Microsoft .NET Framework 4.8 is a runtime execution environment that manages applications targeted at the .NET Framework. It consists of the common language runtime, which provides memory management and other system services. An extensive class library provides programmers with reusable code for many common app development tasks.
This redistributable package installs the .NET Framework runtime and associated files required to run applications developed to target the .NET Framework.
The Microsoft .NET Framework 4.8 is a highly compatible, in-place update to the Microsoft .NET Framework 4, 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, and 4.7.2. The offline package is ideal for systems without an internet connection or when the web installer cannot be used.
The .NET Framework is a managed execution environment that provides a variety of services to its running applications. It consists of two major components: the Common Language Runtime (CLR), the execution engine responsible for running applications. The .NET Framework Class Library provides a library of tested, reusable code that developers can call from their applications.
Microsoft .NET Framework provides services:
- Memory management. In many programming languages, programmers are responsible for allocating and releasing memory and for handling object lifetimes. In .NET Framework applications, the CLR provides these services on behalf of the application.
- A common type system. In traditional programming languages, basic types are defined by the compiler, which complicates cross-language interoperability. In the .NET Framework, the type system defines basic types shared by all languages that target the platform.
- An extensive class library. Instead of having to write vast amounts of code to handle common low-level programming operations, programmers can use a readily accessible library of types and their members from the .NET Framework Class Library.
- Development frameworks and technologies. The .NET Framework includes libraries for specific areas of application development. ASP.NET for web applications. ADO.NET for data access. Windows Communication Foundation for service-oriented applications.
- Language interoperability. With this feature, routines written in one language are accessible to other languages. Programmers can focus on creating applications in their preferred language or languages.
- Version compatibility. With rare exceptions, applications developed for a particular version of the .NET Framework can run on later versions without modification.
- Side-by-side execution. The .NET Framework helps resolve conflicts by allowing multiple versions of the common language runtime to exist on the same PC.
- Multitargeting. By targeting the .NET Framework Portable Class Library, developers can create assemblies that work on multiple .NET Framework platforms.
Microsoft .NET Framework – Pros & Cons
| Pros | Cons |
|---|---|
| ✓ Provides the runtime required for many legacy Windows applications, helping maintain compatibility with software built for the .NET Framework. | ✗ Limited to Windows and does not provide the cross-platform capabilities available in modern .NET releases. |
| ✓ Includes a mature Common Language Runtime (CLR) and extensive class libraries that offer reliable performance and long-term stability. | ✗ New application development is generally recommended on the latest .NET platform, as the .NET Framework is primarily maintained for existing software. |
| ✓ Supports multiple programming languages, including C#, Visual Basic .NET, and F#, allowing developers to build applications on a common framework. | ✗ Some modern APIs, performance improvements, and language features available in current .NET versions are not supported. |
| ✓ Integrates closely with Windows and Visual Studio, simplifying application development, debugging, and deployment. | ✗ Installing multiple .NET Framework versions may be necessary to run older applications that depend on specific releases. |
| ✓ Receives security and reliability updates through Windows Update, helping maintain compatibility and protect supported systems. | ✗ Migrating large .NET Framework applications to modern .NET can require code changes, especially for projects that rely on Windows-specific technologies. |
What’s New in Microsoft .NET Framework 4.8.1
Native support for Arm64
- Add native Arm64 support to the .NET Framework family to leverage the benefits of running workloads natively on Arm64 for better performance when compared to running x64 code emulated on Arm64.
Accessible Tooltips
- Tooltips now comply with the guidelines outlined in the WCAG2.1 content on Hover or Focus guidance. The requirements for tooltips are as follows:
- Tooltips must be displayed via mouse hover or by keyboard navigation to the control.
- Tooltips should be dismissible. Simple keyboard commands such as the ESC key should dismiss the tooltip.
- Tooltips should be hoverable. Users should be able to place their mouse cursor over the tooltip. This enables scenarios like using a magnifier to read the tooltip for low-vision users.
- Tooltips should be persistent. Tooltips should not automatically disappear after a certain time has elapsed. Rather, the tooltips should be dismissed by the user moving their mouse to another control, or by dismissing the tooltip as described above.
Windows Forms
- Added support for the UIA Text Pattern to enable assistive technology to traverse the content of a TextBox or similar text-based control letter by letter.
- Fixed high-contrast issues in several controls and changed the contrast ratio of selection rectangles to be darker and more visible.
- Fixed several DataGridView issues:
- Updated the scrollbar names for consistency.
- Fixed an issue where the Narrator was unable to focus on empty DataGridView cells.
- Enabled developers to set the localized control type property for Custom DataGridView cells.
- Updated the link color for DataGridViewLink cells to have better contrast with the background.
