Called just before EF intends to create a transaction savepoint.

public System.Threading.Tasks.ValueTask<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult> CreatingSavepointAsync (System.Data.Common.DbTransaction transaction, Microsoft.EntityFrameworkCore.Diagnostics.TransactionEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult result, System.Threading.CancellationToken cancellationToken = default);

public virtual System.Threading.Tasks.ValueTask<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult> CreatingSavepointAsync (System.Data.Common.DbTransaction transaction, Microsoft.EntityFrameworkCore.Diagnostics.TransactionEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult result, System.Threading.CancellationToken cancellationToken = default);

abstract member CreatingSavepointAsync : System.Data.Common.DbTransaction * Microsoft.EntityFrameworkCore.Diagnostics.TransactionEventData * Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult>

Public Function CreatingSavepointAsync (transaction As DbTransaction, eventData As TransactionEventData, result As InterceptionResult, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of InterceptionResult)

Public Overridable Function CreatingSavepointAsync (transaction As DbTransaction, eventData As TransactionEventData, result As InterceptionResult, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of InterceptionResult)

Parameters

transaction: DbTransaction

The transaction.

eventData: TransactionEventData

Contextual information about connection and transaction.

result: InterceptionResult

Represents the current result if one exists. This value will have IsSuppressed set to true if some previous interceptor suppressed execution by calling Suppress(). This value is typically used as the return value for the implementation of this method.

cancellationToken: CancellationToken

A CancellationToken to observe while waiting for the task to complete.

Returns

ValueTask<InterceptionResult>

If IsSuppressed is false, then EF will continue as normal. If IsSuppressed is true, then EF will suppress the operation it was about to perform. An implementation of this method for any interceptor that is not attempting to suppress the operation is to return the result value passed in.

Exceptions

OperationCanceledException

If the CancellationToken is canceled.
