Announcing Entity Framework 6.3 Preview with .NET Core Support | .NET Blog
The first preview of the EF 6.3 runtime is now available in NuGet.
Note that the package is versioned as 6.3.0-preview5. We plan to continue releasing previews of EF 6.3 every month in alignment with the .NET Core 3.0 previews, until we ship the final version.
