Releases: dotnet/efcore
EF Core 6.0.30
This is a patch release of EF Core 6.0 containing only updates to dependencies. There are no additional fixes in this release beyond those already shipped in EF Core 6.1.29.
EF Core 9.0 Preview 3
The team has been working primarily on EF Core internals, so there are no new big features in EF Core 9 (EF9) Preview 3. However, this means we really need people like you to run your code on these new internals and report back what you find. We want to fix bugs in the new internals as soon as possible in order to have a strong GA release later in the year.
That being said, there are several smaller enhancements included in preview 3. For full details, see What's new in EF Core 9. To discuss the EF9 release, go to Try EF Core 9 now! on GitHub.
Auto-compiled models
Auto-compiled models allow the EF Core compiled model to be automatically regenerated when the model project is built. This means you no longer need to remember to re-run the dotnet ef dbcontext optimize command after your EF model changes. See Auto-compiled models in the What's New docs for more information.
Sugar for HierarchyId path generation
First class support for the SQL Server HierarchyId type was added in EF8. In EF9, a sugar method has been added to make it easier to create new child nodes in the tree structure. See Sugar for HierarchyId path generation in the What's New docs for more information.

Improved queries
- Inlined uncorrelated subqueries
- In EF8, an IQueryable referenced in another query may be executed as a separate database roundtrip.
- See Inlined uncorrelated subqueries for full details.
- New ToHashSetAsync methods
- The
ToHashSetmethods have existed since .NET Core 2.0. In EF9, the equivalent async methods have been added. - See New
ToHashSetAsync<T>methods for full details.
- The
Improved model building
- Specify caching for sequences
- EF9 allows setting the caching options for database sequences for any relational database provider that supports this.
- See Specify caching for sequences for full details.
- Specify fill-factor for keys and indexes
- EF9 supports specification of the SQL Server fill-factor when using EF Core Migrations to create keys and indexes.
- See Specify fill-factor for keys and indexes for full details.
Improved tooling
- Fewer rebuilds when using
dotnet eftools- EF9 invalidates build caches less often, resulting in faster re-builds.
- See Fewer rebuilds for full details.

That being said, there are also several smaller enhancements included in preview 1. One of these might be just the thing you have been waiting for, so read on!
- Discussion

- Documentation & Samples
Improved queries

OPENJSON WITH. - See Prune columns from JSON in the What's New docs for full details including runnable samples.
- EF9 removes unnecessary columns when calling
- Translations involving GREATEST/LEAST
- Several new translations have been introduced that use the
GREATESTandLEASTSQL functions. - This includes translations of
Math.MinandMath.Maxin non-aggregate queries, as well as directly exposing theGREATESTandLEASTSQL functions in relational providers. - See GREATEST/LEAST translations in the What's New docs for full details including runnable samples.
- Several new translations have been introduced that use the
- Force or prevent query parameterization
- Except in some special cases, EF Core parameterizes variables used in a LINQ query, but includes constants in the generated SQL. EF9 allows constants to be translated to parameters and variables to be translated to constants on a case to case basis.
- See Force or prevent query parameterization in the What's New docs for full details including runnable samples.
ExecuteUpdate
- Allow passing complex type instances to ExecuteUpdate
- EF9 supports directly passing complex type instances to
ExecuteUpdateas sugar for updating all member values. - See ExecuteUpdate for complex types in the What's New docs for full details including runnable samples.
- EF9 supports directly passing complex type instances to
Temporal tables
- Small migrations for temporal tables
- The migration created when changing an existing table into a temporal table has been reduced in size for EF9.
- See Improved temporal table migrations in the What's New docs for full details including runnable samples.
Model building
- Make existing model building conventions more extensible
- In EF9, we have made it easier to extend some of the existing conventions, such as those for property and key discovery.

- ApplyConfigurationsFromAssembly calls non-public constructors
- In EF9, we have both improved the error messages generated when this fails, and also enabled instantiation by non-public constructor.
