Microsoft .NET Framework 4.8.1 is a runtime execution environment that manages applications focusing on the .NET Framework. It consists of the common language runtime, which provides memory management and different system services. Also, an in-depth class library, allows programmers to benefit from strong, reliable code for all main areas of app growth.
This redistributable bundle installs the .NET Framework runtime and related files required to run applications developed to focus on the .NET Framework.
The Microsoft .NET Framework 4.8.1 is an extremely suitable, 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 bundle can be utilized in conditions the place the web installer can’t be used as a result of an absence of internet connectivity.
The .NET Framework is a managed execution environment that provides a wide range of services to its running applications. It consists of two main components: the common language runtime (CLR), which is the execution engine that handles running applications. And the .NET Framework Class Library provides a library of examined, reusable code that developers can call from their very own applications.
Microsoft .NET Framework provides services:
- Memory management. In many programming languages, programmers are responsible for allocating and releasing memory and for dealing with 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, basic types are defined by the type system and are frequent in all languages that focus on the .NET Framework.
- An extensive class library. Instead of getting to write down huge quantities of code to deal with 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 particular areas of application improvement. 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 a single language are accessible to different languages, and programmers can give attention to creating applications for their most popular language or languages.
- Version compatibility. With uncommon exceptions, applications that can be developed by using a specific version of the .NET Framework can run without modification on a later version.
- Side-by-side execution. The .NET Framework helps resolve version conflicts by allowing multiple versions of the common language runtime to exist on the same computer. This signifies that multiple versions of applications may also coexist and that an application can run on the version of the .NET Framework with which it was built.
- Multitargeting. By focusing on the .NET Framework Portable Class Library, developers can create assemblies that work on multiple .NET Framework platforms.
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.
- tooltips now comply with the guidelines outlined in the WCAG2.1 content on Hover or Focus guidance. The requirements for tooltips require the following:
- Tooltips must display either via mouse hover or by keyboard navigation to the control.
- Tooltips should be dismissible. That is, a simple keyboard command like 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 be able 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.
- 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 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.
