".NET Framework" is a special software platform with which a huge number of applications for the Windows operating system are written. These programs require the .NET Framework environment to be installed on your computer.
On this page, you can download the required version of the .NET Framework installer for free. 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 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).
- Able to work with many programming languages using a set of special algorithms, which gives application developers the opportunity to use almost any known principle of constructing program code for their software.
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 weakest 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;
- The amount of RAM is not less than 512 MB;
- The minimum amount of hard disk space in the size 4.5 GB.
Therefore, for best compatibility with the maximum number of applications, all possible variations of this component should be 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 your operating system (if necessary) you can look in "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.
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:
- Online (web) installer downloads everything necessary files .net framework from Microsoft servers and independently unpacks the downloaded data. Requires an internet connection.
- Standalone (full) the installer already contains all the libraries that are needed for a full installation .net framework without internet connection.
Download .Net Framework 4.7 (including versions: 4.6.2, 4.6.1, 4.6, 4.5.2 and 4)
Currently (October, 2017) version .Net Framework 4.7 is the last one. Download this component in full delivers from having to download the following versions:
- .Net Framework 4.6 (4.6.1 and 4.6.2 );
- .Net Framework 4.5 (4.5.1 and 4.5.2 );
- .Net Framework 4.
Version 4.7 supported by the following operating systems of any bitness (x32-x64):
- Windows 10 Creators Update (integrated);
- Windows 10 Anniversary Update;
- Windows 8 or 8.1;
- Windows 7;
- Windows Server 2016, 2012 and 2008.
Download .Net Framework 3.5 (including versions: 3.0 and 2.0)
You can find more information and download .Net Framework 3.5 on the Microsoft website or download the library in one file from our website using the links provided.
NET Framework is evolving and newer versions may not have some features that were previously present in earlier versions.
This happens for various reasons: some components could become outdated, become irrelevant, or they could be replaced by new, more advanced components of the Framework. Some older applications may need exactly those old components that are missing in newer versions, which requires the installation of one of the older versions of MS .NET Framework. Version 3.5 already includes minor versions of libraries (so you don't need to download them separately):
This component is compatible with any currently used operating system from Microsoft, including Windows XP.
Installation .Net Framework 3.5 in most cases, it will allow you to launch and ensure the normal operation of any old program or game. However, if you are experiencing problems with this version of the component, please review the information in the next chapter.
Errors when installing or running the .Net Framework
Sometimes incorrect installation or update .net framework may cause the component to malfunction. This chapter provides information on various errors that you may encounter at different stages of using libraries.

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:
- Temporarily disable "Windows Update";
- Delete KB2966826 and KB2966828 through standard remedy"The installing and deleting of programms";
- Restart your computer, repeat the installation .net framework.
Selecting a hard disk and folder for unpacking .NET before installation (the installer can choose the disk 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 the command line (see Figure 5): Figure 5. Installing the .NET Framework 4.7.1 with unpacking to a specific folder.
NET Framework (Dot Net Framework) is a software platform (software framework) developed by Microsoft in 2002, mainly for the Microsoft Windows operating system. Includes extensive libraries and also provides cross-compatibility (each language can use code written in other languages) of multiple programming languages. Programs written in the .NET Framework run in a software environment (as opposed to hardware) known as the Common Language Runtime (CLR), which is a virtual machine that provides security, memory allocation, and exception handling. The class library and the CLR together make up the .NET Framework.
The .NET Framework Core Class Library gives you access to user interface, data exchange, database connectivity, cryptography, web application development, computational algorithms and network connections. Programmers create their applications by linking their own code with .NET Framework libraries as well as other libraries. The .NET Framework is intended to be used by most new applications that are developed.

The Microsoft .NET Framework 4 is a software component which can be added to the Microsoft Windows operating system.
It provides a large body of pre-coded solutions to common program requirements, and manages the execution of programs written specifically for the framework.
The Microsoft .NET Framework 4 focuses on the core pillars of developer experience, support for the latest platforms, targeted experiences for specific application types, and core architecture improvements.
The Microsoft .NET Framework 4 is a key Microsoft offering, and is intended to be used by most new applications created for the Windows platform.
