Microsoft released the final version of the Microsoft .NET Framework 4.8 on April 18, 2019. The new installer for the version is available as a web installer and offline installer; since Microsoft prefers distribution via the web installer, it is difficult to find working offline installer links. You find a working offline installer link attached to this article.
The Microsoft .NET Framework 4.8 is a new version of Microsoft’s popular framework. It includes new features, fixes and improvements compared to previous versions.
Microsoft released the .NET Framework 4.8 for Windows 7 Service Pack 1, Windows 8.1, and Windows 10, and all server platforms starting with Windows Server 2008 R2 Service Pack 1 (means Server 2012 R2, 2016, and 2019 are supported as well). Windows 10 version 1903, the May 2019 Update version of the operating system, includes version 4.8 of the .NET Framework already.
The changelog on the Microsoft Docs website highlights new features and changes in the new release. The log is quite technical in nature and intended for programmers who use the framework more than it is for Windows users and administrators who install it.
New features in .NET Framework 4.8 include high-DPI improvements such as improved support for Windows Forms interoperation in high-DPI WMF applications on platforms that support mixed-mode DPI scaling or support for Per-Monitor V2 DPI Awareness.
Other changes include an updated Zlib library that is used for data compression, and a new ServiceHealthBehaviorWCF service that extends IServiceBehavior.
