• Today, we are releasing the July 2020 Security and Quality Rollup Updates for.NET Framework. Security CVE-2020-1147–.NET Framework Remote Code Execution Vulnerability. A remote code execution vulnerability exists in.NET Framework, Microsoft SharePoint, and Visual Studio when the software fails to check the source markup of XML file input.
• .NET Framework (pronounced as 'dot net') is a software framework developed by Microsoft that runs primarily on Microsoft Windows.It includes a large class library called Framework Class Library (FCL) and provides language interoperability (each language can use code written in other languages) across several programming languages.

.NET Framework FAQ

What is .NET Framework used for?

.NET Framework is used to create and run software applications. .NET apps can run on many operating systems, using different implementations of .NET. .NET Framework is used for running .NET apps on Windows.

Who uses .NET Framework?

Software developers and the users of their applications both use .NET Framework:

• Users of applications built with the .NET Framework need to have .NET Framework installed. In most cases, .NET Framework is already installed with Windows. If needed, you can download .NET Framework.
• Software developers use .NET Framework to build many different types of applications—websites, services, desktop apps, and more with Visual Studio. Visual Studio is an integrated development environment (IDE) that provides development productivity tools and debugging capabilities. See the .NET customer showcase for examples of what people are building with .NET.

Microsoft Net Framework Update

Why do I need .NET Framework?

You need .NET Framework installed in order to run applications on Windows that were created using .NET Framework. It is already included in many versions of Windows. You only need to download and install .NET Framework if prompted to do so.

How does .NET Framework work?

.NET Framework applications are written in C#, F#, or Visual Basic and compiled to Common Intermediate Language (CIL). The Common Language Runtime (CLR) runs .NET applications on a given machine, converting the CIL to machine code. See Architecture of .NET Framework for more info.

What are the main components/features of .NET Framework?

The two major components of .NET Framework are the Common Language Runtime (CLR) and the .NET Framework Class Library. The CLR is the execution engine that handles running applications. The Class Library provides a set of APIs and types for common functionality. See Architecture of .NET Framework for more info.

What is the difference between .NET Core and .NET Framework?

.NET Core and .NET Framework share many of the same components and you can share code across the two. Some key differences include:

• .NET Core is cross-platform and runs on Linux, macOS, and Windows. .NET Framework only runs on Windows.
• .NET Core is open-source and accepts contributions from the community. The .NET Framework source code is available, but does not take direct contributions.
• The majority of .NET innovation happens in .NET Core.
• .NET Framework is included in Windows and automatically updated machine-wide by Windows Update. .NET Core is shipped independently.

See Choosing between .NET Core and .NET Framework for more details.

Can you have multiple .NET Frameworks installed?

Some versions of .NET Framework are installed side-by-side, while others will upgrade an existing version (known as an in-place update). In-place updates occur when two .NET Framework versions share the same CLR version.

For example, installing .NET Framework 4.8 on a machine with .NET Framework 4.7.2 and 3.5 installed will perform an in-place update of the 4.7.2 installation and leave 3.5 installed separately.

How much does .NET Framework cost?

.NET Framework is free, like the rest of the .NET platform. There are no fees or licensing costs, including for commercial use. See .NET is free for more details.

Which version of .NET Framework should I use?

In most cases, you should use the latest stable release. Currently, that's .NET Framework 4.8 .

Applications that were created with any 4.x version of .NET Framework will run on .NET Framework 4.8 . To run an application that was created for an earlier version (for example, .NET Framework 3.5), you should install that version. See Download .NET Framework for a complete list.

What is the support policy for .NET Framework?

.NET Framework 4.8 is the latest version of .NET Framework and will continue to be distributed with future releases of Windows. As long as it is installed on a supported version of Windows, .NET Framework 4.8 will continue to also be supported.