The pre-coded solutions in the namespaces form the framework’s class library and cover a large range of programming needs in areas including the user interface, data access, cryptography, web application development, numeric algorithms, and network communications. The functions of the class library are used by programmers who combine them with their own code to produce applications.
Programs written for the .NET Framework execute in a software environment that manages the program's runtime requirements. This runtime environment, which is also a part of the .NET Framework, is known as the Common Language Runtime (CLR).
The CLR provides the appearance of an application virtual machine, so that programmers need not consider the capabilities of the specific CPU that will execute the program. The CLR also provides other important services such as security mechanisms, memory management, and exception handling.
The class library and the CLR together compose the .NET Framework. The framework is intended to make it easier to develop computer applications and to reduce the vulnerability of applications and computers to security threats.
Microsoft .NET Framework 4 new features and improvements:
- Improvements in Common Language Runtime (CLR) and Base Class Library (BCL)
- Performance improvement including better multicore support, background garbage collection, and profiler attach on server.
- New memory mapped file and numeric types.
- Easier debugging including dump debugging, Watson minidumps, mixed mode debugging for 64 bit and code contracts.
- For a comprehensive list of enhancements to CLR and BCL go here.
- Innovations in the Visual Basic and C# languages, for example statement lambdas, implicit line continuations, dynamic dispatch, and named/optional parameters.
- Improvements in Data Access and Modeling
- The Entity Framework enables developers to program against relational databases using .NET objects and Language Integrated Query (LINQ). It has many new features, including persistence ignorance and POCO support, foreign key associations, lazy loading, test-driven development support, functions in the model, and new LINQ operators. Additional features include better n-tier support with self-tracking entities, customizable code generation using T4 templates, model first development, an improved designer experience, better performance, and pluralization of entity sets.
- WCF Data Services is a component of the .NET Framework that enables you to create REST-based services and applications that use the Open Data Protocol (OData) to expose and consume data over the Web. WCF Data Services has many new features, including enhanced BLOB support, data binding, row count, feed customization, projections, and request pipeline improvements. Built-in integration with Microsoft office 2010 now makes it possible to expose Microsoft Office SharePoint Server data as an OData feed and access that data feed by using the WCF Data Services client library.
- Enhancements to ASP.NET
- More control over HTML, element IDs and custom CSS that make it much easier to create standards-compliant and SEO-friendly web forms.
- New dynamic data features including new query filters, entity templates, richer support for Entity Framework 4, and validation and templating features that can be easily applied to existing web forms.
- Web forms support for new AJAX library improvements including built-in support for content delivery networks (CDNs).
- Improvements in Windows Presentation Foundation (WPF)
- Added support for Windows 7 multi-touch, ribbon controls, and taskbar extensibility features.
- Added support for Surface 2.0 SDK.
- New line-of-business controls including charting control, smart edit, data grid, and others that improve the experience for developers who build data centric applications.
- Improvements in performance and scalability.
- Visual improvements in text clarity, layout pixel snapping, localization, and interoperability.
- Improvements to Windows Workflow (WF) that enable developers to better host and interact with workflows. These include an improved activity programming model, an improved designer experience, a new flowchart modeling style, an expanded activity palette, workflow-rules integration, and new message correlation features. The .NET Framework 4 also offers significant performance gains for WF-based workflows.
- Improvements to Windows Communication Foundation (WCF) such as support for WCF Workflow Services enabling workflow programs with messaging activities, correlation support. Additionally, .NET Framework 4 provides new WCF features such as service discovery, routing service, REST support, diagnostics, and performance.

Microsoft development framework
NET is a platform for developing and managing applications. It comes with a variety of coding tools, and libraries that allow you to create complex commands. There are many different implementations of .NET, including Windows, Linux, and iOS. They all originate from .NET framework, which supports services like website maintenance and desktop apps.
software development
For Windows users, .NET framework is a package that comes installed in your device This version, 4.8, comes with Windows 7 SP1. The updates come on a scheduled basis, and it usually installs upon Windows update. As a developer, you always need to have the latest version of .NET. Once upgraded to a later version, previous patches of .NET framework will not install. In order to run applications created by this platform, you would need to use .NET. The versions needed to run certain programs normally are not reliant on a specific patch, but the updates might interfere with the mechanics of your applications.
