Microsoft .NET Framework Overview

Microsoft .NET Framework is a CLR-based software platform that provides conditions for the development and installation of computer software. Contains system components and libraries necessary for working with applications, provides interaction with data located on local drives and on the web. The platform is adapted for the Windows environment, starting from version 7 is integral part OS.

Platform functionality

Microsoft .NET Framework ensures the functioning of most modern programs, allows you to work in Windows environment with applications created for other operating systems. It has an extensive database of components and functions to perform various actions, works with any type of data, provides the universality of program elements and their suitability for use with any application.

Platform features include:

  • memory management;
  • creating conditions for launching applications;
  • adaptation for Windows of third-party software;
  • Russian language support;
  • ensuring compatibility between programming languages.

The Microsoft .NET Framework facilitates the software development process, eliminates technical conflicts when installing and running programs on any hardware that runs under Windows control. It is possible to extend the platform to other operating systems. There are two installation options: using the web or offline installer. In the first case necessary components and language packs are downloaded via the Internet, in the second one, the pre-downloaded distribution is launched and unpacked, followed by the addition of language packs.

Features of version 4.7

The version of Microsoft .NET Framework 4.7, released in April 2017, is adapted for Windows 10 v1703, it has been improved, new functionality.

Among the changes made:

  • improvements in CLR and BCL;
  • support improvement multi-core processors;
  • background garbage collection;
  • attaching a server profiler;
  • adding new file types;
  • easier debugging;
  • simplification of data access.

October 2017 saw the release of an updated version of Microsoft .NET Framework 4.7.1 for Windows 10 and Server 2016 versions with Service Pack 1709 installed, performance improvements, and better interaction with language environments.

".NET Framework" is a special software platform with which it is written great amount applications for the Windows operating system. These programs require the .NET Framework environment to be installed on your computer.

On this page you can download for free desired version.NET Framework installer. Also, you can learn about the purpose of the .NET Framework, system requirements and read the instructions for installing or fixing errors associated with its operation on various versions of Windows.

Introduction. Why you need .Net Framework

What is .Net Framework? Microsoft .Net Framework- a distributed software platform that is used to develop modern software. Architecture .net":

  • Allows developers not to waste time on working out the interaction of the created product with the environment in which it will be executed (whether it be hardware characteristics, compatibility, OS features or other technical aspects of the environment).
All the nuances to create a comfortable working environment for an application or software takes over the .Net Framework
  • Able to work with many programming languages ​​using a set of special algorithms, which gives application developers the opportunity to use almost any known construction principle program code for your software.
In other words, .net framework becomes the basis for running applications on various operating systems, giving end users the ability to use any application that is compatible with this component, regardless of the characteristics of the computer or any other device.

System Requirements for Optimal Operation of .Net Framework

Hardware requirements for normal operation .net framework low enough, so the component will work even on the most weak computer. The rest of the information in this chapter is intended primarily for novice users.
More advanced ones can skip to the chapter where you will learn about . Your computer requires:

  • Processor frequency 1 GHz and higher;
  • Volume random access memory at least 512 MB;
  • The minimum amount of hard disk space in the size 4.5 GB.
The .Net Framework has quite a few versions that have been released since the days of Windows XP, but there have been no major changes in the architecture of the component. Please note that the package version .net framework, on which this or that program was developed will require relevant(2, 3, 4 ) version on your computer.
Therefore, for better compatibility with the maximum number applications must have all possible variations of this component installed. But this does not mean that the latest libraries will be fully supported by older operating systems.
Sometimes, in order to install the appropriate version of the .Net Framework, you need to upgrade to a new one Windows versions.
We strongly recommend that users install Windows 10.

Determining the bitness of the operating system: x32 (x86) or x64

Bit depth his operating system(if necessary) you can look at "Properties" computer.
Figure 1. Find out the bit depth of the system.
This information will be required when installing older versions .net framework.
The new libraries are suitable for OS of both bit depths (x32-x64).

Latest version of .Net Framework available for installation on your OS

Last .net framework, which can be installed on all these operating systems (excluding Windows XP) manually - this is version 4.7. Before installing a component on a computer, make sure that the version you need is not integrated into the OS default by reading the following information:

  • Windows XP. Integrated version - 1.0SP2;
  • Windows Integrated versions - 2.0SP2, 3.0SP2 and 3.5SP1;
  • Windows 8 or 8.1. Integrated versions - 4.5 and 4.5.1 respectively for these OS;
  • Windows Integrated version - 4.6 or 4.6.1 depending on the installed updates.
note!

Latest versions of .Net Framework do not contain all those libraries that were previously in older versions of the .NET Framework.
This means that in order to run some old programs or games, you will have to install the old (!) Versions of the .NET Framework necessary for their operation.

You also need to remember: the pre-installed libraries cannot be removed by the standard means of the operating system itself.

How to install the right version of .Net Framework

Let's say you need an older version of a component to run a particular application.
Usually software itself notifies the user about the absence of the required version on the OS .net framework, displaying the corresponding error window. An example of such a message is shown in the figure below:


Figure 2. An example of a message about the absence of the required version of the .Net Framework.
In this case, you just need to download the required version of the component for your OS (of course, observing the bit depth) using a special installer which is of two types:

  1. Online (web) the installer downloads all the necessary files .net framework from Microsoft servers and independently unpacks the downloaded data. Requires an internet connection.
  2. Standalone (full) the installer already contains all the libraries that are needed for a full installation .net framework without internet connection.
There are no other fundamental differences. When using the standalone version of the component, installation errors occur somewhat less often, so when searching for links, they will most often lead to it. To quickly jump to the download of the desired version, go back and click on the heading with the name of the component you need.

Error installing .Net Framework 3.5: 0x800F0906, 0x800F081F, 0x800F0907 on Windows 8 or 8.1

This problem occurs when you try to install .Net Framework 3.5.Before performing the steps described below, it is recommended that you read the chapter: . Errors 0x800F0906, 0x800F081F, 0x800F0907 in most cases, they appear when installing the .NET Framework 3.5, when security updates are installed in the operating system KB2966826 and KB2966828.

This is most likely due to the fact that some windows updates may not be tested to work or interact with the .NET Framework 3.5 installer.

MS developers proceeded from the fact that users will use new, more current versions The framework, and the .NET Framework 3.5 installer itself, was created long before these updates, and does not take into account the changes in policies and security mechanisms that they bring.

To use the .Net Framework 3.5 (and below) on newer operating systems, you must:

  1. Temporarily disable "Windows Update";
  2. Delete KB2966826 and KB2966828 through standard remedy"The installing and deleting of programms";
  3. Restart your computer, repeat the installation .net framework.
After installing the component, you can turn it back on automatic updates.

Selecting a hard drive and folder for unpacking .NET before installation (the installer can choose the drive itself, for example drive A:)

The installer for the latest versions of the .NET Framework chooses the destination drive and folder of its choice. This may be a rather non-obvious choice, such as drive A:, or another drive not designed for these tasks.
To get around this problem, just run the installation using command line(see figure 5): Figure 5. Installing the .NET Framework 4.7.1 with unpacking to a specific folder.
