• Make basic EF scenarios work under aggressive trimming
• Entity splitting support
• Support for GroupBy entityType
• Support GroupJoin when it is final query operator
• ExecuteUpdate: Add SetProperty overload that accepts a value directly (no lambda)
• Support sproc input/output parameters on non-concurrency-token properties
• Implement TagWith for ExecuteUpdate and DeleteUpdate
• ExecuteDelete for owner when only its owned types are sharing the same table
• Stop scaffolding DbSet initialization to null!
• CSharpHelper: support more types of collection literals
• Map JSON values stored in database to EF properties
• ExecuteUpdate/Delete (AKA bulk update, without loading data into memory)
• Code templates for scaffolding entity types and DbContext from an existing database
• Support raw SQL Queries for basic types like Guid, DateTime and int
• Allow applications to create model building conventions (aka public conventions)
• Cosmos: Support AAD RBAC via the ClientSecretCredential
• Map inserts, updates, and deletes (CUD operations) to stored procedures
• Add a static flag in EF that will be set when code is being executed for design-time discover
• Support sequence key generation on SQL Server, which is useful for Table-per-concrete-type (TPC) mapping
• Allow null connection string to be passed to UseProvider methods
• Downgrade the ContextInitialized event from Information to Debug
• Get an EntityEntry for Shared Entity Types
• Make EntityEntryGraphIterator publicly usable
• Support unidirectional many-to-many relationships
• Translate string.Join and string.Concat
• RevEng: Enable generating IEntityTypeConfiguration classes (avoids large OnModelCreating)
• Interception to modify the LINQ expression tree
• Interception for DbUpdateConcurrencyException
• Add interception event to be fired when EF has finished consuming a result set
• Add events for DetectChanges/state change
• ChangeTracker: New event for "entity about to get tracked"
• Translate EnvelopeCombiner.CombineAsGeometry aggregate function
• SQL Server: Translate statistics aggregate functions
• Filtered Includes for hidden navigation properties
• Make it easier to pass a CancellationToken to FindAsync
• Interception for object materialization (a.k.a. "ObjectMaterialized")
• Provide a hook for identity resolution
• Create lazy-loading and change-tracking proxy types lazily
• Compiled model: Allow use of lazy loading and change tracking proxy types
• Full support for custom provider aggregate functions
• Spatial: Translate aggregate functions
• Allow specifying different column names per table in TPT, TPC or entity splitting
• Support for custom proxy generation
• TPC inheritance mapping pattern
• DeleteBehaviorAttribute
• Translate GetType() for entity types with inheritance
• Delay DbCommandInterceptor.CommandCreated until DbCommand properties are initialized
• Remove unnecessary extra batches in SaveChanges
• Don't check for a connection string until after ConnectionOpening has been called
• Add ConnectionCreating/ConnectionCreated to DbConnectionInterceptor
• Migration name filter
• Add support for AT TIME ZONE
• GroupBy aggregate lifting
• Pascal-case the DbContext name when scaffolding
• Support value generation with converters
• Improve batching performance when using TPH mappings
• Attribute (Data Annotations) mapping for composite primary keys
• SQL Server UTF8 collations
• Stop wrapping single changes in transactions where possible
• Use RETURNING/OUTPUT clause for UPDATE/DELETE
• SQLite SaveChanges: Use RETURNING clause
• SQL Server: Optimize SQL Server OUTPUT clause usage when retrieving database-generated values
• Stop automatically deleting orphans for optional relationships with cascade delete configured
• Empty default interface implementations for all interceptor interface methods
• Temporal tables support for owned entities and other table splitting scenarios
• Support for index ordering (ASC/DESC)
• Support "non-rooted" query expressions in compiled queries
• Property/Reference/etc overloads that take IProperty/INavigation
• Distinguish cancellation from failure to allow different logging strategies
• Lift table from subquery when joining if no additional operations
• DiagnosticSuppressor for CS8618 for DbSet properties
• Stop generating a default DbContext constructor when using dotnet ef dbcontext scaffold --no-onconfiguring
• Robust and extensible SQL precedence/parentheses mechanism
• Translation for string.IndexOf(string, int)
• Support SqlNullabilityProcessor and COALESCE with more than two arguments
• Support Contains when using a IReadOnlySet
• Overload of EnableRetryOnFailure that allows specifying errorCodesToAdd without count / delay
