NET Framework 4.8 Early Access build 3646 is available!

Today, we are happy to share an Early Access build for the .NET Framework 4.8. This includes an updated .NET 4.8 runtime as well as the .NET 4.8 Developer Pack (a 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 help us ensure this is a high quality and compatible release by trying out this build and exploring the new features.

**Next steps:**
To explore the new features, download the [.NET 4.8 Developer Pack build 3646](https://go.microsoft.com/fwlink/?LinkId=2018486). Instead, if you want to try just the .NET 4.8 runtime, you can download either of these:
• [.NET 4.8 Web Installer](https://go.microsoft.com/fwlink/?LinkId=2018525) - requires an internet connection during installation
• [.NET 4.8 Offline installer](https://go.microsoft.com/fwlink/?LinkId=2018531) - can be downloaded and installed later in a disconnected state

Please provide your feedback by [reporting an issue at the .NET Framework Early Access GitHub repository](https://github.com/Microsoft/dotnet-framework-early-access/issues/new).

**Note**: this release is still under development, you can expect to see more features and fixes in future preview builds. Also, a reminder that this build is not supported for production use.

• **[Runtime]** JIT and NGEN improvements
