Announcing .NET 5.0 Preview 6

Today, we’re releasing .NET 5.0 Preview 6. It contains a small set of new features and performance improvements. The .NET 5.0 Preview 4 post covers what we are planning to deliver with .NET 5.0. Most of the features are now in the product, but some are not yet in their final state. We expect that the release will be feature-complete with Preview 8.


You can download .NET 5.0 Preview 6, for Windows, macOS, and Linux:

ASP.NET Core and EF Core are also being released today. Note: EF Core 5.0 will not support .NET Standard 2.0 or .NET Framework. Read the EF Core post to learn more.


You need to use Visual Studio 2019 16.7 to use .NET 5.0. .NET 5.0 is now supported with Visual Studio for Mac. Install the latest version of the C# extension, to use .NET 5.0 with Visual Studio Code.

Release notes:


Windows ARM64 Update

We announced support for Windows ARM64 as part of Preview 4. At that time, we had only enabled console and ASP.NET Core apps on Windows ARM64. The Preview 6 SDK now includes support for Windows Forms. That means you can build and run Windows Forms apps on Windows ARM64 devices, just like you would on x64. We’re still working on adding support for WPF on Windows ARM64.


You can see a sample Windows Forms app running on an ARM64 laptop, shown below.
