Announcing .NET Framework 4.8 Early Access Build 3707

We have another early access build to share today! This release includes several accessibility, performance, reliability and stability fixes across the major framework libraries. We will continue to stabilize this release and take more fixes over the coming months and we would greatly appreciate it if you could help us ensure Build 3707 is a high-quality release by trying it out and providing feedback on the new features via the .NET Framework Early Access GitHub repository.

We’d also like to note that the set of supported OS platforms for this EAP build now match the same set of OS platforms supported for .NET 4.7.2 (with Windows 10, version 1809 and Windows Server 2019 being new additions).

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:
