IEntityMaterializerSource Interface

Definition

Namespace:

Microsoft.EntityFrameworkCore.Query

Assembly:

Microsoft.EntityFrameworkCore.dll

Package:

Microsoft.EntityFrameworkCore v8.0.0

Defines a source for generating Expression trees that read values from a ValueBuffer or creates entity instances.

This type is typically used by database providers (and other extensions). It is generally not used in application code.

Derived

Remarks

The service lifetime is Singleton. This means a single instance is used by many DbContext instances. The implementation must be thread-safe. This service cannot depend on services registered as Scoped.

See Implementation of database providers and extensions and How EF Core queries work for more information and examples.
