Today, the Entity Framework Core team announces the second release candidate (RC2) of EF Core 5.0. This is
a feature complete release candidate of EF Core 5.0 and ships with a “go live” license. You are supported
using it in production. This is a great opportunity to start using EF Core 5.0 early while there is still time to
fix remaining issues. We’re looking for reports of any remaining critical bugs that should be fixed before the
final release.

Prerequisites

EF Core 5.0 will not run on .NET Standard 2.0 platforms, including .NET Framework.

How to get EF Core 5.0 Release Candidate 2

EF Core 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 5.0.0-rc.2.20475.6

This following table links to the RC2 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.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

Installing the EF Core Command Line Interface (CLI)

As with EF Core 3.0 and 3.1, the EF Core CLI is no longer included in the .NET Core SDK. Before you can execute EF
Core migration or scaffolding commands,
you’ll have to install this package as either a global or local tool.

EF Core 5.0 RC2

To install the RC2 tool globally the first time, use:

dotnet tool install --global dotnet-ef --version 5.0.0-rc.2.20475.6

If you already have the tool installed, update it with:

dotnet tool update --global dotnet-ef --version 5.0.0-rc.2.20475.6

It’s possible to use this new version of the EF Core CLI with projects that use older versions of the EF Core
runtime.

What’s New in EF Core 5 RC2

We maintain documentation covering new
features introduced into each release
. This release included several bug fixes.

Daily builds

EF Core previews and release candidates are aligned with the .NET 5 release cycle. These releases tend to lag behind
the latest work on EF Core. Consider using the daily builds instead to get the
most up-to-date EF Core features and bug fixes.

As with the previews, the daily builds do not require .NET 5; they can be used with GA/RTM release of .NET Core 3.1.
Daily builds are considered stable.

Contribute to .NET 5

The .NET documentation team is reorganizing .NET content to
better match the workloads you build with .NET. This includes a new .NET Data landing page that will link out to data-related
topics ranging from EF Core to APIs, Big Data, and Machine learning. The planning and execution will be done
completely in the open on GitHub. This is your opportunity to help shape the hierarchy and content to best fit your
needs as a .NET developer. We look forward to your contributions!

The EF Core Community Standup

The EF Core team is now live streaming every other Wednesday at 10am Pacific Time, 1pm Eastern Time, or 17:00 UTC.
Join the stream to ask questions about the EF Core topic of your choice, including the latest release candidate.
Visit the .NET Community Standup page to
preview upcoming shows and view recordings from past shows.

Documentation and Feedback

The starting point for all EF Core documentation is docs.microsoft.com/ef/.

Please file issues found and any other feedback on the dotnet/efcore
GitHub repo
