Today, the .NET data team announces the first preview release of
EF Core 7.0 (EF7).
This release contains mostly bug fixes and foundation work for larger features that will land in later previews. Be sure to read the full plan for EF7 to learn what’s on the roadmap.
EF7 currently targets .NET 6. This will likely be updated to .NET 7 as we near the release.
EF7 will not run on .NET Framework.
How to get EF7 previews
EF7 is distributed exclusively as a set of NuGet packages.
For example, to add the SQL Server provider to your project, you can use the following command using the dotnet tool:
dotnet add package Microsoft.EntityFrameworkCore.SqlServer –version 7.0.0-preview.1.22076.6
This following table links to the preview 1 versions of the EF Core packages and describes what they are used for.
The main EF Core package that is independent of specific database providers
Database provider for Microsoft SQL Server and SQL Azure
SQL Server support for spatial types
Database provider for SQLite that includes the native binary for the database engine
Database provider for SQLite without a packaged native binary
SQLite support for spatial types
Database provider for Azure Cosmos DB
The in-memory database provider
Shared design-time components for EF Core tools
Lazy-loading and change-tracking proxies
Decoupled EF Core abstractions; use this for features like extended data annotations defined by EF Core
Shared EF Core components for relational database providers
C# analyzers for EF Core
Installing the EF7 Command Line Interface (CLI)
Before you can execute EF7 Core migration or scaffolding commands, you’ll have to install the CLI package as either a global or local tool.
To install the preview tool globally, install with:
dotnet tool install –global dotnet-ef –version 7.0.0-preview.1.22076.6
If you already have the tool installed, you can upgrade it with the following command:
dotnet tool update –global dotnet-ef –version 7.0.0-preview.1.22076.6
It’s possible to use this new version of the EF7 CLI with projects that use older versions of the EF Core runtime.
What’s new in EF7 Preview 1
The list of issues that are addressed in preview 1 is available on GitHub. There are over 80 issues addressed. We’d like to extend a special thanks to our community contributors to this preview, including:
EF7 previews are aligned with .NET 7 previews. These previews tend to lag behind the latest work on EF7. Consider using the daily builds instead to get the most up-to-date EF7 features and bug fixes.
As with the previews, the daily builds require .NET 6.
