9.0.0-preview.5.24306.3

The team has been working primarily on EF Core internals, so there are no new big features in EF Core 9 (EF9) Preview 5. 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 5. 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.

Enhanced database provider for Azure Cosmos DB for NoSQL

We are working on significant updates in EF9 to the EF Core database provider for Azure Cosmos DB for NoSQL. For preview 5, these include:

  • Support for hierarchical partition keys
  • Use of any numeric, bool, string, or value-converted type as a partition key

See Azure Cosmos DB for NoSQL in the What's New docs for more information.

Query translation improvements

EF9 preview 5 contains three small enhancements to query translation:

  • Optimization of queries using Count != 0 or Count > 0
  • Translations for TimeOnly.FromDateTime and TimeOnly.FromTimeSpan

See LINQ and SQL translation in the What's New docs for more information.

Everything else in preview 5

Preview 5 contains:

EF Core 9 preview 5 and Microsoft.Data.Sqlite contain work from the EF Team at Microsoft (@​roji @​AndriySvyryd @​maumar @​ajcvickers @​cincuranet @​SamMonoRT @​luisquintanilla).

9.0.0-preview.4.24267.1

The team has been working primarily on EF Core internals, so there are no new big features in EF Core 9 (EF9) Preview 4. 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 4. 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.

Enhanced database provider for Azure Cosmos DB for NoSQL

We are working on significant updates in EF9 to the EF Core database provider for Azure Cosmos DB for NoSQL. For preview 4, these include:

  • Role-based access control (RBAC) is supported by EF9 for both management and use of containers.
  • Azure Cosmos DB for NoSQL does not support synchronous (blocking) access from application code. EF Core now blocks synchronous access by default, helping people fall into the pit-of-success of using async I/O.
  • Cosmos primitive collection support has been updated to use the metadata and model building APIs from EF8

See Azure Cosmos DB for NoSQL in the What's New docs for more information.

GroupBy complex types

In preview 4, EF9 now supports grouping (GroupBy queries) that group by a complex type instance. The resulting SQL uses groups by all members, reflecting the value object semantics of complex types.

See GroupBy complex types in the What's New docs for more information.

Read-only primitive collections

EF8 introduced support for mapping arrays and mutable lists of primitive types. This has been expanded in EF9 to include read-only collections declared as IReadOnlyList, IReadOnlyCollection, or ReadOnlyCollection.

See Read-only primitive collections in the What's New docs for more information.

Everything else in preview 4

Preview 4 contains:

EF Core 9 preview 4 (and Microsoft.Data.Sqlite) contains work from the EF Team at Microsoft (@​roji @​AndriySvyryd @​maumar @​ajcvickers @​cincuranet @​SamMonoRT @​luisquintanilla) as well as contributions from the EF Core community. The community PRs in EF9 Preview 4 are:

9.0.0-preview.3.24172.4

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.

Everything else in preview 3

Preview 3 contains:

EF Core 9 preview 3 (and Microsoft.Data.Sqlite) contains work from the EF Team at Microsoft (@​roji @​AndriySvyryd @​maumar @​ajcvickers @​cincuranet @​SamMonoRT @​luisquintanilla) as well as contributions from the EF Core community. The community PRs in EF9 Preview 3 are:

9.0.0-preview.2.24128.4

The team has been working primarily on EF Core internals, so there are no new big features in EF Core 9 (EF9) Preview 2. 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 2, many contributed by our community. 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.

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 ToHashSet methods have existed since .NET Core 2.0. In EF9, the equivalent async methods have been added.
    • See New ToHashSetAsync<T> methods for full details.

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

Improved tooling

  • Fewer rebuilds when using dotnet ef tools
    • EF9 invalidates build caches less often, resulting in faster re-builds.
    • See Fewer rebuilds for full details.

Everything else in preview 2

Preview 2 contains:

EF Core 9 preview 2 (and Microsoft.Data.Sqlite) contains work from the EF Team at Microsoft (@​roji @​AndriySvyryd @​maumar @​ajcvickers) as well as contributions from the EF Core community. The community PRs in EF9 Preview 1 are:

9.0.0-preview.1.24081.2

The team has been working primarily on EF Core internals, so there are no new big features in EF Core 9 (EF9) Preview 1. 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 also several smaller enhancements included in preview 1. One of these might be just the thing you have been waiting for, so read on!

Improved queries

  • Prune columns passed to OPENJSON's WITH clause
    • EF9 removes unnecessary columns when calling OPENJSON WITH.
    • See Prune columns from JSON in the What's New docs for full details including runnable samples.
  • Translations involving GREATEST/LEAST
    • Several new translations have been introduced that use the GREATEST and LEAST SQL functions.
    • This includes translations of Math.Min and Math.Max in non-aggregate queries, as well as directly exposing the GREATEST and LEAST SQL functions in relational providers.
    • See GREATEST/LEAST translations in the What's New docs for full details including runnable samples.
  • 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 ExecuteUpdate as sugar for updating all member values.
    • See ExecuteUpdate for complex types in the What's New docs for full details including runnable samples.

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.
    • See Extensible model building conventions in the What's New docs for full details including runnable samples.
  • ApplyConfigurationsFromAssembly calls non-public constructors
