you need to download the versions you need from the official website.

Using additional software

Due to the numerous versions, failures can be quite varied. Established funds Windows does not always help you completely remove software, leaving behind unnecessary registry entries, settings files and system libraries.

This can cause even more serious problems later. Therefore it was created special program to remove – net framework cleanup tool.

The utility is very simple. After launching it, you need to click the “Cleanup Now” button. The net framework cleanup tool works in such a way that it completely removes all traces of the component's action, including:

• software;
• related updates;
• registry entries;
• settings files;
• system libraries.

Thanks to this program, you can remove unnecessary old components without any problems or consequences, as well as get rid of operating system errors in the event of incorrect installation or component failure.

Many people who are not very familiar with the topic have a natural question: what is it? Net Framework. In this article we will try to cover the topic in the simplest possible terms.

Microsoft .Net Framework is a so-called software platform. In general terms, we can draw an analogy with video files that will not play if the system does not have required codec. In this case, the video file is a program written using .Net technology, and the codec is the Microsoft .Net Framework itself. Moreover, for an application written on a specific version of the framework to work, it is necessary to install this particular version.

This was done so that the developer could abstract as much as possible from the system environment on the user’s computer. He should not care what operating system is installed, what bit capacity the processor has - 32-bit or 64-bit, what its architecture is, etc. To start the program it is enough to this system an implementation of the .Net Framework existed and was installed. For operating systems Windows platform is being developed by its creator, Microsoft. There are also independent implementations, most notably Mono and Portable.NET, which allow you to run .Net programs on other operating systems, such as Linux.

Architecture .Net Framework

The platform consists of two parts. The basis is the Common Language Runtime (CLR), which can run both regular programs and server applications. The second, no less important part is the Framework Class Library (FCL), which contains many components for working with databases, networking, input/output, files, user interface, etc. This allows the developer not to engage in low-level programming, but to use ready-made classes.

Important Parts of the Class Library

Windows Forms - responsible for developing the graphical interface. In fact, it is a wrapper over the Win32 API.

ADO.NET- provides access to data. Mainly used for working with databases.

ASP.NET- technology for developing websites, web applications and web services.

Language Integrated Query (LINQ)- implementation of a query language reminiscent of SQL syntax in programs on .Net.

Windows Presentation Foundation (WPF)- creation system graphical interfaces, which uses the XAML markup language. Unlike Windows Forms, it uses DirectX graphics technology, which provides more fast work due to hardware graphics acceleration.

Windows Communication Foundation (WCF)- a system for exchanging data between .Net applications. Used to create distributed applications.

Programming languages.Net

One of the main ideas inherent in .Net is compatibility various parts applications that can be developed in different languages. For example, a program written in C# can call a method from a library written in Visual Basic .NET, or a class in Managed C++ can be inherited from a class in Delphi .Net.

Languages ​​included in Visual Studio: C#, J# (most recently in Visual Studio 2005), Visual Basic .NET, JScript .NET, C++/CLI, F# (Visual Studio 2010).

There are also independent projects that allow you to develop programs for the .Net Framework in other languages.

We hope that in this material we answered the question of what the Microsoft .Net Framework is and why it is needed.

If you frequently install programs, you've probably encountered Microsoft .NET Framework errors. The two most common ones are that it is either not installed, or the wrong version is installed.

Why is this happening? What is it and why do we need the NET Framework?

What is the .NET Framework?

You probably know that the main activity of programmers is writing code. They use different programming languages ​​to tell the computer what it should do:

But there is one problem - programming languages ​​are quite primitive. With their help, you can easily perform simple operations like addition and multiplication. Everything else requires long and hard work. Do you want to display text or images on the screen? Then you will have to write a lot of code using the simplest elements of the language.

This is where the .NET Framework comes to the rescue. Essentially, it is an extensive collection of written code snippets ( created and maintained by Microsoft), which programmers can use to write programs faster.

