Called immediately before EF is going to throw a DbUpdateConcurrencyException.

public virtual System.Threading.Tasks.ValueTask<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult> ThrowingConcurrencyExceptionAsync (Microsoft.EntityFrameworkCore.Diagnostics.ConcurrencyExceptionEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult result, System.Threading.CancellationToken cancellationToken = default);

abstract member ThrowingConcurrencyExceptionAsync : Microsoft.EntityFrameworkCore.Diagnostics.ConcurrencyExceptionEventData * Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult>

Public Overridable Function ThrowingConcurrencyExceptionAsync (eventData As ConcurrencyExceptionEventData, result As InterceptionResult, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of InterceptionResult)

Parameters

eventData: ConcurrencyExceptionEventData

Contextual information about the concurrency conflict.

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 throw the exception. If IsSuppressed is true, then EF will not throw the exception. An implementation of this method for any interceptor that is not attempting to suppress setting property values must return the result value passed in.

Implements

ThrowingConcurrencyExceptionAsync(ConcurrencyExceptionEventData, InterceptionResult, CancellationToken)
