The Wolf at the End of the Desert
Entity Framework Core 7 (EF7) Release Candidate 1 has been released! The team focuses on solving defects, making minor improvements, and putting the final touches on functionality.
在 GitHub 上查看EF7 RC1 更改的完整列表。
要详细了解 EF7 中的新增功能以及工作示例，请查看我们最新更新的 EF7 文档中的新增功能。您还可以阅读我们之前的博客文章中的功能深入探讨：
- EF7 Preview 7 – Interceptors
- EF7 Preview 6 – Performance
- EF7 Preview 5 – Table-per-Concrete Type (TPC)
- EF7 Preview 4 – DDD-friendly converters
- [EF7 Preview 3 – customizable database-first scaffolding templates](https://devblogs.microsoft.com/dotnet/
- EF7 Preview 1 – the beginning
EF 7 Prerequisites
- EF7 is targeted at. NET 6, which means it can be used on either. NET 6 (LTS) or. NET 7.
- EF 7 will not run on the. NET Framework.
EF7 是 EF Core 6.0 的继承者，不要与 EF6混淆。如果您正在考虑从 EF6 升级，请阅读我们的从 EF6 移植到 EF Core 的指南。
How to get the EF7 RC 1
EF7 is only distributed as a set of NuGet packages. For example, to add a SQL Server provider to your project, you can use the following command through the dotnet tool:
dotnet add package Microsoft.EntityFrameworkCore.SqlServer --version 7.0.0-rc.1.22426.7
The following table links to the RC1 version of the EF Core package and describes their purpose.
| package | objective |
|---|---|
| Microsoft.EntityFrameworkCore | Main EF Core package independent of specific database providers |
| Microsoft.EntityFrameworkCore.SqlServer | Database providers for Microsoft SQL Server and SQL Azure |
| Microsoft.EntityFrameworkCore.SqlServer.NetTopologySuite | SQL Server support for spatial types |
| Microsoft.EntityFrameworkCore.Sqlite | SQLite's database provider, including native binaries for the database engine |
| Microsoft.EntityFrameworkCore.Sqlite.Core | SQLite's database provider, no packaged native binaries |
| Microsoft.EntityFrameworkCore.Sqlite.NetTopologySuite | SQLite support for spatial types |
| Microsoft.EntityFrameworkCore.Cosmos | Database provider for Azure Cosmos DB |
| Microsoft.EntityFrameworkCore.InMemory | in-memory database provider |
| Microsoft.EntityFrameworkCore.Tools | EF Core PowerShell command for the Visual Studio Package Manager console; use it to integrate tools such as scaffolding and migration with Visual Studio |
| Microsoft.EntityFrameworkCore.Design | Shared design-time components for EF Core tools |
| Microsoft.EntityFrameworkCore.Proxies | Delayed loading and change tracking agents |
| Microsoft.EntityFrameworkCore.Abstractions | Decoupling EF Core abstraction; use this for functions such as extended data annotations defined by EF Core |
| Microsoft.EntityFrameworkCore.Relational | Shared EF Core components for relational database providers |
| Microsoft.EntityFrameworkCore.Analyzers | EF Core's C#analyzer |
我们还发布了ADO.NET的Microsoft.Data.Sqlite.Core提供程序的候选版本 1 。
Install the EF 7 Command Line Interface (CLI)
Before executing EF 7 Core migration or scaffolding commands, you must install CLI packages as global or local tools.
To install RC tools globally, install them using the following command:
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
This new version of EF 7 CLI can be used for projects that use older versions of EF Core runtimes.
daily build
EF7 候选版本与 .NET 7 候选版本一致。这些版本往往落后于 EF7 的最新工作。考虑使用每日构建来获取最新的 EF7 功能和错误修复。
Like the release candidate, daily builds require. NET 6.
