Announcing .NET Framework 4.8 Early Access Build 3734

[Brink]

We are getting closer to the final version now! This release includes several accessibility, performance and reliability fixes across the major framework libraries. We will continue to stabilize this release and take more fixes over the coming weeks and we would greatly appreciate it if you could help us ensure Build 3734 is a high-quality release by trying it out and providing feedback on the new features via the .NET Framework Early Access GitHub repository.

Supported Windows Client versions: Windows 10 version 1809, Windows 10 version 1803, Windows 10 version 1709, Windows 10 version 1703, Windows 10 version 1607, Windows 8.1, Windows 7 SP1

Supported Windows Server versions: Windows Server 2019, Windows Server version 1803, Windows Server version 1709, Windows Server 2016, Windows Server 2012, Windows Server 2012 R2, Windows Server 2008 R2 SP1

This build includes an updated .NET 4.8 runtime as well as the .NET 4.8 Developer Pack (a single package that bundles the .NET Framework 4.8 runtime, the .NET 4.8 Targeting Pack and the .NET Framework 4.8 SDK). Please note: this build is not supported for production use.

Next steps:
To explore the new build, download the .NET 4.8 Developer Pack. Instead, if you want to try just the .NET 4.8 runtime, you can download either of these:

• .NET 4.8 Web Installer – requires an internet connection during installation
• .NET 4.8 Offline installer – can be downloaded and installed later in a disconnected state

You can checkout the fixes included in this preview build or if you would like to see the complete list of improvements in 4.8 so far, please go here.

.NET Framework build 3734 is also included in the next update for Windows 10. You can sign up for Windows Insiders to validate that your applications work great on the latest .NET Framework included in the latest Windows 10 releases.

Thanks!