NET framework has a lot to offer. Some of the addons will help you much more on specific tasks. Check out the developer pack once you've downloaded the latest version - it allows access from Visual Studio. You may need to use installation scripts to get the exact packages you need. Keep in mind that the latest patch will always override the current one. If your applications need certain aspects of the previous .NET composition, be sure to do selective updates.
On top of increased flexibility and impactful debugging components, the latest version of .NET offers a few new features as well. You'll be looking at Base Classes, Windows Communication Foundation (WCF), Windows Presentation Foundation (WPF), and Common Language runtime.
Improved accessibility
In the new, stable version 4.8, .NET framework addresses critical issues that were common in the previous patches. One of them is the Cryptographic Exception being thrown in production systems. This is due to not many developers running their machines in FIPS (Federal Information Processing Standards) mode. Before, cryptographic providers who have not undergone FIPS configurations would get thrown off. That's no longer the case in the updated .NET.
The patches come with improvements on the Zlib external compression library under the Base Class Library (BCL). When you're using X509Certificate2, the occurrence of object finalizations have been reduced. This applies to all related types of codes.
New commands such as ServiceHealthBehavior are being introduced through the WCF. Health endpoints are used to monitor the health status of certain services. The new WCF behavior allows users to receive service health status in HTTP codes. It can also publish useful information about a service, including current state, throttle counts, and capacity. You would need to learn the code lines for the new commands to execute the behavior.
Other enhancements include accessibility in Windows Forms. Changes have been made so that application data is communicated better for the visually impaired. These are not core adjustments to the systems, so they don't affect regular users.
Bug fixes touched up on ASP.Net multivalue HTTP headers handling and memory leaks affecting HttpWebRequest and WPF. Hashing algorithms for tasks such as XOML file checksums generator and internal memory calculations have also been modified. This change has been set to default, so if you wish to use the old algorithms, you'd need to revert it manually.
High DPI enhancements
Some features come with Windows Presentation Foundation (WPF), such as high DPI (Dots Per Inch) enhancement. This is useful if you want to update an application to handle display changes at a higher scale. It will allow the app to maintain a crisp display on any platform. Applications that use older programming software such as Windows Forms or Win32 cannot adapt to DPI scaling without extra coding. This results in blurry and low quality render. The DPI enhancements eliminate such problems.
Another feature included in WPF is added support for hosted HWND(Handle to a Window) and Windows Form inter-operation in high DPI apps. These have to be run on platforms that support Mix Mode DPI scaling. If you have Windows 10, the updates for this should have already been installed. Apps that run in these platforms and their components are now scaled and sized appropriately
You'll also notice minor changes in display like the Window Forms labels. These labels will be automatically rendered in high contrast when HC mode is enabled. ComboBox controls theme issues have also been fixed while in high-contrast mode.
common language runtime
The runtime in .NET framework has been improved in many aspects. Though there were no critical problems with the previous versions, a lot of QoL changes have been delivered. Persistent bugs of the JIT compiler have been fixed. The new JIT (Just in Time) compiler in this .NET framework version is based on that of the .NET Core 2.1. Other components have also been optimized.
NGEN (Native Image Generator) memory management issues have also been improved. Data received from NGEN images are no longer prone to memory modifications. You will also notice additional power in scanning. This will now scan for all assemblies. In earlier versions, if you were using , the runtime will scan all files loaded by it. The exception is that if these assemblies were loaded from other sources, they would not get scanned. That could result in undetected spyware. This issue has been addressed in the latest version of .NET.
Flexibility
NET framework is one of the most versatile and popular platforms in today's development industry. Coding may not be for everyone, and .NET is definitely not beginner-friendly. But, the platform comes with many solutions for it. You can start by using .NET standard or .NET Core, which is an open-source program. The problem with .NET framework is that the updates generally take a long time to optimize. Plus, if you're developing an application on one specific version, new releases may interfere with the current progress. It's also difficult to maintain or install an older version if .NET has already been updated.
