See the full list of EF7 RC1 changes on GitHub.
For a detailed look at what’s new in EF7, with working samples, check out our newly updated What’s New in EF7 documentation. You can also read the feature deep dives in our previous blog posts:

EF7 Prerequisites
- EF7 targets .NET 6, which means it can be used on .NET 6 (LTS) or .NET 7.
- EF7 will not run on .NET Framework.
EF7 is the successor to EF Core 6.0, not to be confused with EF6. If you are considering upgrading from EF6, please read our guide to port from EF6 to EF Core.
How to get EF7 RC1
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-rc.1.22426.7This following table links to the RC1 versions of the EF Core packages and describes what they are used for.
| Package | Purpose |
|---|---|
| Microsoft.EntityFrameworkCore | The main EF Core package that is independent of specific database providers |
| Microsoft.EntityFrameworkCore.SqlServer | Database provider for Microsoft SQL Server and SQL Azure |
| Microsoft.EntityFrameworkCore.SqlServer.NetTopologySuite | SQL Server support for spatial types |
| Microsoft.EntityFrameworkCore.Sqlite | Database provider for SQLite that includes the native binary for the database engine |
| Microsoft.EntityFrameworkCore.Sqlite.Core | Database provider for SQLite without a packaged native binary |
| Microsoft.EntityFrameworkCore.Sqlite.NetTopologySuite | SQLite support for spatial types |
| Microsoft.EntityFrameworkCore.Cosmos | Database provider for Azure Cosmos DB |
| Microsoft.EntityFrameworkCore.InMemory | The in-memory database provider |
| Microsoft.EntityFrameworkCore.Tools | EF Core PowerShell commands for the Visual Studio Package Manager Console; use this to integrate tools like scaffolding and migrations with Visual Studio |
| Microsoft.EntityFrameworkCore.Design | Shared design-time components for EF Core tools |
| Microsoft.EntityFrameworkCore.Proxies | Lazy-loading and change-tracking proxies |
| Microsoft.EntityFrameworkCore.Abstractions | Decoupled EF Core abstractions; use this for features like extended data annotations defined by EF Core |
| Microsoft.EntityFrameworkCore.Relational | Shared EF Core components for relational database providers |
| Microsoft.EntityFrameworkCore.Analyzers | C# analyzers for EF Core |
We also published the release candidate 1 of the Microsoft.Data.Sqlite.Core provider for ADO.NET.
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 RC tool globally, install with:
dotnet tool install --global dotnet-ef --version 7.0.0-rc.1.22426.7 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-rc.1.22426.7 It’s possible to use this new version of the EF7 CLI with projects that use older versions of the EF Core runtime.
Daily builds
EF7 release candidates are aligned with .NET 7 release candidates. These releases 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 release candidates, the daily builds require .NET 6.
