Interface IUpdateAdapterFactory

Namespace

Microsoft.EntityFrameworkCore.Update

Assembly

Microsoft.EntityFrameworkCore.dll

Factory for creating IUpdateAdapter instances.

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

public interface IUpdateAdapterFactory

Remarks

The service lifetime is Scoped. This means that each DbContext instance will use its own instance of this service. The implementation may depend on other services registered with any lifetime. The implementation does not need to be thread-safe.

See Implementation of database providers and extensions for more information and examples.

Methods

Create()

Creates a tracker for the model currently in use.

IUpdateAdapter Create()

Returns

IUpdateAdapter

The new tracker.

CreateStandalone(IModel?)

Creates a standalone tracker that works with its own IStateManager and hence will not impact tracking on the state manager currently in use.

IUpdateAdapter CreateStandalone(IModel? model = null)

Parameters

model IModel

The model for which a tracker is needed, or null to use the current model.

Returns

IUpdateAdapter

The new tracker.

Remarks

The Entries from this update adapter should be used explicitly once they have been setup. They will not be visible to other parts of the stack, including SaveChanges().
