Net framework 3.5 what a program. Install or update, fix bugs. The latest version of the .Net Framework available for installation on your OS

Which user has never had an offensive situation: you are looking for the necessary information, follow the link to a very promising site and OOPS! it is blocked in your country for some reason. Unpleasant, but completely solvable. On the network you can find many programs that hide your IP address, thereby deceiving the tracking programs and letting them go to inaccessible sites.

The Browsec VPN browser extension is ideal for these purposes. After installing it, you can start data encryption at any time. And you're done: all traffic will be forwarded through a secure cloud network. As a result, it will be impossible to analyze your actions (and understand that it is you).

This method works both globally (for example, it opens access to sites prohibited in the country), and more narrowly, in particular, in the corporate network. It is not a secret for anybody that often the bosses set before the system administrators the task of blocking social networks and all kinds of "entertainment" sites on work computers. After installing Browsec VPN, this chaos no longer concerns you. Unless, of course, the boss sneaks up from behind and finds a blocked portal.

Key features

Browsec VPN, being a browser extension rather than a standalone program, requires far fewer resources while performing its functions perfectly. As soon as you click on its icon (appears to the right of the address bar), and it will start working. Your IP address will change to a foreign one, and now you can work with the sites you need in complete confidence in your security. All you need is to download Browsec VPN for free.

Browsec VPN bypasses both corporate network restrictions and regional bans. In addition, the extension solves the issue of data confidentiality. No one will be able to track the sites that you visit while the VPN is turned on. After all, according to the data, it was not you at all.

Pros and cons of extension

  • Requires little space and network resources.
  • Helps to bypass the ban on visiting certain resources.

".Net Framework" is a special software platform with which a huge number of applications are written for the Windows operating system. For such programs to work, the .NET Framework environment must be installed on your computer.

On this page, you can download the required version of the .NET Framework installer for free. Also, you can find out about the purpose of the .NET Framework, system requirements and familiarize yourself with the instructions for installing or fixing errors related to its operation on different 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).
All the nuances of creating a comfortable working environment for an application or software are taken care of by the .Net Framework
  • He is able to work with many programming languages ​​using a set of special algorithms, which gives application creators the opportunity to use almost any known principle of constructing program code for their software.
In other words, .Net Framework becomes the basis for running applications on various operating systems, providing end users with the ability to use any applications compatible with this component, regardless of the characteristics of a computer or any other device.

System requirements for optimal performance of the .Net Framework

Hardware requirements for normal operation .Net Framework low enough that the component will work even on the weakest computer. The rest of the information in this chapter is primarily intended for novice users.
The more advanced can move on to the chapter in which you will learn about.
Your computer requires:

  • Processor with frequency 1 GHZ and higher;
  • The amount of RAM is not less than 512 MB;
  • Minimum amount of hard disk space in size 4.5 GB.
The .Net Framework has a lot of versions that have been released since the days of Windows XP, but there have been no major changes in the architecture of the component. Remember the package version .Net Framework, on which this or that program was developed will require the corresponding(2, 3, 4 ) version on your computer.
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 correct version of the .Net Framework, you need to upgrade to a newer version of Windows.
We highly recommend users to 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 capacity of the system.
This information will be required when installing older versions. .Net Framework.
The new libraries are suitable for both OS (x32-x64).

The latest version of the .Net Framework available for installation on your OS

Last .Net Framework which can be installed on all these OS (except Windows XP) manually, - this is version 4.7. Before installing a component on your computer, make sure that the version you need is not integrated into the OS default after reviewing the following information:

  • Windows XP. Integrated version - 1.0 SP2;
  • Windows Integrated Versions - 2.0 SP2, 3.0 SP2 and 3.5 SP1;
  • 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!

Newest Versions of the .Net Framework do not contain all those libraries that were previously in the old version 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 them to work.

It is also necessary to remember: preinstalled libraries cannot be removed by standard means of the operating system itself.

