The fourth preview of Entity Framework Core (EF Core) 8 is available on NuGet today!

Basic information

EF Core 8, or just EF8, is the successor to EF Core 7, and is scheduled for release in November 2023, at the same time as .NET 8.

EF8 previews currently target .NET 6, and can therefore be used with either .NET 6 (LTS) or .NET 7. This will likely be updated to .NET 8 as we near release.

EF8 will align with .NET 8 as a long-term support (LTS) release. See the .NET support policy for more information. 

To get started with ASP.NET Core in .NET Core 3.0 Preview 9 install the .NET Core 3.0 Preview 9 SDK.

If you’re on Windows using Visual Studio, install the latest preview of Visual Studio 2019.

.NET Core 3.0 Preview 9 requires Visual Studio 2019 16.3 Preview 3 or later. 

.NET 7 brings your apps increased performance and new features for C# 11/F# 7, .NET MAUI, ASP.NET Core/Blazor, Web APIs, WinForms, WPF and more. With .NET 7, you can also easily containerize your .NET 7 projects, set up CI/CD workflows in GitHub actions, and achieve cloud-native observability.

Thanks to the open-source .NET community for your numerous contributions that helped shape this .NET 7 release. 28k contributions made by over 8900 contributors throughout the .NET 7 release!

.NET remains one of the fastest, most loved, and trusted platforms with an expansive .NET package ecosystem that includes over 330,000 packages.
