NET Framework is a programming model created by Microsoft in order to create software With good quality, with an attractive interface and sufficient security. This is an integral part of some applications, which has functionality for launching them.

The main idea of ​​this platform is compatibility various programs which were written in different programming languages. And also, what was written for netframe can be used in other environments besides Windows.

Microsoft NET Framework consists of 2 parts:

1. The performer's environment.
The multilingual Common Language Runtime (CLR) is the core of the platform and the main component of the system that manages the execution of user programs.

2.The Framework Class Library (FCL) which gives programs access to the runtime environment. It has a lot of elements for managing networks, databases, files, and interfaces. Developers need all this for programming.

Many users are interested in how to download NET Framework versions 3.5 for Windows 10 and why they can’t do it. And as usual, it’s worth paying attention to the computer requirements than latest version framework, the greater the characteristics it needs.

NET Framework 3.5 includes new builds to enhance the capabilities of earlier NET platforms. It also has Service Pack 1 (SP1), which updates assemblies located in the platform itself.

In principle, all versions can be installed regardless of those that came out later, and each version automatically adds early versions, if you haven't installed them yet. You can also see in version 3.5 the Client Profile installation package, which includes assemblies of the used client applications.

Windows 2000 does not work with the 3.5 framework and with a standalone installation.

Additional features in .NET Framework version 3.5:

• Using Windows Communication Foundation (WCF) technology, support for applications on portable devices has been expanded.
• Adding language tools (LINQ, new APIs)
• Added new compilers for C#, Visual Basic, C++ and J#;
• Improve debugging with diagnostic tools
• You can now add graphics to controls
• ClearType font support
• It is now possible to change the BackColor property of read-only controls
• Maintaining SelectionStart and SelectionLength properties
• And much more

How to install NET Framework

If you are running Windows, then you most likely already have some version of the NET Framework installed. But not version 3.5, it is not installed automatically and you need to download it yourself.

This can be done in two ways:

1. Download installation file, which will download files from the Internet for installation. Moreover, its weight will be only 2.8 MB. And the file size depends on your OS.
2. If there is no possibility for online installation, then try downloading the full package, its weight is decent, about 200 MB, but you can install it offline.

NET Framework (Dot Net Framework) - software platform(software framework) developed by Microsoft Corporation in 2002, mainly for operating Microsoft systems Windows. Includes extensive libraries, and also provides cross-compatibility (each language can use code written in other languages) of several programming languages. Programs written in the .NET Framework run in a software environment (as opposed to a hardware environment) known as the Common Language Runtime (CLR), which is a virtual machine, which provides security, memory allocation, and exception handling. The class library and CLR together make up the .NET Framework.

The .NET Framework core class library provides 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 the .NET Framework libraries as well as other libraries. The .NET Framework is intended to be used by most new applications being developed.

ATTENTION: Be sure to install the update packages in the same order in which the links to them are given!

Microsoft .NET Framework 3.5 SP 1 - a set of libraries and system components that are necessary 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 that enables 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 image layout in native .NET Framework codes; avoiding strict name checking for fully trusted assemblies; improved performance when launching applications; Improved code generation that reduces the execution time of completed applications; and the ability to execute managed code in ASLR mode (injecting randomness into the address space structure), if supported by the operating system. Besides, managed applications, open from network folders, behave exactly like native applications by running with full trust.

– WPF (Windows Presentation Foundation) performance improvements, including reduced startup time and improved performance for bitmap effects. Additional WPF features include improved support for business applications, support for native splash screens, support for texture builders, and new element WebBrowser controls.

– ClickOnce application publishers can opt out of application signing and hashing if this option better suits their scenarios. Developers can programmatically install ClickOnce applications that display custom information about trademark. Dialog boxes ClickOnce errors support links to application-specific support sites on the Internet.

– Entity Framework - development existing set ADO.NET data access technologies. Entity Framework allows developers to program relational database operations according to application-specific domain models rather than basic models databases. Entity Framework introduces some additional features, including support for new types SQL Server 2008, Default Entity Graph Serialization and Entity Data Source. This version of Entity Framework supports the new SQL Server 2008 streaming capabilities for dates and files. Working with graph serialization makes it easier for developers to build Windows Communication Foundation (WCF) services that use the modeling of complete graphs as data contracts. The Entity Data Source allows web application creators who want to work with the Entity Framework to use traditional data source techniques for ASP.NET.

– LINQ to SQL supports new SQL Server 2008 streaming capabilities for dates and files.

– The ADO.NET Data Services Framework consists of a combination of templates and libraries that allow you to expose data as a flexible, REST-based data service that can be ingested by web clients in corporate networks or on the Internet. The ADO.NET Data Services Platform allows you to create data services from any data source. The conceptual model of viewing the underlying storage schema can be easily made accessible through rich integration with the ADO.NET Entity Framework. Services built using the ADO.NET Data Services Framework and compatible services Windows Live(dev.live.com), easily accessible from any platform. For client applications running on Microsoft platforms, a set of client libraries is available that makes it easier to 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 the service.

– Windows Communication Foundation now makes the DataContract serializer easier to use with improved interoperability support. It improves debugging performance in partial-trust scenarios and expands support for the RSS protocol, allowing it to be more widely used in Web applications 2.0.

– The .NET Framework Data Provider for SQL Server (SqlClient) adds support for the ability to use file streams and sparse columns in SQL Server 2008.

Platform .Net Framework, which Microsoft began developing in the late 90s, represent the basis for launching software, without which the full operation of most games and programs is impossible. Default package .NET Framework 4.0 included in the original Windows 7 distribution, .NET Framework 4.5 comes with Windows 8 (8.1) and .NET Framework 4.6– with Windows 10. However separate installation The framework may be needed if the system does not have the required version, or a serious failure has occurred. So, .NET Framework 3.5 is not installed together with the “eight” and “ten”, but .NET Framework 4.5 is missing on Windows 7. Today I will tell you what to do if it does not install .NET Framework 3.5 / 4.0 / 4.5 , and where to download .NET Framework current versions.

How to find out which versions of the .NET Framework are installed on your computer?

First, let's find out which versions of the framework are installed on your desktop (laptop). The fastest way to do this is using the Registry Editor Regedit.exe, That's why:

• use the key combination " " to open the "Run" window, enter regedit and click on " OK";

• expand the branch sequentially HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP ;
• the names of subsections (folders) correspond installed packages .NET Framework(screenshot above).

How to Install .NET Framework 3.5 via Windows Control Panel

Installation algorithm .NET Framework 3.5 for all OS versions one:

• open " Control Panel" → find the section " Programs and components";
• click on the subsection " ";

• in the new window, check the box " .NET Framework 3.5" and click " OK" (screenshot below);
• confirm downloading files from the Center Windows updates(final screenshot).

However, to save time in Windows 7, in the search bar of the Start menu, type without quotes " enabling components", and in Windows 10 / 8 use the keyboard shortcut " Win + X" → in the window that opens, click the link " Enable or disable Windows components "etc.

Sometimes, when installing the framework, unfortunately, errors may occur with various codes, such as 0x800F081F, 0x800F0906 or 0x800F0907. The simplest solution is to manually download the package you are looking for .NET Framework and integrate into Windows.

Where to download .NET Framework 3.5, 4.0 and 4.5 for Windows 10/8/7

Let me remind you that the developer does not recommend without absolutely having to remove any versions .NET Framework installed on the computer. On the contrary, sequential installation, with a system reboot, of several versions of the described platform is quite possible.