How to install the correct version of the .Net Framework

Let's say you need an older version of a component to run a specific application.
Usually the software itself notifies the user about the absence of the required version on the OS. .Net Framework by 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 lack of the required version of the .Net Framework.
In this case, you just need to load 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 complete installation .Net Framework without internet connection.
There are no other fundamental differences. When using the stand-alone version of the component, installation errors occur somewhat less often, therefore, when searching, links will most often lead to it. To quickly jump to the download of the required version, go back and click on the title with the name of the component you need.

Download .Net Framework 4.7 (including versions: 4.6.2, 4.6.1, 4.6, 4.5.2 and 4)

At the moment (October, 2017) version .Net Framework 4.7 is the last one. Downloading this component completely relieves from the need 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.
You can download the .Net Framework 4.7 from our website using a direct link or from the page on the official Microsoft website dedicated to version 4.7 of the component, where you can also find additional information (system requirements, restrictions, etc.)
Version 4.7 supported by the following OS 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.
If a component does not install or does not work properly, read the chapter:.

Download .Net Framework 3.5 (including versions: 3.0 and 2.0)



You can read 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 be missing 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 the MS .NET Framework. Version 3.5 already includes minor versions of the libraries (so you don't need to download them separately):

  • .Net Framework 2.0;
  • .Net Framework 3.0.
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 any old program or game to start and ensure normal operation. However, if you are experiencing problems with this version of the component, see the information in the next chapter.

Errors while installing or running .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 the libraries. ".Net".First you need to download the official utility from Microsoft called .Net Framework Repair Tool», Which will automatically help to solve the problem with the component. You will find instructions for this program below.

.NET Framework Repair Tool will find and fix most crashes

According to the Microsoft website, this utility solves problems when working and installing or updating any version .Net Framework.

Microsoft .Net Framework Repair Tool (online version). | 1.22 MB The utility is designed to identify the most common problems when working or installing the .NET Framework, as well as to automatically fix them.

Now all that remains is to restart the computer and reinstall the installation .Net Framework.

.Net Framework 3.5 installation error: 0x800F0906, 0x800F081F, 0x800F0907 on Windows 8 or 8.1

This issue occurs when trying to install .Net Framework 3.5.Before proceeding with the steps described below, it is recommended that you read the chapter:. Errors 0x800F0906, 0x800F081F, 0x800F0907 in most cases, they appear during the installation of the .NET Framework 3.5, when security updates are installed on 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.

The MS developers assumed that users will use new, more current versions of 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 the policies and security mechanisms that they carry.

To use .Net Framework 3.5 (and below) on new OS, you need:

  1. Temporarily disable Windows Update;
  2. Delete KB2966826 and KB2966828 through the standard Add or Remove Programs tool;
  3. Restart the computer, repeat the installation .Net Framework.
After installing the component, you can turn automatic updates back on.

Select hard drive and folder to unpack .NET before installation (installer can select drive by itself, like drive A :)

The installer of the latest versions of the .NET Framework selects the drive and destination folder as it sees fit. This may be a rather obscure choice, such as the A: drive, or another drive that is not designed for these tasks.
To work around this problem, just start the installation using the command line (see Figure 5): Figure 5. Installing .NET Framework 4.7.1 with unpacking to a specific folder.

Microsoft .NET Framework 3.5 SP 1 is a set of libraries and system components that are required for the operation of applications based on the .NET Framework architecture. This package is a cumulative update that contains many new features based on the .NET Framework 2.0, .NET Framework 3.0, .NET Framework 3.5, and includes cumulative service updates for the .NET Framework 2.0 and .NET Framework 3.0 subcomponents.

Microsoft .NET Framework 3.5 SP1 contains the following new features and enhancements:

- ASP.NET dynamic data, which provides a rich scaffolding platform to enable data-driven development without writing code. They also contain a new addition to ASP.NET AJAX that provides support for managing browser history (back button support).