For example, the .NET Framework takes care of all operations for rendering windows on the screen. The programmer can only insert text, think over the program menu, set the behavior of the buttons when the user clicks on them, etc.

But the .NET Framework is much more than just a bunch of extra code. It includes tools designed to reduce development time and additional APIs that programmers can use to easily interact with services such as Windows Store. Instead of manually writing all the necessary code to support a universal Windows platforms, you can use the .NET Framework:

There is only one drawback to developing applications using the .NET Framework - they cannot run if .NET is not installed on your system.

NET Framework consists of two parts. The first part includes a set of pre-written code ( officially referred to as SDK, Dev Packs or "Developer Packs"). The second part includes a program that can interpret .NET Framework code into commands for the operating system. This part, which is called " runtime", allows you to run programs written using the .NET Framework.

In this respect, the .NET Framework resembles Java - to use applications written in it, you must download the Java Runtime Environment.

In a nutshell, why do you need the Microsoft NET Framework: If you are a casual user who doesn't intend to do any programming, you only need the .NET Framework runtime.

How to install the .NET Framework

Most Windows computers already have the .NET Framework installed, but the version may be outdated. For example, Windows 8 and 8.1 come with version 4.5.1, and Windows 10 comes with version 4.6, 4.6.1, or 4.6.2.

At the time of writing, the latest version is .NET Framework 4.7. This is what we will install:

The .NET Framework can also be installed via Windows Update. But many turn it off Windows update, That's why this method would be preferable.

Before installation - .NET Framework 4.7 can be installed on Windows 10, Windows 8.1 and Windows 7 SP1 on both 32-bit and 64-bit systems. For installation to proceed without errors, Microsoft recommends having at least 2.5 GB of free space on your hard drive.

Microsoft offers two types of installers: web installer and offline installer. The web installer weighs less than 2 MB and downloads all the necessary components during installation. Therefore, you will need a stable internet connection.

The offline installer weighs about 60 MB and does not require Internet access during installation.

Both installers contain the same NET versions Framework, but we prefer to use the offline installer. It is more reliable, and will always be at hand if you need to reinstall the .NET Framework. Once downloaded, the installation process should not be difficult - just follow the instructions that appear on the screen. And then you will quickly understand why NET Framework 4 is needed.

NET Framework 4.7 Web Installer

NET Framework 4.7 Offline Installer

Please note that version 4.7 is an in-progress update to versions 4, 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1, and 4.6.2. Therefore, do not uninstall previous versions after installation. .NET Framework 3.5 SP1 and older versions are installed separately.

By default, the .NET Framework installs the English version no matter which installer you use. To localize, you need to download the appropriate language pack. For now language packs for version 4.7 are only available as standalone installers.

.NET FrameWork— This is a technology for writing software for a family of operating systems Windows systems. The main principle of .NET is universality program code, as well as the versatility of the application developed in .NET, which allows it to work on any operating system,
supporting .NET technology.

Thus, a program written in a programming language that Windows does not understand will run perfectly fine on Windows, thanks to .NET FrameWork.

A huge number of popular programs require the installation of .NET FrameWork and this is no coincidence, this mainly happens because they are made in uncommon programming languages ​​that Windows does not initially understand, but thanks to .NET, it begins to understand and even compile and run such programs.

Moreover, it is safe to say that Windows has gained such popularity mainly due to the development of .NET, which makes Windows universal and allows programs not directly designed for Windows to run on it. This is very convenient for both users and programmers, who are now freed from problems with developing for Windows.

In other words, .NET FrameWork should be on every computer, as it greatly enhances the capabilities of the Windows OS. Starting with Windows 7, Microsoft began to build .NET into the OS, which allows users not to worry about it. However, it is advisable to update this component to the final version, and today it is v4.5.

Results

To summarize, we can say that .NET FrameWork is a truly wonderful technology, thanks to which we, ordinary users, can easily run various software that is not directly intended for Windows, without worrying about all sorts of problems and conflicts. And for programmers, this is a wonderful tool that greatly facilitates their work.