- Basic improvements to the common language runtime (CLR), including: improved layout of images in native codes of the .NET Framework; no strict name checking for fully trusted assemblies; improved performance when launching applications; improved coding to reduce the execution time of finished applications; and the ability to execute managed code in ASLR mode (injecting randomness into the address space structure), if supported by the operating system. In addition, managed applications opened from network folders behave like native applications by running in full trust.

- WPF (Windows Presentation Foundation) performance improvements, including faster startup times and improved performance for bitmap effects. Additional WPF features include improved support for line-of-business applications, support for native splash screens, support for texture builders, and a new WebBrowser control.

- Publishers of ClickOnce applications can opt out of signing and hashing applications if this option is better suited to their scenarios. Developers can programmatically install ClickOnce applications that display custom branding information. ClickOnce error dialog boxes maintain links to application-specific support sites on the Internet.

- Entity Framework - an evolution of the existing set of ADO.NET data access technologies. The Entity Framework allows developers to program relational database operations according to application-specific domain models rather than underlying database models. The Entity Framework introduces some additional functionality, including support for new SQL Server 2008 types, default Entity graph serialization, and entity data source. This version of Entity Framework supports the new streaming capabilities of SQL Server 2008 for dates and files. Working with graph serialization makes it easier for developers to build Windows Communication Foundation (WCF) services that use full graph modeling as data contracts. The Entity Data Source allows web application developers who want to work with the Entity Framework to use the traditional ASP.NET data source methods.

- LINQ to SQL supports the new streaming capabilities of SQL Server 2008 for dates and files.

- The ADO.NET Data Services Platform consists of a combination of templates and libraries to expose data as a flexible RESTful data service that can be consumed by web clients on corporate networks or on the Internet. The ADO.NET Data Services Platform allows you to create data services from any data source. The conceptual view model of the underlying storage schema can be easily made available through rich integration with ADO.NET Entity Framework. Services built using the ADO.NET Data Services Platform and Windows Live Compatible Services (dev.live.com) are easily accessible from any platform. For client applications that run on Microsoft platforms, a set of client libraries is available to help you more easily interact with data services. For example, clients based on the .NET Framework can use LINQ to query data services and a simple .NET Framework object layer to update data in a service.

- Windows Communication Foundation now makes it easier to use the DataContract serializer with improved interoperability support. It enhances debugging in partial-trust scenarios and extends support for the RSS protocol so that it can be used more widely in Web 2.0 applications.

- The .NET Framework Data Provider for SQL Server (SqlClient) adds support for the file stream and sparse column functionality in SQL Server 2008.

Surely many have heard of the Microsoft .NET libraries, which are often the main source of various applications. The interaction between the software that uses it and the libraries themselves is carried out through the .NET Framework system components. Without them, many applications simply won't install.

The current versions of the .NET Framework are considered 4.6 and 4.7 , which also include the old edition 4.5 ... They are built into Windows 10, and you shouldn't have any problems installing or using them. The situation is different with the already outdated version. 3.5 ... It was widely used in the days of Windows 7 and is incompatible with the .NET Framework 4.x. Since edition 3.5 is not included with Windows 10 by default, many older programs simply won't install.

How to download and install the .NET Framework 3.5 on Windows 10

The developers have provided an option to install the old version of the .NET Framework in the Windows 10 Component Service. To download the library, you will need an Internet connection.

How to download the .NET Framework 3.5 installer for Windows 10

If for some reason you are unable to use the Windows Components Service, you have the option to download and run the .NET Framework 3.5 online installer.


How to install .NET Framework 3.5 without internet (offline)

Occasionally there are problems when using the Windows Update Web Service and users are unable to install the .NET Framework 3.5 in the two ways described above. In this case, you can use a bootable USB drive with a Windows 10 image to manually install the component (without the need for an Internet connection).


Therefore, the .NET Framework 3.5 can be installed without using an Internet connection or Windows Update.
